3. Select CONTROL then START BATTERY TEST.

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 72.
NOTE DO NOT DISCONNECT the electronics module while the UPS is in Battery mode.
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 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.
2. Parallel configurations only. Disconnect the redundant signal cable(s) from the
UPS. For the location of the redundant signal cable, see Figure 36 on page 47.
3. Remove the UPS front cover and the electronics module and set them aside (see
Figure 59):
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.
NOTE Treat the electronics module with care to avoid damaging the fans, connectors, or internal circuitry.
