WIRING
Caution!
The battery must be wired to the charge controller before the solar panel is connected to
the charge controller.
A pair of 20 foot pre-assembled cables with Multi-Contact (MC) male and female connectors is provided
primarily to connect the solar panel to the charge controller. After making sure that sufficient length is
available to wire the solar panel to the charge controller, any excess wire maybe used to wire the battery to
the charge controller.
7.1. Battery to Charge Controller
• Mark the cables to differentiate between Positive and Negative.
• Make sure the Positive terminal (marked ‘+’) of the battery is connected to the Positive terminal (marked
“BAT +”) of the charge controller and the negative terminal (marked ‘-’) of the battery is connected to
the Negative terminal (marked “BAT -”) of the Charge Controller SCC-30AB (Fig. 7.1.1). If you are not
sure use a DC voltmeter to determine the polarity of the battery bank. Reverse polarity connection will
damage the Charge Controller and the resulting damage will not be covered by warranty.
• Crimp the insulated fork terminals provided (Fig. 7.1.3) to one end of the Positive and Negative battery
leads.
• Insert the fork terminals (Fig. 7.1.3) into the appropriate terminal on the charge controller: Positive
lead is connected to the Positive terminal (marked “BAT+”) of the charge controller Negative lead is
connected to the Negative terminal (marked “BAT -”) of the Charge Controller SCC-30AB (Fig. 7.1.1).
• Crimp the battery ring terminals (Fig. 7.1.2) provided to the Positive and Negative wire leads to be
connected to the battery terminals.
• Clean the battery post terminals free of corrosion and other impurities.
• Bolt the ring terminals to the battery terminals making sure the correct polarity is observed.
