Resolution

The following text describes the recommended procedure for use when replacing power modules. Please refer to the section that pertains to your particular model.

Symmetra LX

1.) Remove the faulty power module.

Identify the faulty power module using the display interface. The fault and diagnostic menu will identify any failed power modules by their location (L1 - L5).
Remove the front cover of the UPS and locate the faulty power module. Power modules are installed on the left hand side of the system. The bays are labeled L1 - L5 (from top to bottom).
Loosen the captive thumbscrew located an inch to the right of the power module's fan.
When the screw is as loose as it can be, the latch that it is attached to should move down slightly to unlock the module. If the latch does not move down by itself, pull it down.
Grab the handle and lift up on the module while pulling out.

2.) Install the replacement power module.

Unpack the replacement power module from its packaging.
Visually inspect the connector, located on the rear of the power module, for any signs of damage or nonconformance. If there is a problem with the replacement module, do not continue. Contact Schneider Electric technical support.
Insert the replacement power module into the slot and slide it back until it is fully seated.
Grip the thumbscrew, located just to the right of the power module's fan, and lift up on it to engage the latch.
Hold the latch up and tighten the thumbscrew. The thumbscrew should be as tight as you can get it without the use of a tool.
Confirm that the UPS recognizes the power module. The display interface should display a "Power module quantity increased" message.
Ensure that there are no faults registered by the system. If so, contact Schneider Electric technical support.
Re-install the front cover of the UPS.
