Installation Guide

• Connect the negative wire from your lights, pumps, and other accessories to the system by
connecting directly to the negative bus bar using 4mm ring terminals. If you have a larger load
circuit (over 30 amps) we recommend to connect the negative directly to the Main negative
Bar.
Note: No negative connections are to be direct to the battery or on the battery side of the shunt as this will
result in incorrect reading on the Simarine system.
Solar Connection
• If you are fitting either fixed solar panels or portable solar panels via an Anderson plug,
connect the solar wiring directly to the DC2DC+ as the MPPT regulator is inbuilt. Cabling
should be sized to the rating of solar installed but as a minimum 4mm2 cable is to be used
with 6mm ring terminals connecting to the solar terminals on the DC2DC. Ensure the panels
are disconnected or covered from the sun during connection to the DC2DC.
Connect negative wire from
accessories to this busbar.
