Live wires.
Risk of electrical shock.

Electrical installation work must only be executed by qualified personnel.

Make sure that the power supply for the motor is compatible with the data on the nameplate of
the motor.

If the machine is equipped with a power connector, install a residual current protective device to

stallation.

Provide a lockable disconnect switch or an emergency stop switch on the power line so that the
machine is completely secured in case of an emergency situation.
