●
The servo drive is directly connected to an industrial power supply, with no
isolation such as a transformer. A fuse or circuit breaker therefore must be
connected to the input power supply to prevent electric shock in the servo system.
For the sake of safety, install a residual current device (RCD) to provide protections
against overload and short circuit or a specialized RCD to protect the grounding
cable.
●
Do not start or stop the motor by using the electromagnetic contactor. As a high‑
inductance device, the motor may generate high voltages instantaneously, which
may break down the contactor.
