Make a list of all inputs and outputs to be wired to the COI and take note of the output channel ratings and
functions as shown in Figure 8. Ensure loads are wired to the appropriate channel for the functionality
required.
All 25A channels have the option to alarm on detection of external voltage, useful for circuits such as Bilge
Pumps with an external or “automatic” supply from a float switch. This feature reduces wiring by allowing
control and feedback from a single wire. See Figure 9 for a Bilge Pump wiring example.
For loads with a continuous current exceeding max channel current it is possible to parallel output channels
up to 80A for OUT-H connector and 100A for OUT-L connector (do not parallel outputs between connectors).
