Installing a New Safety Switch
1. Open the conduit drill guides of the new Safety Switch (refer to
Opening Conduit
Drill Guides
on page 35).
2. Position the new Safety Switch below the inverter and from the inside of the inverter
grab the AC and DC wires extending from the switch conduits.
3. Attach the Safety Switch with its bracket to the wall and slightly close the screws. Do
not over tighten.
4. Securely screw the two conduit nuts onto the conduit ends in the inverter. Verify
proper conduit sealing.
Connecting the Safety Switch to the Inverter
1. If ferrite beads were removed from the DC and AC wires, place them on the wires
and close them. Make sure the DC labeled ferrite bead is placed on the DC wires and
the AC labeled ferrite bead is placed on the AC wires.
2. Connect the DC, as follows:
Connect the red wire to any of the DC+ terminals in the inverter.
Connect the black wire to any of the DC- terminals in the inverter.
