WIRE CONNECTIONS
DC Wiring
The Inverter uses DC brass battery terminals with 8M x 1.00 stainless steel threaded studs. You can access
the terminals by removing the four screws that attach the DC cover plate, and pulling it off.
Red terminal=battery positive
•
Never install extra washers or any other hardware between the terminal mounting surface and the
battery cable lug—the connection must be direct and secure.
•
For the Inverter model OBX-IC2024S-120/60, a 175-amp DC breaker is recommended. If a
•
DC fuse is used, it should be a Class T fuse and must not exceed a rating of 300 amps.
•
Always install breakers or fuses on the positive battery cable.
•
It is recommended to twist the positive and negative conductors around each other during
installation. This is to reduce EMI (electromagnetic interference) emissions.
•
Use torque values from the chart below for tightening battery connections and Inverter DC connections.
