2.2 USM2 Installation, XM2 , continued
3. Setup the USM2 for proper operation (see Section 3, Configuration):
a) Before reinstalling the Inverter Module, set the two DIP switches, SW1 and SW2, and the two Jumpers,
JP1 and JP2, to the proper configuration settings for the status monitoring interface, as per Table 3-1.
Always verify USM2 configuration especially after upgrading or modifying the XM2 Series 2 Power
Supply.
4. Carefully reinstall the Inverter Module:
a) To re-seat the Inverter Module: align the metal shield in the upper and lower card-guides. Using ONLY
the Inverter Module’s handle (
absolutely apply no pressure of any kind to the front panel) firmly drive
the module back into the connectors. The connectors are designed to be engaged with reasonable force.
The thumbscrews are not intended to aid in making these connections, but to secure the Inverter Module
to the chassis.
b) IF the Inverter Module is correctly seated, the front panel Smart Display will activate, and the “Inverter
Disconnected Alarm” will NOT be active.
c) Retighten the thumbscrews. ONLY tighten by hand, Do not use tools to tighten the thumbscrews.
d) Reconnect all the cables (TMPR, XPDR, and SYS COM) as needed to the Communications Module.
e) Verify that the battery breaker is OFF, reconnect the battery input, and the temp probe cables, and then
finally switch ON the battery breaker.
