Question 6

How to Upgrade Firmware on Smart-UPS Models Using the Firmware Upgrade Wizard

Accepted Answer

Introduction: Most Smart-UPS models support user-upgradeable firmware. Firmware upgrades can provide product improvements, feature enhancements, and cybersecurity remediations throughout the product lifecycle. Important: During a firmware upgrade, battery backup is unavailable. Equipment powered by the UPS will not be protected from power failures. Depending on the UPS model, UPS output power may need to be turned off before the firmware can be upgraded. The Firmware Upgrade Wizard will advise you on how to proceed.Certain UPS models do not support firmware upgrade using a USB connection. To upgrade the firmware of these UPS units using the Firmware Upgrade Wizard, a local connection via serial cable must be used. The serial cable supplied with the UPS must be used.Ensure the computer remains powered on and the communication connection between the UPS and the computer is maintained throughout the firmware upgrade process.Schneider Electric recommends upgrading Smart-UPS On-Line SRT, XP, and XU firmware only when instructed by Schneider Electric Technical Support or when advised through an official Schneider Electric communication. To view different UPS firmware upgrade methods, refer to FA164737.

Failure to do so may result in unexpected operation of your AP9635 Network Management Card 2. NOTE: Some USB flash drives are not compatible with the NMC2 devices. Secondly, the flash drive’s file system must be FAT, FAT16, or FAT32. (NTFS will not work).1. Obtain the latest firmware files from apc.com and extract them to a folder. Please note, USB may not allow for a firmware downgrade. You must use a manual method to accomplish a downgrade.2. Create a folder on your USB flash drive called apcfirm .3. From the latest firmware files that you downloaded, add to the apcfirm folder the binary files for the firmware modules that you would like to upgrade. Some examples of the binary files for the three firmware modules follow: Firmware ModuleBinary File APC Boot Monitor apc_hw05_bootmon_109.bin APC Operating System (AOS) apc_hw05_aos_712.bin Application Module apc_hw05_sumx_712.bin Language Pack* sumx_712_frFrdeDeruRuitItesEs.lpk *Optional language pack upgrades/changes are supported via USB if the device you’re upgrading already has BootMonitor v1.0.8 or higher (BootMonitor performs the upgrading function). NOTE: Not all NMC2 applications support language packs. 4. Use a text editor such as Microsoft Notepad to create a file called upload.rcf. NOTE: (Ensure that file extensions are visible so that your file does not get named upload.rcf.txt. In Windows, this option can be edited in Folder Options->View->Hide extensions for known file types within Control Panel. Make sure that option is unselected.) Add to the file a line for each firmware module that you want to upgrade as shown below (replace “xx” with the version of firmware you will be upgrading to): BM=apc_hw05_bootmon_xx.binAOS=apc_hw05_aos_xx.binAPP=apc_hw05_sumx_xx.binLANG=sumx_xx_frFrdeDeruRuitItesEs.lpk 5.

Question 8

How do I update my Smart-UPS firmware using the command line interface of my Network Management Card?

