Pre-Service Connection Procedure
4. Connect the battery cables to the battery terminals
(connect temperature sensor ring lug to the Negative ( –)
battery terminal at this time) and the enclosure sensor
into the clip on the front edge of the Power Supply
shelf. Tighten the terminal hardware to the battery
manufacturer’s recommended torque settings.
5. Insert the (+) and ( –) power leads for the optional Local/
Remote Indicator (LRI) cable as indicated in Fig. 1.
Tighten to 7.0 lbf•in / 0.8Nm.
6. Make the following DM3 connections:
a. RF Cable to DM3 RF Connector. Tighten to 10in-lb ± 1in-lb
b. Environmental cable (e.g., PoE control, Battery heater
mat control)
c. Tamper switch cable into TPR connector
7. Connect the power leads from the SPI (network load) to
the Output 1 connector as indicated below; Black to ~,
White to N. Tighten to 7.0 lbf•in / 0.8Nm.
8. Connect an auxiliary load (e.g., fan) to the Output 2
connector (optional)
;
Black to ~, White to N
.
Tighten to 7.0
lbf•in / 0.8Nm.
9. Turn on AC breaker (located on the enclosure) and verify
the correct (per unit’s nameplate voltage) utility voltage is
present at the outlet before plugging the XM3-200HP line
cord into the utility outlet.
Turn-Up and Test
1. Plug the XM2-300HP line cord into the utility outlet.
2. The power supply will perform a “display test” and verify
configuration for the power supply. After the initial display
test, a “No Batteries” alarm message appears in the Smart
Display because the battery switch is off. The green output
LED remains off and the red alarm LED continues to flash
while in this alarm state.
Connect the battery to the Battery Input connector.
4. Set the Inverter Module’s battery switch to the ON position
(1).
5. Verify no alarms are present (it may take up to 60 seconds
for alarms to clear).
6. Perform a self-test by simultaneously pressing the DOWN
arrow key and ENTER key. Wait for self-test completion
before proceeding. To manually exit self-test,
simultaneously press DOWN arrow and ENTER key.
7. Perform the live inverter test procedure:
a. Turn AC input breaker OFF.
b. Verify XM2-300HP transfers to “Inverter” mode.
c. Turn AC input breaker ON.
d. Verify XM2-300HP transfers back to utility.
8. Set the Service Power Inserter (SPI) toggle switch
to the ON position (Fig. 2).
9. Verify no alarms are present.
10. Secure the enclosure.
11. The unit is now in service. For additional information visit

1. Verify Service Power Inserter (SPI) toggle switch is set
to the ALT position (Fig. 2).
2. Verify the battery switch is set to the OFF position on
XM2-300HP (0).
3. Loosen the captive fasteners and remove the Inverter
Module from the chassis. On the DM3, locate and
examine J12 on the DM3 module to verify the jumper
connects pins 2 and 3 (see Fig. 5). After verification,
reinsert and secure the Inverter Module.
