- Cut the wall / panel along the dotted line

with a jig saw.

- This will create a pocket in the wall / panel

for ush mounting of Charge Controller SCC-30AB.

2. Make sure the PV currents will not exceed the ratings of the SCC-30AB.

3. The connections to the SCC-30AB terminals are shown in the drawing at Fig. 5.2.

A barrier type of Terminal Strip has been provided for connecting the PV array and

the battery. M-4 screws with clamping washers are used to make the connection. A

at or a #2 Philips head screw driver may be used to tighten these screws. Tighten

each terminal clamping screw to 20 inch-pounds of torque. The distance between the

barriers is 9 mm and a standard Spade Type of terminal lug meant for # 8 Stud and

AWG #10 – AWG #12 wire may be used at the end of the wires to be connected to

these terminals. 4 such terminal lugs are provided with the unit for ease of installation

4. Set the DIP Switch 1 for the voltage system, set the DIP Switch 2, 3, 4 for battery

charging algorithm.

5. Connect the BATTERY rst. Be careful that bare wires do not touch the metal case

of the controller.

• The BATTERY must be connected before the Solar Panel (Module)/Array to

properly start the microcontroller, activate protections & guide installation.

• A battery below 9 volts may not start the microcontroller properly. Make sure the

battery is charged before installing the system.