Accepted Answer

Issue:Because the Firmware Upgrade Wizard is the most universal and preferred method of updating, we recommend using the APC Firmware Upgrade Wizard whenever possible. The APC Firmware Upgrade Wizard guides you through the update process and provides a consistent update experience. The Firmware Upgrade Wizard is available in FA279197. Instructions are being provided here for users that are unable use the Firmware Upgrade Wizard and wish to update their Smart-UPS Firmware using command line tools and an APC Network Management Card (NMC). For those who wish to update their Smart-UPS Firmware using the NMC’s web interface, see FA170679.Product Line:Smart-UPS models with the prefixes SMT, SMX, SRT, SRTL, XU, and XP with a SmartSlot or Embedded NMC. If the ID of your UPS is not available in the table below, it means there are no firmware updates available for that UPS at this time. Environment: Command line terminal emulator and file transfer toolsSupported UPS model listed aboveUPS Network Management Card 2 (AP9630, AP9630CH, AP9631, AP9631CH, or embedded NMC2) with SUMX application firmware v6.4.0 or higher UPS Network Management Card 3 (AP9640, AP9641, AP9643, or embedded NMC3) with SU application firmware 1.0 or higherCorrect firmware file for the particular UPS available in the table below Resolution:Follow the steps below to determine your current NMC type and firmware revision, select the proper UPS firmware image, and update the UPS firmware via the Network Management Card’s Command Line Interface (CLI). Step 1 - Using an SSH client of your choice, connect to the IP address of the Network Management Card.Note: If required, Open SSH can be added using Windows Manage Optional Features.Example of using Windows Command Prompt to connect via SSH:ssh -c aes256-cbc apc@10.0.0.1Notes: This SSH command is for OpenSSH. The command may differ depending on the SSH tool used.The username may be different that the “apc” username used in this example. Using the web interface of the NMC, navigate to the “SSH Host Key” in the “Console” found in the “Network” section of the “Configuration” menu. Verify and take note of the SSH Key.Compare the SSH key to the RSA fingerprint displayed in the command line terminal window. To display the fingerprint in the same format as shown in the NMC web interface, the <-o FingerPrintHash=md5> argument can be used. Example:ssh -c aes256-cbc -o FingerPrintHash=md5 apc@10.0.0.1Notes: Telnet can be used if enabled, but it is not recommended due to lack of encryption, and the examples shown here are just for reference.Example of using Windows Command Prompt to connect via Telnet: From a computer that has access to the network on which the NMC is installed, at a command prompt, type telnet and the IP address for the NMC (for example, telnet 10.216.253.128, when the NMC uses the default Telnet port of 23), and press ENTER.This example works for command prompt based Telnet clients. The commands may differ for different Telnet clients. If the NMC uses a non-default port number (from 5000 to 32768), you must include a colon or a space, depending on your Telnet client, between the IP address (or DNS name) and the port number. (These are commands for general usage: some clients don’t allow you to specify the port as an argument and some types of Linux might want extra commands). Enter the user name and password.Step 2 - Check if you have a Network Management Card 2 running Smart-UPS / Matrix Application, or a Network Management Card 3 running Smart-UPS Application and ensure there are no active alarms reported.Use the command to display the Network Management Card application module:Network Management Card 2 installed in a Smart-UPS uses “sumx” Application Module: Network Management Card 3 installed in a Smart-UPS uses “su” Application Module:Use the command to ensure there are no active alarms:Step 3 - If using Network Management Card 3, go to Step 4.If using Network Management Card 2: Verify the firmware revision of your Network Management Card. The firmware must be v.6.4.0 or higher, but we recommend you always run the latest available NMC firmware. To update the firmware of your Network Management Card, refer to FA156047.Use the command to display the Network Management Card firmware version:Step 4 - IMPORTANT: For Smart-UPS Ultra models with ID 1226 & 1227, the firmware of the Network Management Card must be updated to version 2.5.4.4 or later before updating the UPS firmware. Refer to FA156047 to update the firmware of the Network Management Card. Note: always download the latest NMC firmware for SUCAN application from se.com: Step 5 – Identify the correct UPS Firmware file. Use the command.Identify the "ID" number to select the proper firmware file for your UPS. For example, for a UPS with ID 1024 the proper filename will be SRTL1024UPS_xx-x.enc Download the appropriate firmware file available in the table below. The "ID" is a unique identifier for the hardware platform of your UPS. You need to use the "ID" number to make sure to select the correct firmware file. A particular UPS model may have different "ID" numbers depending on when it was manufactured, or its current firmware version. Always check the "ID" number of the UPS before starting the update, and ensure you use a firmware file with the compatible ID. If the incorrect file is used, the update will be refused, and will need to be restarted using the correct firmware file. Use the table below to determine the correct firmware file for your UPS.

Question 11

Insulation Resistance Testing and Humidity

Accepted Answer

Issue:How does humidity affect insulation resistance testing results?Product Line:Circuit BreakersEnvironment:Molded case and insulated case breakersResolution:High humidity can drastically reduce insulation resistance testing results for circuit breakers.Some equipment acceptance testing documents suggest values above 100 mega ohms and normally that is okay however high humidity can drastically reduce the results of the insulation resistance values. Below is a sample of how higher humidity can reduce the IR values, making the 100 mega ohms acceptance testing values invalid.40% humidity: breaker IR value above 500 mega ohms, typical 1 G ohm*75% humidity: breaker IR value around 10 mega ohms*95% humidity: breaker IR value around 4 mega ohms**All values above are functional and conforming. Values derived from test data on Powerpact H frame breakers in a Schneider Electric laboratory.The IEC 60947 standard, section 6.1.3.1 states that IR testing should be done below 50% humidity and states a 1 M ohm minimum IR value for a new breaker.NEMA AB-4 recommends IR values for breakers, less than one mega ohm (1,000,000 ohm) should be investigated. The Schneider Electric field testing and maintenance guide also states the same one mega ohm value, as written below.Severe environmental conditions can reduce the dielectric strength ofmolded case circuit breakers. Check insulation resistance during electricalsystem testing.To check the insulation resistance, perform the following steps:1. De-energize and isolate the circuit breaker.2. Clean the circuit breaker as described earlier.3. Using a megohmmeter with a capacity of 500–1000 Vdc, apply voltagefrom:a. Each phase-to-ground with the circuit breaker on (circuit breakercontacts closed).b. Phase-to-phase with the circuit breaker on (circuit breaker contactsclosed).c. Between each line and load terminal with the circuit breaker off(circuit breaker contacts open).4. Record resistance values. Resistance values of less than one mega ohm(1,000,000 ohm) should be investigated.

