Installing a Parallel Configuration

A parallel configuration is when two Truecharge2 Battery Chargers are coupled together to increase the output capacity. For example, a 40-amp Truecharge2 Battery Charger can be connected with another 40-amp Truecharge2 Battery Charger for a combined 80-amp capacity charger. This configuration is possible only with the use of the optional remote panel.

DAMAGE TO THE BATTERY CHARGER

Do not parallel Truecharge2 Battery Chargers together without a Truecharge2 Remote Panel (part number: 808-8040-01).

Failure to follow these instructions can damage the unit and/or damage other equipment.

Installing a parallel configuration:

1.Follow the installation sequence (from steps 1 through 4) for a single unit - “Installing the Truecharge 2 Battery Charger” on page 16.

2.In “Step 4: Installing AC Wiring” on page 21, make sure that the two AC input lines come from the same circuit branch, that is, both AC input lines should have a common circuit breaker.

3.Designate a primary charger and a secondary charger between the two chargers. Remember that only the primary charger or remote panel can be used to configure and operate the parallel system.

4.Connect the primary charger’s battery bank 1 to the secondary charger’s battery bank 1. Do the same for battery banks 2 and 3. NOTE: A maximum of three battery banks can be connected to a parallel-configured charger system.

Parallel configuration can only be done when the following conditions are met:

Two Truecharge2 Battery Chargers must have the same output voltage rating. Never parallel a 24-volt charger with a 12-volt charger.

Both Truecharge2 Battery Chargers must connect to a Truecharge2 Remote Panel.

Both Truecharge2 Battery Chargers must be correctly installed.

5.Leave any unused DC output/s unconnected.

6.Connect the remote panel’s communications cable to the primary charger’s remote port and to the remote panel’s primary port. Do the same for the secondary charger.

7.Connect the BTS (or battery temperature sensor’s) cable plug to the primary charger’s BTS port. Then connect the BTS’s sensor to the battery.

NOTE: If you have two BTSs, you may connect the two separate cable plugs to each of the battery chargers’ BTS ports. You may then connect each of the sensors to two separate batteries. However, during operation, the BTS that is detecting a higher temperature will be used for battery temperature compensation.
