7.9.11 Connecting the Battery Heater Mat Controller
Power to the heater mat is provided via a customer-supplied controller plugged into the power
outlet inside the enclosure. A cable (Alpha p/n 875-627-22) connects the controller to the ENV
(Environmental) connector on the DSM3x and DPM. The connection procedure is shown below.
1. Connect the 4-pin connector
from the controller cable (Alpha
p/n 875-627-22) into the base of
the Heater Mat Controller.
2. Plug the controller into
the power outlet.
4. Plug the 6-pin connector
into the ENV connector.
3. Plug the Heater Mat into the controller.
