1-7 Installation Steps:
This section provides a brief overview of how to get started using the SC Lighting Control Series
controller. However, please review the entire manual to ensure best performance and years of
trouble-free service.
NOTES:
●
The SC Lighting Control Series prevents reverse current leakage at night, so a blocking diode
is not required in the system.
●
The connector terminals will accept a maximum wire size of AWG #10 (up to 5.2
mm2). A flathead screwdriver is required. (Some #10 spade connectors may not fit in
this terminal.)
●
Tighten each terminal clamping screw to 20 inch-pounds of torque.
●
The SC Lighting Control Series is designed to regulate power from a PV array. Other
generators can be connected directly to the battery, however, with no effect on the
SC Lighting Control Series.
STEPS:
1. Mount the SC Lighting Control Series on to a vertical surface. Allow a minimum of 5 cm (2 inches)
space above and below the controller for air flow.
2. Make sure the PV and load currents will not exceed the ratings of the SC Lighting Control Series model
being installed.
3. The connections to the SC Lighting Control Series terminals are shown in the panel drawing.

4. Connect the BATTERY first. Be careful that bare wires do not touch the metal case of
the controller.
The BATTERY must be connected before the SOLAR to properly start the
microcontroller.
If the battery voltage is below LVD (low voltage disconnect) which can be selected by
MANUAL EQU/LVR and LIGHT TEST buttons, the load has been automatically
disconnected due to a very low battery charge condition, and the battery must be
recharged.
A battery below 10 volts may not start the microcontroller properly. Make sure the
battery is charged before installing the system.
5. Connect the SOLAR (PV array) next. The green LED indicator will light if the array is
