Symmetra LX

Remove the faulty power module

  1. Identify the faulty power module using the display interface.
    1. The fault and diagnostic menu will identify any failed power modules by their location (L1 - L5).
  2. Remove the front cover of the UPS and locate the faulty power module. The front cover is removed by pressing both latches inwards. The cover will open easily.
    1. Power modules are installed on the left hand side of the system.
    2. The bays are labeled L1 - L5 (from top to bottom).
    3. The display interface should display a "Power module quantity decreased" message.
  3. Loosen the captive thumbscrew located an inch to the right of the power module's fan.
  4. 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.
  5. Grab the handle and lift up on the module while pulling out.

Install the replacement power module

  1. Unpack the replacement power module from its packaging.
  2. Visually inspect the connector, located on the rear of the power module. Look for any signs of damage, anything broken, bent pins or nonconformance. If there is a problem with the replacement module, do not continue. Contact Schneider Electric technical support. The connector itslef in the power module is designed to be a bit loose/wobbly. This is so it can align with the Symmetra LX backplane connector.
  3. Visually inspect the backplane inside the Symmetra LX Cabinet. Look for any signs of damage, anything broken, bent pins or nonconformance.
  4. Insert the replacement power module into the slot and slide it back until it is fully seated.
  5. Grip the thumbscrew, located just to the right of the power module's fan, and lift up on it to engage the latch.
  6. 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.
  7. Confirm that the UPS recognizes the power module. The display interface should display a "Power module quantity increased" message.
  8. Ensure that there are no faults registered by the system. If so, contact Schneider Electric technical support.
  9. Re-install the front cover of the UPS.
