Connecting the Strings to the Inverter
Figure 20: PV connection
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(s) is connected to the (+) terminal and that the Minus (-) wire is
connected to the Minus (-) terminal connector.
Veillez à ce que le câble(s) Plus (+) soit connecté au terminal (+) et que le câble (-) soit
connecté au (-) terminal.
NOTE
For systems with four PV strings or more, fuses may need to be installed in
both the positive and negative conductors as required by NEC Article 690.9.
