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. It is recommended that the requirements of the U.S. National Electrical Code
(NEC) or other applicable code should be followed.
WARNING: Follow all safety precautions of the battery manufacturer and the NEC.
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 over-current protection between
the SCS and the battery. Refer to the current NEC or other applicable code for
recommendations.
WARNING: 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.
WARNING: To remove all power from the controller, all three circuit breakers must be
turned off (including the load).
CAUTION: DO NOT subject the controller to voltages greater than the "Array Voltage,
Max. Voc" as stated in the SCS 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 50 or 90 amp current rating of the SCS. This is the
sum of the max. power currents of all modules in parallel.
