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 the batteries. Most batteries produce hydrogen
gas when charging, which is extremely explosive. Provide adequate battery
ventilation. 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 SC3/15 and the battery.
Suitable fused disconnect switches are low cost and provide protection from fire
and damage due to over-current. Refer to the current National Electrical Code or
your local alternative energy vendor for recommendations.
CAUTION: DO NOT exceed the maximum array open circuit voltage (Voc) of 26 volts.
This is the sum of the Voc of all modules in series.
CAUTION: DO NOT exceed the maximum current rating of the SC3/15 of 15 amps. This
is the sum of the short circuit currents (Isc) of all the modules in parallel.
CAUTION: DO NOT reverse battery "PLUS" and "MINUS" connections to the
SC3/15. 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 SC3/15 at the same time. This will cause damage to the SC3/15
when the battery reaches full charge voltage.
CAUTION: DO NOT wire the SC3/15 in such a way that it can be connected to an
alternator (or other charging source) while the battery is disconnected, even if
momentarily. Other charging sources should have independent connections to the
battery.
