Connecting the DC ground

Installing the HI400

7.Insert the other end of the negative (–) cable into the negative (–) terminal on the HI400 and tighten the terminal screw. Ensure all strands of wire are inside the connector (no stray strands). The terminal manufacturer’s recommended tightening torque is 21 inch-pounds.

8.Attach the positive (+) cable to the breaker or fuse and disconnect combination installed on the battery positive

(+) terminal in step 5. Tighten the connection according to the manufacturer’s recommendations.

9.Insert the other end of the positive (+) cable into the positive (+) terminal on the HI400 and tighten the terminal screw. Ensure all strands of wire are inside the connector (no stray strands). The terminal manufacturer’s recommended tightening torque is 21 inch-pounds.

10.Verify the polarity of the DC connections is correct: positive (+) on the inverter connected to the positive (+) on the battery, and negative (–) connected to the negative (–).

When you are ready to operate the inverter, close the DC circuit breaker or disconnect switch to supply DC power to the inverter.

The chassis ground lug on the DC end of the inverter is used to connect the chassis of the inverter to your system’s DC grounding point as required by installation codes for some installations.

Use copper wire that is either bare or provided with green insulation. Do not use the DC ground lug for your AC output grounding wire (see the AC wiring instructions on page 12 in this section).

To connect the DC ground:

➢Connect a No. 8 AWG copper wire between the HI400’s chassis ground lug and the DC grounding point for your system.
