Installing the Truecharge 2 Battery Charger

Step 2: Connecting the DC Chassis Ground (Earth)

ELECTRICAL SHOCK HAZARD

Improper connection can result in risk of electric shock. See note below.

Failure to follow these instructions can result in death or serious injury.

NOTE: Have an electrician install a properly grounded circuit if one is not available.

The Truecharge2 Battery Charger must be connected to a grounded, metal, permanent wiring system, or an equipment-grounding conductor should be run with the circuit conductors and connected to the equipment-grounding lead on the charger. Connections to the battery charger must comply with all local and application-specific codes and ordinances.

Xantrex recommends that you install a DC chassis ground (earth) wire from the ground stud on the Truecharge2 Battery Charger to the engine bus or DC ground bus. The DC chassis ground (earth) wire should be sized correctly with the power conductors, and both must be sized for the battery fuses that are used to protect the DC wiring. Refer to your local electrical codes to verify the requirements in your jurisdiction for your application.

To connect the DC chassis ground (earth):

1.Locate the ground stud on the Truecharge2 Battery Charger.

2.Connect the DC chassis ground (earth) from the ground stud to the ground bus. See Figure 4, “Configuration for Normal Loads” on page 8.

Use a flat washer, a lock washer and a nut (included in the installation kit) to secure the connection.

3.Tighten the nuts to 2.3 N-m (20 lb-in.) torque and test that the wire is secure. Do not over-tighten as this may result in damage to the charger.
