3.5 Wiring
Prior to connecting any wires to the controller, be sure you have a system wiring diagram to use as a reference
(see figure 2). Guessing at polarity and connection points is not worth the risk of potential product damage
and/or personal injury.
Ensure the wire sizes are of adequate diameter (gauge) to minimize voltage drop. Please refer to a DC voltage
loss table or call your SunPumps dealer for assistance. Wire gauge being too small will cause excessive voltage
losses to the motor and will reduce the flow rate of the pump.
All other system equipment should be installed before proceeding with wiring the controller. Double check
polarity and wire termination tightness before powering up the system.
CAUTION: Photovoltaic panels produce DC electricity when exposed to sunlight. Cover the panels with
a blanket or with a non-opaque material before wiring. Install a disconnect switch between the solar
modules and the controller.
