CAUTION:
To protect exposed pins, please place the attached dust cover

The following sections detail the connectors used when installing the DSM300.
DC Power Connection
The DSM300 is intended for use on boat’s DC power systems rated from 10.7 V to
32 V.
The power connection to the unit should be made at either the output of the
battery isolator switch or at a DC power distribution panel. Power should be fed
directly to the DSM300 via its own dedicated cable system and protected by a
thermal circuit breaker or fuse on the red (positive) wire that is installed close to
the power connection.
DC power is connected at the 3-pin POWER connector on the unit’s connector
panel. The connector (viewed from the outside) and pin functions are shown in
the following diagram and table.
