GP-PWM-30 
________________________________________________________________________
4.  Wiring the GP-PWM-30. Wire the GP-PWM-30 according to the 
wiring schematic in Section 11. Run wires from the solar array 
and the batteries to the location of the GP-PWM-30. Keep the 
solar array covered with an opaque material until all wiring is 
completed. 
5.  Torque all terminal screws to 16 inch pounds (1.8N.m). 
Connect the battery wiring to the controller first and then connect 
the battery wiring to the battery. 
IMPORTANT: Always use appropriate circuit protection on any 
conductor attached to a battery. 
With battery power attached, the controller should power up and 
display information. Connect the solar wiring to the controller and 
remove the opaque material from the solar array. The negative 
solar array and battery wiring must be connected directly to the 
controller for proper operation. Do not connect the negative solar 
array or negative battery controller wiring to the chassis of the 
vehicle. 
6.  Mounting the GP-PWM-30. Mount the GP-PWM-30 to the wall 
using the included four mounting screws. 
IMPORTANT: You must set the battery type on the GP-PWM-30 
before you begin to use the controller. The default battery setting is 
for AGM batteries. 
Congratulations, your GP-PWM-30 should now be operational. If the 
battery power is low and the solar array is producing power, your battery 
should begin to charge. 
7.  Re-torque: After 30 days of operation, re-torque all terminal 
screws to ensure the wires are properly secured to the controller.
