Clean the condenser filter and test the LCDI plug
The condenser filter traps large items that may fall into the ducts. Periodically check and clean the filter
to prevent damage to the condenser. While power is off, test the LCDI plug for proper operation.
1. Turn off the equipment and unplug it from its
electrical outlet.
2. Remove the condenser air intake duct from the back
of the equipment.
3. Clean the filter (inside the air intake duct) using your
hand or a dry cloth.
4. Press the TEST button on the LCDI plug. The
POWER LED should go off.
5. Press the RESET button on the LCDI plug. The
POWER LED should come on.
Clean the cabinet
Turn off the equipment and unplug it from its electrical outlet. Use a moist rag to wipe down the cabinet.
Caution: Do not clean the surface with thinners, alcohol, polishing powder, alkaline
detergent, acid, or an abrasive brush. Using these items will damage the cabinet.
Update the main control board firmware
Occasionally, new firmware becomes available which may add new features. Firmware is available for
download through the APC software/firmware downloads page, www.apc.com/tools/dowload.
You will need a computer with a serial port, a null modem serial cable, and a terminal emulation program
that can use the xmodem protocol.
