7.2 Installation / Replacement Procedure in XM2 Power Supplies
If the XM2 CableUPS has been shipped without a DM3X Transponder, or the existing module requires removal and
replacement, do so via the following procedure:
1. Switch OFF the Inverter Module battery breaker.
2. Disconnect the battery input and temperature sensor cables from the Inverter Module, followed by the tamper, RF
and battery sense cables if a transponder is currently installed.
3. Loosen the Inverter Module thumbscrew and (if applicable) the two transponder thumbscrews.
4. Slide the Inverter Module out of the power supply.
5. Disconnect the ribbon cable attached at the back of the Inverter Module.
6. If the Inverter Module is equipped with a transponder, remove it by loosening the two Phillips captive screws.
