DANGER
Dangerous shock currents
Earthing and shielding measures are required to protect devices and persons. To
ensure the safety of the operator earthing must be carried out with low impedance.
With respect to the ground connection one of the following actions must be done:
▶ connect the motor housing to the ground of the machine or
▶ connect the ground terminal of the motor connector to the central ground point
of the machine.
Consider the following with regard to shielding: Always use shielded motor cables!
