DPM Hardware Installation and Quick Start Guide
Confi guring the network prior to installation is recommended to allow the
transponder communication to be verifi ed while the technician is on-site
eliminating the need for a second visit if there are any problems.

a. Turn the XM2-300HP battery circuit breaker off.
b. Disconnect the battery from the front of the XM2-300HP.
c. Disconnect the temperature sensor.
d. Loosen the three inverter module thumbscrews, and slide the inverter
module out of the power supply.
e. Remove the existing communications panel from the inverter module.
