SAVE THESE INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INSTRUCTIONS FOR MODEL GP-PWM-10-FM and GP-PWM-30-SB THAT SHOULD BE
FOLLOWED DURING INSTALLATION AND MAINTENANCE OF EITHER CONTROLLER.
Disconnect all power
sources
Electricity can be very dangerous. Installation should be performed only by a licensed
electrician or qualied personnel..
Battery and wiring safety Observe all safety precautions of the battery manufacturer when handling or working
around batteries. When charging, batteries produce hydrogen gas, which is highly
explosive. Ensure batteries are in a well-ventilated space, away from sparks for open
ames.
Wiring connections Ensure all connections are tight and secure. Loose connections may generate
sparks and heat. Be sure to check all connections one week after installation to
ensure they are still tight.
Work safely Wear protective eyewear and appropriate clothing during installation. Use extreme
caution when working with electricity and when handling and working around batteries.
Observe correct polarity Reverse polarity of the battery terminals and array will cause the controller to give a
warning tone. The controller will not function unless battery terminals are connected to
a battery with proper polarity. Failure to correct this fault could damage the controller.
Do not exceed the GP-
PWM-10-FM Amp current
and max voltage ratings
The maximum current of the solar system is the sum of parallel-connected PV mod-
ule–rated short circuit Currents (Isc) multiplied by 1.25. The resulting system current is
not to exceed 12.5A. If your solar system exceeds this value, contact your dealer for a
suitable controller alternative.
Do not exceed the GP-
PWM-10-FM max voltage
ratings
The maximum voltage of the array is the sum of the PV module–rated open-circuit volt-
age of the series connected modules multiplied by 1.25 (or by a value from NEC 690.7
provided in Table 690.7 A). The resulting voltage is not to exceed 35V. If your solar
system exceeds this value, contact your dealer for a suitable controller alternative.
