receive power from the UPS.
4. Open the UPS front door(s).
5. Remove the retaining brackets for the fuse holder containing DC fuses F001, F002, and
F003. See Component Overview illustration in this Installation Guide for location of fuse
holder.
6. At the utility input, switch on the input power to the Maintenance Bypass Panel.
7. At the Maintenance Bypass Panel, set the UPS AC disconnect switch to “ON”. The UPS
display should show “System type xxkVA xxxV”.
8. Within 20 seconds, the display should show **Stand-by** and an audible alarm should
sound.

phase rotation is incorrect. The phase rotation must be A, B, C and clockwise.
10. When the audible alarm stops, press the green “ON” button located inside the UPS front
door. The display should show “Normal operation load power xx%”.
11. Open DC fuse holder (F001, F002, F003). For location of DC fuse holder, see Component

of the fuse holder. Make sure that the fuse locking tabs are aligned in the slots on the fuse
holder. See DC Fuses illustration.
13.Press each fuse into place. The fuse will “click” into place when it is locked in correctly.
14. Using an open palm, close the fuse holder.
WARNING
Some units have been programmed at the factory for “autostart”. If programmed for “autostart”,
the unit will turn on when utility (AC line) is applied (after a 60-second delay). For more
information or to change this feature, see the User Guide.
Before continuing, read the warnings on page 2 of this Installation Guide.
CAUTION!
No load should be connected when this procedure is carried out.
NOTICE!
One or more alarms may occur. If the alarm(s) persists for more than 20 seconds, refer to the
“Alarms” section of the User Guide. If the unit activates a “battery monitor alarm”, you should set
the user parameter “battery monitor reset” to “ON”
