Electric Actuator Wiring Precautions
Nov 17, 2018
1. The accessible bare conductor of the motor, electric heater and electric actuator must be grounded (PE) or connected to zero (PEN).
2. The insulation resistance of the motor, electric heater and electric actuator should be greater than 0.5M¦¸.
3. For motors above 100kW, the DC resistance values of each phase should be measured, and the mutual difference should not exceed 2% of the minimum value; the motor with no neutral point should be measured, and the DC resistance value between the lines should not exceed 1 of the minimum value. %.
