This guide is for use by qualified personnel only.

Connecting the Unit

The following procedure is illustrated in Figure 2-9 on page 2–13.

To connect the charge controller in a negative-grounded system:

1. Make sure the PV array disconnect and battery disconnect are turned off.

2. Install a cable clamp into each knockout being used.

3. Ground the charge controller: connect a grounding conductor between a

charge controller ground lug and the grounding electrode (as shown in

Figure 2-9 on page 2–13).

4. Connect the PV array’s negative (–) output to the charge controller terminal

marked

PV –.

5. Connect the PV array’s positive (+) output to the PV array disconnect.

6. Route another positive (+) cable from the other end of the PV array

disconnect to the charge controller terminal marked

PV +.

7. Connect the negative (–) battery cable to the charge controller terminal

marked

BAT –.

8. Connect a positive (+) cable from the charge controller terminal marked

BAT + to the battery disconnect.

9. Connect a second positive (+) cable to the other side of the battery

disconnect and connect to the positive (+) battery terminal.

10. Torque the charge controller’s battery terminals to 25 lbf.in (2.8 Nm) and the

PV terminals to 15 lbf.in (1.7 Nm). Allow some slack on the cables within the

charge controller and secure the wiring with strain reliefs or cable clamps.

DANGER

HAZARD OF ELECTRIC SHOCK

Whenever a PV array is exposed to light, a shock hazard exists at the output

wires or exposed terminals. Open the array disconnect switch before making

the connections.

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

CAUTION

REVERSE POLARITY DAMAGE

Before energizing the charge controller from either the PV array or from the

battery, check the polarity of all power connections. Positive (+) must be

connected to positive (+). Negative (–) must be connected to negative (–).

Failure to follow these instructions can result in equipment damage.
