1. Verify that the AC circuit breaker is OFF.
2. Strip 5⁄16'' (8 mm) of the DC wire insulation.
3. Insert the DC conduit into the DC-side opening. Make sure the conduit is firmly attached to the
inverter enclosure and sealed properly.
4. Connect the DC wires from the PV installation to the DC+ and DC- terminal blocks, according to the
labels on the terminals:
a. Insert a flat blade screwdriver into the square opening at the top of the terminal block and press
to open clamp mechanism.
b. Insert the wire into the round opening and release the screwdriver to spring back and clamp the
wire. Check that the wire is fully inserted and cannot be pulled out easily.
CAUTION!
Ensure that the Plus (+) wire is connected to the Plus (+) terminal and that the Minus (-) wire is
connected to the Minus (-) terminal connector.
Veillez à ce que le câble Plus (+) soit connecté au terminal (+) et que le câble Minus (-) soit
connecté au connecteur terminal (-).
NOTE
For systems with three PV strings or more, fuses may need to be installed in both the positive
and negative conductors as required by Article 690.35(B). For more information, refer to the
