Warning!
• This unit will be damaged if the battery is connected in reverse polarity.
• ENSURE that the battery + and - wires are correctly connected before proceeding.
• Damage due to reverse battery connection is not covered under warranty!
• When connecting the battery, connect the battery Negative first & then the battery Positive.
• When disconnecting the battery, disconnect battery Positive first & then battery Negative.

Installation Steps

This section provides a brief overview of how to get started using the SCC-30AB
controller. However, please review the entire manual to ensure best performance
and years of trouble-free service.
Notes:
• The SCC-30AB prevents reverse current leakage at night through an internal MOSFET Switch,
so an external Blocking Diode is not required in the system.
• The connector terminals will accept a maximum wire size of AWG #10 (up to 5.2 mm
• Tighten each terminal clamping screw to 20 inch-pounds of torque.
• The SCC-30AB is designed to regulate power from a PV array. Other chargers can be
connected directly to the battery, however, with no effect on the SCC-30AB.
Steps
1. As explained earlier in Chapter 4, SCC-30AB is designed for flush mounting on
a wall panel. It has a face plate and a projecting part at the back consisting of the
PCB with the Terminal Strip, connector for the Battery Temperature Sensor (BTS) and
the DIP switches. The wall / panel will be required to be cut to accommodate the
projections of the circuit board mounted on the back of the faceplate. All the wiring –
2 wires from the Solar Array, 2 wires to the battery and 2 wires to the optional Battery
Temperature Sensor (if used) will be led to the connections at the back of the unit
from behind the wall / panel. Make sure that the pocket created behind the cut-out
in the wall / panel is clear so that the back portion carrying the PCB is not damaged
when the unit is pushed back into the cut-out section of the wall / the panel for flush
mounting.
The front face plate of the SCC-30AB acts as the heat sink for the heat dissipating
components mounted on the PCB at the back of the Front Panel face plate. Hence, please
ensure that the Front Panel face plate is not located near a heat generating source and that
there is adequate cooling air flow across the face plate to remove the heat dissipated from
its surface.
