Motor Voltage Ratings
Motors with a withstand voltage rating from phase to earth of 1000V AC should be used. An
insulation withstand rating of 500V AC is acceptable if an isolating transformer with earthed
screen is used to power the system, and X1 pin9 (0V/GND) input is earthed, as specified.
Motor Safety Earth/Ground Connection
It is recommended that the motor is independently bonded to a local safety earth point. The
safety earth lead should be at least 2.5mm
