1. Check that the motor cable is connected to the motor and disconnected from the drive output
terminals U, V and W.
2. Measure the insulation resistance between each phase conductor and the Protective Earth
conductor using a measuring voltage of 500V DC. For the insulation resistance of other motors,
please consult the manufacturer’s instructions.
Note
: Moisture inside the motor casing will reduce the insulation resistance. If moisture is suspected,
dry the motor and repeat the measurement.
D.5 Fuse
It is necessary to add fuse for the avoidance of overload.
It is appropriate to use a breaker (MCCB) which complies with the VFD power in the 3-phase AC
power and input power and terminals (R,S,T). The capacity of the VFD should be 1.5-2 times of the
rated current.
Due to the inherent operating principle and construction of circuit breakers,
independent of the manufacturer, hot ionized gases may escape from the
breaker enclosure in case of a short-circuit. To ensure safe use, special
attention must be paid to the installation and placement of the breakers. Follow
the manufacturer’s instructions.
It is necessary to install the electromagnetic contactor in the input side to control the switching on and
off safety of the main circuit. It can switch off the input power supply during system fault.
