3.2 AC Input Voltage Reconfiguration
The input voltage on many models (XM2-915, XM2-918HP, XM2-910, XM2-906HP and XM2-
1350) can be reconfigured from 120 to 240Vac utility input or from 240 to 120Vac utility input,
depending upon utility input powering requirements.
Tools Required:
• #2 Phillips head screwdriver
• Flat-blade screwdriver
Supplies Required:
240Vac 15A line cord (NEMA 6-15P, P/N 874-540-22)
240Vac jumper (744-281-21).
Procedure (120 Input to 240Vac Input):
1. Completely shut down the XM2 power supply.
Remove all utility and battery power. All
connections and cables must also be removed
from the XM2 power supply.
2. Verify the enclosure system wiring before
proceeding with power supply modification.
Refer to the appropriate enclosure installation
instructions.
3.
Replace the 120Vac 20A line cord (NEMA 5-20P)
on the XM2 power supply input line cord with
a 240Vac 15A line cord (NEMA 6-15P). Verify
proper wiring and ground on the new plug.

240V, 15A Plug and Receptacle
To avoid exposing the technician to potentially lethal voltages, remove all power from
the power supply; unplug the power supply from the AC power source, remove all
front panel connections (i.e., N+1) and disconnect the battery connector.
Only qualified personnel should reconfigure the input voltage. Before modifying the power supply,
always consult local electrical codes for proper wiring procedures.
ATTENTION:
When the AC input voltage reconfiguration is complete the voltage rating of both the high-magnetic
breaker and enclosure receptacle must match the input voltage.
