DC Wiring
The dc wiring enters the DC Disconnect Box through the conduit located on the bottom of the disconnect
box. Use #6 AWG wire for the PV array connections.
PV Array
If a PV array is used in the system, connect the wiring as follows:
NOTE: For dual controller models, split the PV arrays output evenly between the two PV Array Disconnects.
1. Route the wires from the PV array through the conduit located at the bottom of the DC Disconnect Box.
2. Connect the positive (+) wire from the #1 array to the lower terminal of the PV Array #1 Disconnect
breaker.
3. Connect the positive (+) wire for the #2 array to the lower terminal of the PV Array #2 Disconnect.
4. Connect the negative () wires from the array(s) to the Grounding Block.
5. Connect the ground wire(s) from the frame of the PV array to the Grounding Block.
6. Ensure all connections are snug.
