WARNINGS / CAUTIONS
WARNINGS: Electricity, even low voltage electricity, can be dangerous. Installation should be
performed by a licensed electrical contractor or other qualified personnel only. The
requirements of the U.S. National Electrical Code should be followed.
WARNING: Follow all safety precautions of the battery manufacturer. Proper ventilation must be
provided for vented batteries. Most vented batteries produce hydrogen gas when charging,
which is extremely explosive. DO NOT expose the battery to open flame, matches,
cigarettes or sparks.
CAUTION: DO NOT exceed the maximum current rating (Current, Short Circuit, Continuous) of
10 amps. This is the sum of the short circuit currents of all the modules in parallel.
CAUTION: DO NOT subject the controller to voltages (Array Voltage, Max Voc), greater than 26
volts. This is the open circuit voltage (Voc) of the array, or the sum of the open circuit
voltages of all modules connected in series.
CAUTION: DO NOT reverse battery "PLUS" and "MINUS" connections to the SC3/10. Reverse
polarity or accidental contact to the battery in reverse polarity will cause the fuse to blow,
and may damage the unit.
CAUTION: DO NOT connect the array directly to the battery when the array is connected to the
SC3/10 at the same time. This will cause damage to the SC3/10 when the battery reaches
full charge voltage.
CAUTION: DO NOT wire the SC3/10 in such a way that it can be connected to an alternator (or
other charging source) while the battery is disconnected, even if momentarily.
INSTALLATION INSTRUCTIONS
1. LOCATION: - The SC3/10 should be mounted where it can be easily seen and reached to
take the best advantage of the status lights. Carefully consider how the wires are to be run
from the solar panel to the controller, and from the to the battery. The SC3/10 should be
mounted as close to the battery as possible, and should be mounted on a vertical surface to
aid in cooling.
2. PROTECTION: - The unit should be mounted indoors, out of the weather, unless a
weatherproof enclosure is used. Avoid mounting in direct sunlight or in a hot environment.
Basically, do not mount anywhere you would not put a TV or stereo.
3. MOUNTING OPTIONS: - The SC3/10 is designed to be recessed into the side of a cabinet or
wall where the wiring can be accessed from the back. Allow 2 - 3 inches behind the unit.
The SC3/10 can also be mounted onto a standard, double gang electrical switch box
available at any hardware or electrical supply store. Install the switch box as for standard
electrical wiring, run the wires into the box and after connection of the SC3/10, fasten it to
the box as you would an electrical switch.
4. COMPLETE THE INSTALLATION OF PANEL, BATTERIES AND LOAD: - Follow the
manufacturer's instructions for mounting and wiring the solar panel, batteries and the load.
