2.8 Installing the XM3 Power Supply
Installation Procedure:
1.
Before installation, inspect the power supply for damage or loose connectors.
2.
Place the XM3 Power Supply on the equipment (top) shelf of the enclosure.
3.
Switch the BATTERY BREAKER
1
on the front of the power supply OFF. This prevents the inverter from starting
when the batteries are first connected to the power supply.
4.
After verifying that the batteries, battery connections, and battery cables are connected properly, plug the battery
cable connector from the battery string into the power supply’s BATTERY INPUT connector
2
. The connector is
keyed and color-coded to fit in only one direction.
5.
Plug the Remote Temperature Sensor into the TEMP PROBE
3
connector located on the Inverter Module
assembly on the front of the power supply.
6.
If applicable, plug the optional Local/Remote Indicator lamp (LRI) cable into the LRI connector
4
.
7.
If you are installing a Tamper Switch (TMPR SW), plug it into the 2-pin TMPR connector, and plug the transponder
cable into the transponder TMPR connection
5
.
8.
Plug the connector from the SPI into the power supply’s OUTPUT 1
6
. If the enclosure has the optional AC
Indicator (ACI) lamp, plug the connector from the SPI into the ACI and the connector from the lamp into the power
supply’s OUTPUT 1. If the PIM option is installed, connect a second SPI to OUTPUT 2
7
. Make sure that the SPI
“ALT/ON” switch is in the ON position.
9.
If the installation includes a Module Retaining Cable option, attach the end of the cable to the hole provided at the
top, rear, center of the enclosure. Thread the cable through the power supply handle and clip it back on itself.
10. The installation is complete. DO NOT apply AC power to the power supply or switch the Inverter Module’s
BATTERY BREAKER ON. Refer to the XM3 Series Power Supply Technical Manual
(Alpha p/n 017-882-B0)
for
Start-up and Test procedures.
Check the polarity and voltage of the battery cable connector with a voltmeter before proceeding. Connecting
the battery string or strings to the power supply with incorrect polarity may cause a short-circuit, and possible
equipment damage. Check all battery connections for proper installation. For complete battery installation
procedures, see the “Battery Installation” section in this manual.
