Mounting
Mount the DBM20A with its wires facing downwards close to the Aux Battery on metal auto-body panel
to provide the best cooling. Do not mount close to hot engine parts such as exhaust or turbo charger.
The DBM20A will typically warm to around 40°C depending on application.
If the DBM20A experiences extreme heat due to inappropriate mounting position, the system will do a
safety shut-down.
Wiring extension
If extension of the power wires red/black/blue is needed use 4mm
2
wires for up to 1 additional meter, for
up to 3 additional meters use 6mm
2
and if needed longer use 10mm
2
(copper cross section – not
external insulation size) wires. Use 10mm2 wires to extend wires if DBM20A is mounted in a Trailer.
