1. The EMC does not correctly operate on three-phase mains with the motor neutral connected to the neutral of the mains. If you have
2. The overload relay must be adapted to the motor.
3. Please take care not to make short circuits while installing the bypass contactor or the backward wires for delta wiring.
4. In case of devices planned to be used connected to a bypass contactor, the control voltage will have to be held sufficiently to allow the bypass
5. In case of fast softstarting and softstopping controls without waiting for the end of the ramps, the motor may heat up. Please contact your motor
