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 SC3/20 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 reverse battery "PLUS" and "MINUS" connections to the SC3/20.
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 SC3/20 at the same time. This will cause damage to the SC3/20 when the battery
reaches full charge voltage.
CAUTION: DO NOT wire the SC3/20 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.
