Connect the Power Wires
WARNING: Shock Hazard
The solar modules can produce open-circuit voltages in excess of 100 Vdc when in
sunlight. Verify if solar input breaker or disconnect has been opened (disconnected)
before connecting system wires.
Connect terminals by following below steps (Refer to diagram above):
1. Make sure that the system input and output disconnect switches are both turned
off before connecting power wires to the charger. There are no disconnecting
switches inside the charger.
2.
Make 4 power wires first. Remove insulation sleeve 10.5mm and the conductor
should be plated Tin. Refer to the chart below.
3. Pull all wires into the wiring box.
Sense wires can be inside the conduit with the power conductors. It is easier to pull
RTS and Sense wires before the power cables.
WARNING: Risk of Damage
Be sure that the battery connection is made with correct polarity. Turn on the battery
breaker/disconnect and measure the voltage on the open battery wires BEFORE
connecting to the controller. Disconnect the battery breaker/disconnect before wiring
