Electrical Disconnect power at service panel before connecting motor. Single phase motors come factory wired for 230 volt operation. Do not alter wiring in single phase motors. Match motor voltage to power supply voltage. Do not connect three phase motors to single phase power supply or single phase motors to three phase power supply. - Page 7 Electrical Before using pump, check your motor nameplate for voltage. Your electric supply voltage and the stamped nameplate voltage must agree. Motors stamped 200 volts only or 230 volts only, must be used with that voltage only. Motors stamped with two voltages (for example 230/460 volts), may be used with either supply voltage.
