Motor cable insulation checksDisconnect the motor cable from terminals U, V and W of the AC drive and from the motor.Measure the insulation resistance of the motor cable between each phase conductor aswell as between each phase conductor and the protective ground conductor. The insula-tion resistance must be >1M at ambient temperature of 20°C.2. Mains cable insulation checksDisconnect the mains cable from terminals L1, L2 and L3 of the AC drive and from themains. Measure the insulation resistance of the mains cable between each phase conduc-tor as well as between each phase conductor and the protective ground conductor. Theinsulation resistance must be >1Mat ambient temperature of 20°C3. Motor insulation checksDisconnect the motor cable from the motor and open the bridging connections in themotor connection box. Measure the insulation resistance of each motor winding. Themeasurement voltage must equal at least the motor nominal voltage but not exceed 1000V. The insulation resistance must be >1M at ambient temperature of 20°C. Always followthe instructions of the motor manufacturer.
