2.4.2.1 Protection

WARNING
• Each power connection to the DCR100 must be individually protected with
a fuse or circuit breaker which is sized to match the wire between the
breaker/fuse panel and the DCR100, and between the DCR100 and the
load. This fuse or circuit breaker must be sized to be no larger than 10A.
For example, if you are using all six channels of the DCR100, there must
be 6 circuit breakers and a separate power lead from each circuit breaker
to the Px terminal for each channel.
The power "Px" terminals must always be connected to the circuit-breaker protected power
source (which can be wither 12VDC or 24VDC), and the load "Lx" terminals must always be
connected to the power terminal on the load. The other terminal of the load must be connected
to vessel ground. This figure shows the connection of a power and load connections to the
DCR100.
