Power Module Installation
XM Series power modules are placed in the lower-right compartment of PME
enclosures; the upper-right compartment of PWE, UPE and UPE/M enclosures. The
enclosure's lid lifts and the door(s) can be removed. (Refer to the Module and Battery
Placement drawings located at the back of the manual).
Procedure:
1. Set the XM Series power module on the enclosure’s shelf.
2. Plug the connector from the SPI (Service Power Inserter) into the module's "AC
OUTPUT" connector. Make sure that the SPI’s "ALT/ON" switch is in the ON
position. NOTE: If the installation includes an ACI lamp option, plug the lamp's
connector into the module's "AC OUTPUT"; then, plug the SPI into the second
connector on the ACI.
3. Switch the module's "BATTERY" circuit breaker OFF. This will prevent the inverter
from starting when the batteries are first connected to the unit. Note: Do not switch
the battery breaker ON until the power module is running on utility AC.
4. Plug the quick connects from the battery cable into the module's "BATTERY"
connector. The connectors are keyed and color-coded to fit in one direction only.
5. If an optional LRI lamp (Local and Remote Indicator) is included, plug its cable into the
module's "REMOTE INDICATOR LAMP" connector.
6. If remote alarms are included in the installation, the cable should be plugged into the
module's "STANDBY STATUS RELAY connector. White (1) is configured common;
Red (2) is configured “normally open” (contacts close when alarm is present). The
contact can be configured “normally closed” (contacts open when alarm is present) by
moving the wire located on the module's back plane board from P104 to P105.
7. If the module is equipped with a Remote Temperature Sensor, plug the connector into
the RTS port (above the data port) located on the main circuit module assembly.
Route the sensor end of the cable into the battery compartment (see section 6.7).
NOTE: VERIFY BATTERY CHARGE VOLTAGES (SECTION 6.9) BEFORE STARTING THE
POWER SUPPLY.
