5 INSTALLATION
5.4 BROWN wire — Output load Positive
The BROWN wire should be connected to the output load’s
positive terminal. This should be a maximum of 1 m (3.3') in
cable length from the DPS. Appropriate size fuses should be used
as per the specifications table on page 4

5.5 BLACK wire — Common Ground
The BLACK wire should be connected to a ground point that is
common to both the start battery and the load. This point may
be on the chassis of the vehicle or on the chassis of the trailer
depending on your installation requirements.

5.6 GREEN wire — Optional External LED
The GREEN wire is provided to optionally connect an external
indicator LED which can be mounted away from the unit (for
example on the vehicle’s dashboard). The DPS will limit the
current supply by the GREEN wire to 6 mA so a standard green
LED can be connected directly between the GREEN wire and the
common ground. An LED with a series resistor can also be used
but the resistor value should be less than or equal to 1000 Ohms
(an LED with a built-in 1000 Ohm series resistor is typically
referred to as a “12 Volt LED”).
Connect the positive lead of the LED to the green wire, and the
negative lead to the common ground.
This LED will illuminate constantly when the DPS is supplying
power, it will flash a fault code if the DPS has detected an error.

5.7 Earth Isolation
If the DPS is installed on a vehicle fitted with an earth isolation switch, the BLACK wire must run to
chassis earth/ground and NOT the supply battery’s negative post. This ensures that the DPS is also
disconnected when the isolation switch is activated.
