Step 3
Remove the rear cover from the bypass cabinet.
You are advised to remove the side panel from the bypass cabinet before connecting cables.
Step 4
Remove the copper bars between the mains and bypass input wiring terminals. (Perform this
step only when the mains input and bypass input use different power sources.)
Properly keep the removed copper bars and bolts.
(Optional) If copper bar protective covers are installed for the bypass cabinet, remove the protective
covers and then the connecting copper bars. The protective covers need to be reinstalled after the
connecting copper bars are removed.
Step 5
Connect a ground cable to the UPS.
If you do not ground the UPS as required, electromagnetic interference, electric shocks, or fire
may occur.
Connect cables from bottom up in this sequence: bypass input power cables, output power
cables, mains input power cables, and battery input power cables.
When connecting cables, tighten bolts from inside out to secure cables.
Before connecting cables, ensure that all UPS input switches are turned off. Paste warning
labels to prevent others from operating the switches.
Connect the input power cables to the UPS before connecting power cables to customer
equipment.
