Torque settings for NSX MCCB power terminals are below: 100amp and less rated frames = 10Nm 125-250amp rated frames = 15Nm 400-630amp rated frames = 50Nm These are for the top and bottom power terminals

Internal Arc Classification IAC A-F, A-FL and A-FLR are defined in IEC 62217-200 and help to define internal arc performance of medium voltage or high voltage switchgear. The following definitions are described as: A switchgear installation in rooms with access for authorized personnel, closed...

The maximum earth loop Impedance figures can be found on the attached pdf files. 16A to 250A The standard MCCB's used for ratings of 16A to 250A with part numbers beginning with "MGP..." are identical to the NSX with thermal magnetic trip units. 400A & 630A The standard MCCB's used for ratings...

A negative kW reading is usually due to one of 2 things The Current transformers (CT's) have been fitted onto the cable or busbar the wrong way round. The P1 side of the CT should be towards the supply and the P2 side of the CT should be towards the load. Alternatively, if the CT is fitted...

The software to program the Modicon M241 is EcoStruxure Machine Expert (former SoMachine). In order to install this software you need to download "Schneider Electric Software Installer" from the next link:...

EcoStruxure Facility Expert TM evolution Schneider Electric is improving and enhancing your experience by transitioning from EcoStruxure Facility Expert to a new solution ecosystem. Here a substitution table comparing legacy Facility Expert subscription type vs. new solution proposed:...

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...

Issue You wish to upgrade your Network Management Card's (NMC) firmware or have been instructed to. You have a device such as a Smart-UPS, Smart-UPS Ultra, Easy UPS On-Line, Easy UPS 3-Phase, Rack PDU, AV unit, or environmental monitoring unit with an embedded NMC that you wish to upgrade. You had...

Issue: What is an electrical "ground loop" and how does it affect my equipment? Environment: Ground loops can occur in any situation where multiple electrical devices are interconnected, especially when those devices are powered from different sources or located in different places with varying...

In order to identify in our code which M172 model we are using we need to use the two (2) internal variables located in "Operators and blocks". The variables are Par_POLI (Polycarbonate code) and sysMSK (Mask number). If a M172 with 28IOs or 42IOs is connected then the variable "sysMSK" is equal to...

There is often confusion between the in-phase and the In-sync features of ASCO transfer switches. It is important to understand the difference between these features especially during the process of selecting transfer switches for different applications. In-Phase The in-phase monitor is a feature...

Issue: How do I remember the relationship of voltage, current and resistance in an electrical system? Environment: N/A Solution: Voltage (unit of measurement - volt) is like the water pressure in the pipe. When you turn on a faucet, the water pressure makes the water flow out. Similarly, voltage...

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...

Issue: What is Power Factor Correction (PFC) - Does it help conserve energy? Answer: Explanation 1: Power Factor Correction (PFC) doesn't directly reduce the overall electric consumption of a device or system, but it does play a role in optimizing the efficiency of electrical systems, which can...

Register the Easy UPS with APC by Schneider Electric customer support. This is a one time process required to be done only during initial installation. The Easy UPS output cannot be turned on without successfully completing registration process. After successful completion of the registration...

For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC 50Hz while the UK used 240VAC 50Hz. In 1994, the European Union state members decided to proceed with a voltage harmonisation at 230Vac. This meant that consumers could be sure that a product...
