WARNINGS
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.
CAUTIONS:
CAUTION: DO NOT EXCEED THE ASC’S VOLTAGE AND CURRENT RATINGS:
• Do not exceed the maximum voltage rating of the ASC (see SPECIFICATIONS).
Compare the ASC’s rating of the open circuit voltage (Voc) to the array, or the sum
of the Voc of all modules in series.
• Do not exceed the maximum current rating of the ASC (see SPECIFICATIONS).
Compare the ASC’s rating of the short circuit currents (Isc) to the array, or the
sum of all the modules in parallel. Remember that cold temperatures increase
the charging current from the modules. Refer to the temperature chart with the
module specifications.
CAUTION: DO NOT DEVIATE FROM THE RECOMMENDED WIRING INSTRUCTIONS:
• Do not reverse Battery(+) and Battery(-) connections to the ASC. Any reverse polarity
from the battery can damage the unit.
• Do not reverse the Battery and Array connections to the ASC. A battery connected to
the array terminals can damage the unit.
• Do not connect the array directly to the battery when the array is connected to the
ASC at the same time. This will damage the ASC when the battery voltage reaches
the Charge Termination set-point.
• Do not wire the ASC in such a way that it can be connected to an alternator (or other
charging source) while the battery is disconnected. Other charging sources should
have independent connections to the battery.
• Do not wire the ASC in such a way that it can be connected to a load without a
battery connected. (Example: Do not connect the loads directly to the ASC BATT
terminals. This will damage the ASC if the battery is disconnected.)
CAUTION: DO NOT OVER-TIGHTEN SCREWS:
• Do not exceed 8 inch pounds of torque on the terminal block screws during
installation. The screws are corrosion resistant nickel plated brass, and are softer
than standard steel screws.
