Connect the output cable to the battery bank(s) using
the suggested wiring diagrams for guidance.
Remember to observe the correct polarity.
RED to PO and BLACK to NEGATIVE –
Where a battery monitor
is fitted
If your electrical system is fitted
with a digital battery monitor, it
will be driven by a shunt which is
typically installed close to the
batteries.
One side of the shunt is
connected directly to a battery
terminal.
All other connections are made
to the opposite side of the shunt,
or a busbar associated with it.
The shunt is most usually
connected in the negative line.
When wiring the D400 to a
system fitted with a shunt,
observe polarity and connect the
appropriate D400 output
cable to the non-battery side of
the shunt.
Again observing polarity, the
other D400 output cable should
be made directly to the battery
terminal.
The D400’s output will now pass
through the shunt and the
battery monitor will display a
reading.
If the shunt is bypassed by
connecting both positive and
negative output leads from the
D400 directly to the battery, the
meter will fail to ‘see’ the D400,
and register no output.
The D400 is fitted with 4.5 mm² output fly leads
