Prerequisites

Procedure
Step 1 Ensure that the TN system is reliably grounded, and that the main ground cable of the module
is reliably connected.
After removing cables, wrap exposed terminals with insulation tape and do not block cable
labels. If cable labels are blocked, cables may be connected incorrectly.
Step 2 Turn off the battery switch, or remove the wiring terminal between the battery pack and the
faulty UPS.
Step 3 Open the front door of the cabinet. Remove the protective cover from the maintenance bypass
switch, and manually turn on the maintenance bypass switch (the UPS will automatically
transfer to bypass mode and generate an alarm indicating that the maintenance bypass switch
is turned on).
Step 4 Turn off the corresponding UPS input and output switches. Use a multimeter to check
whether the UPS input and output terminals and battery terminals are disconnected.
Step 5 Remove the rear cover from the UPS, and remove the input and output power cables, battery
cable, and signal cable.
