WARNINGS / CAUTIONS
WARNING: 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.
WARNING: Install properly DC rated, high interrupt current limiting over-current protection and
disconnect equipment between the SC1 and the battery. Suitable fused disconnect switches
are low cost and provide protection from fire and damage due to over-current. Refer to the
National Electrical Code or your local alternative energy vendor for recommendations.
CAUTION: DO NOT subject the controller to voltages greater than the "Array Voltage, Max Voc"
as stated in the SC1 specifications. This is the open circuit voltage (Voc) of the solar panel, or
the sum of the open circuit voltages of all modules connected in series.
CAUTION: DO NOT exceed the maximum current rating ("Charge Current, Max") of 30 amps (or
50 amps with P-Option). This is the sum of the maximum power currents of all the modules in
parallel.
CAUTION: On higher voltage units (36, 48 volt), exercise extreme care during installation. These
voltages can be extremely dangerous in that they can create large arcs, which can burn or
cause other injuries.
