Replacing the Electronics Module

You can easily replace the electronics module without turning the UPS off or disconnecting the load. Battery
mode is not available and your equipment is not protected; however, the utility power continues to be filtered
passively by the UPS.
If you prefer to remove input power to change the electronics module, see "Individual UPS Shutdown" on
page 102.
NOTE
To replace the electronics module:
1. Standalone UPS configurations only. Transfer the UPS to Bypass mode. Continue to Step 3.
Parallel for capacity configurations only. Transfer the UPS to Bypass mode. The CAN bus remains
energized.
Parallel for redundancy configurations only. No mode transfer is necessary. If the UPS is operating in a
parallel for redundancy configuration when its electronics module is removed, the load automatically
transfers to the remaining UPSs. The CAN bus remains energized.
NOTE
2. Parallel configurations only. Disconnect the redundant signal cable(s) from the UPS. For the location of
the redundant signal cable, see Figure 63 on page 75.
3. Remove the UPS front cover and the electronics module and set them aside (see Figure 83):
To remove the UPS front cover, grasp the fingergrips on both sides of the cover and pull the cover
forward firmly. Unplug the LCD cable connecting the back of the control panel to the electronics module.
To remove the electronics module, remove the electronics module locking screw at the top left of the
electronics module and retain. Grasp the ring handle at the middle of the module and pull the module
slowly out of the cabinet. Pull firmly to unseat the connectors. Use two hands to support the module.

DO NOT DISCONNECT the electronics module while the UPS is in Battery mode.
Disconnecting the control panel from the electronics module automatically transfers
the UPS to Bypass mode. However, transferring the UPS to Bypass mode manually
BEFORE disconnecting the control panel provides extra protection to the
electronics module and is recommended.
Treat the electronics module with care to avoid damaging the fans, connectors, or
internal circuitry.
