Vcm100 Screen (Drain) Wire Extension; Circuit Breaker And Fuse Ratings - Raymarine CYCLONE Installation Instructions Manual

VCM100 screen (drain) wire extension

The screen (drain) wire can be extended for longer cable runs between the VCM100 and your
vessel's RF ground system.
Extensions to the screen (drain) wire should use an 8 mm braid or AWG 10 (5.26 mm
cable.

Circuit breaker and fuse ratings

Battery isolator switch, thermal breaker, and fuse ratings.
All power connections between the VCM100 and its power source must be protected by a thermal
circuit breaker or fuse, fitted close to the power connection. The connection from the output of the
VCM100 to the digital radar does not require a fuse or circuit breaker.
If you do not have a thermal circuit breaker or fuse in your power circuit (fitted to the DC distribution
panel, for example), you MUST fit an in-line breaker or fuse to the positive wire of the power cable.
The following table provides suitable ratings for battery isolator switches, circuit breakers, and fuses.
