Installation
Before applying power, verify Power Supply rating is matched to AC input utility. Verify a low-resistance
ground is installed in accordance with your local electrical regulatory authority.
NOTE:
Note: For existing LRI installations, use LRI adapter kit, p/n 875-952-20.

2.2.8 Power Module Configuration and Installation Procedure
Batteries are an important part of the Power Supply. Properly install and test all batteries, battery
connections and battery cables before you connect them to the Power Supply.
CAUTION!
1. Route the Local/Remote Indicator cable down through the opening in the left side of the shelf and
back up through the opening in the right side of the shelf and connect.
2. After wiring battery cable kit, battery sense cables and PTS as shown in Section 2.2.2, Battery
Installation Options and Wiring Diagram, verify DC breaker is OFF, then connect battery cable to
Inverter Module.
3. Connect the Smart AlphaGuard wire harness to Smart AlphaGuard port.
4. Connect Precision Temperature Sensor to Inverter Module.
5. Connect transponder, RF Input cable, and the tamper switch (if installed). Refer to Section 2.2.7.1,
DOCSIS Status Monitor Front Panel Connections for communication module connections.
6. For new installations, skip to step 10.
7. For upgrading existing sites, install Service Power Supply (see Service Power Supply documents)
and remove existing Power Supply.
8. Thoroughly inspect output connectors for abnormal heating or damaged housing; replace if
necessary.
9. Verify SPI (16) switch is in “ALT” position.
10. Connect the SPI (network load) to the Output 1 connector.
11. Connect the second isolated load / auxiliary load (i.e., fan) to the Output 2 connector.
12. Turn on AC breaker (located on enclosure) and verify correct (per unit’s nameplate voltage) utility
voltage at outlet; if correct, plug in line cord to the utility outlet. For XM3-918D-HP models, the utility
voltage may not match the nameplate voltage when switching between 120V and 240V.
13. Turn battery breaker ON. For XM3-918D-HP models, select the Input Voltage Setting by pressing
ENTR.
14. Toggle SPI switch to ON.
15. Verify no alarms are present after power up initiation (it may take up to 60 seconds for alarms to clear;
APPs alarms may take longer). Alarms may be verified on the LCD display or Alarm LED.
