1.10 Circuit breaker and fuse ratings
It is recommended that power is fed directly to the VCM100 via its
own dedicated cable system and MUST be protected by a thermal
circuit breaker or fuse, fitted close to the power connection, then run
power from the output of the VCM100 to the digital radar, (
the
connection from the output of the VCM100 to the digital radar does
not need any fuse or circuit breakers connecting
). Refer to the table
below for isolator switch, circuit breaker or fuse value ratings. Check
and ensure all terminal connections are clean.
CAUTION:
If you do not have a thermal circuit breaker or fuse in your power
circuit, e.g. fitted to the DC distribution panel, you MUST fit an in-
line breaker or fuse to the positive lead of the power cable.
