5 INSTALLATION
5.1 INSTALL LOCATION
Mount the Battery Charger to a flat surface in close
proximity to the auxiliary battery and away from any
heat sources. The BCDC1220(-IGN) has five wires and
should be installed as described over the following
pages.
The Charger operates in any orientation (but it is
recommended that the front of the decal be visible).
Mount using the 4 mounting tabs provided on the
heatsink with suitable M6 fasteners.
NOTE: The Unit will operate optimally below 55°C
(130°F) with good airflow. At higher temperatures the
Unit will de-rate output current.
NOTE: Appropriate connections must be made to the
wires with a continuous current rating of at least 20 A
for the BCDC1220(-IGN). Failure to do so may cause
damage to the Unit and vehicle.