Question 12

What is the difference between PNP and NPN when describing 3 wire connection of a sensor?

Accepted Answer

Most industrial proximity sensors (inductive, capacitive, ultrasonic and photo electric) are solid state.The term solid state refers to the type of components used within the sensor. Solid state electronic components such as transistors are used to switch the output of the sensor upon detection of an object.Two specific types of 3 wire sensors are available; PNP and NPN. The difference is a result of the internal circuit design and type of transistors used. Refer to attached document for simple explanation of the two.A key point to observe is that PNP and NPN has nothing to do with whether the sensor is normally open (N/O) or normally closed (N/C), i.e. a PNP sensor may be either N/O or N/C as can an NPN be either N/O or N/C.Please note that the subject of this FAQ is specifically related to wiring PNP/NPN outputs for sensors, not to give a detailed understanding of transistor technology. However, for ease of understanding please see attached a page extracted from our Practical Aspects book, showing (in brief) transistor terminology and circuit diagrams. Further learning material regarding PNP and NPN transistors can be found online from several sources. Why two types?The selection of a PNP sensor verses an NPN sensor is determined by the nature of the circuit the device is to be used in. When used in a traditional relay type control circuit, it is normally possible to use either the PNP or the NPN type of sensor as shown below. PNP sensors tend to be more commonly used. WiringTraditional relay type control circuit; Use with a programmable logic controller (PLC).When selecting a sensor to be used with a PLC, it is very important that the sensor matches the type of PLC input card to be used.Two types of input cards exist, those that 'sink' current (also known as positive logic) and those that 'source' current (also known as negative logic). It is worth mentioning, that whilst the terms sinking / sourcing and positive / negative logic are well known in some industries, they are not always commonly used terms. It is therefore important to identify the type of sensor to be used with the PLC card based on the PLC manufacturer's documentation and / or wiring diagrams.Most common in Europe is the 'sinking' type of input, these will be used with the PNP sensor as shown below. Less common nowadays are input cards that 'source', these were popular in Asia and require the NPN type of sensor in order to operate correctly. Many modern PLC input cards can be configured and wired to be either 'sinking' or 'sourcing' although it will usually necessitate all inputs on a particular input card being configured the same. NOTE the dotted line in the following diagram is optional and may or may not be required, depending on your hardware/setup. The key wires to take note of are solid red, black and blue wires.

Question 15

What is the difference between ERMS and MMS?

Accepted Answer

Product Line: Circuit Breakers Answer: Both are methods to meet NEC article 240.87 requiring arc flash mitigation. However, the way each does it is different. ERMS (Energy Reduction Maintenance Setting): This system works differently depending on what breakers it is used with. Powerpact P/R frame; Masterpact NT/NW: The ERMS works by using an IO module to communicate with the trip unit and change the instantaneous setting to a preset value (default is 2x) when the switch is on, regardless of what the instantaneous is set to (it will revert to its setting when the switch is turned off). This requires a P or H trip unit with the blue ERMS label in the top right corner. Masterpact MTZ: The ERMS works through a control unit digital module that, when the switch is turned on, changes all settings on the breaker to preset ERMS values. MMS (Maintenance Mode Switch): This system utilizes the built in ZSI capabilities of A, P, and H trip units (only available on Powerpact P/R frame and Masterpact NT/NW) to eliminate the short time delay when the switch is on. This essentially resets the instantaneous setting to the short time setting. The short time delay is activated again when the switch is turned off.

Question 16

What are Circuit Breaker Conditions of Acceptability?

Accepted Answer

Issue:Do Conditions of Acceptability apply to UL489 listed circuit breakers?Product Line:Circuit BreakersResolution: No. Conditions of Acceptability apply to UL recognized components, but it does not apply to UL489 listed circuit breakers. (See attached for a detailed article from UL on this topic)UL Listed circuit breaker products have been investigated using applicable construction and performance requirements, and when installed in accordance with the manufacturer’s installation instructions, should provide a safe, code-compliant installation.UL Recognized components will not be compatible with all end-product equipment applications. UL’s Listing evaluation of an end product includes an investigation of the construction and performance of all installed components.Because recognized components are only intended for installation in end products whose safety is evaluated by UL separately, they may be incomplete in construction or restricted in performance capabilities. This factor precludes their safe installation by electricians or contractors in the field. UL Recognized Components have been evaluated by UL for factory installation within equipment where the component’s limitations of use are known and investigated by UL. Finally, UL Recognized Components have conditions of acceptability that describe how components can be used within end products.Examples of conditions of acceptability for a contactor may include: Component is not intended to be cycled by the operation of an automatic reset overloadTerminals are to be factory wired only Suitability of the connections, including spacing between factory connectors, must be determined once installed within an end productShort circuit capability may need to be evaluated in the end-use applicationSpacing from exposed live metal parts to the enclosure must be evaluated in an end product See attachment for full UL article on this topic.
