PV Grid-tied Residential Inverter and Integrated AC/DC Disconnect

Installation and Operation Manual

WARNING

Ensure the main circuit breaker at the utility service panel is

switched off before connecting to the AC terminal block.

AVERTISSEMENT

S’assurer que le disjoncteur principal du panneau de service

public est déconnecté avant de le connecter au bloc de jonction

en CA.

To wire the inverter/disconnect unit to the main utility grid, follow these

steps.

1. Ensure the disconnect switch is in the OFF position.

2. Route conduit from the main breaker panel to the AC side of the

disconnect.

3. Insert a tting into one of the AC knockouts on the bottom of the

disconnect and fasten securely with a locking nut. Refer to Figure 4-2

for knockout locations.

4. Route the AC conductor from the main utility service panel to the AC/

DC Disconnect using an NEC compliant method.

5. Route the conductors through the tting and into the wire raceway

in the disconnect. Refer to Table 4-5 to determine the appropriate

conductors.

6. Connect the ground conductor to the terminal marked with the ground

symbol located on the left side of the AC circuit board inside the

disconnect.

7. Connect the L2 conductor to the terminal marked “L2” on the AC

circuit board inside the disconnect .

8. Connect the L1 conductor to the terminal marked “L1” on the AC

circuit board inside the disconnect.

9. Ensure all connections are wired correctly, properly torqued and there

are no loose strands of wire.
