NOTE: In North America, the pump and panel are pre-wired at the factory for 120V. If an alternate voltage
is to be used consult the factory.
Wiring from the power supply to the panel and pump must be 12 AWG or larger to maintain proper voltage
under full load conditions.
The circuitry for the panel and pump is suitable for a 20 AMP circuit maximum.
