9.1Safety guidelines for commissioning

DANGER

Risk of death, serious personal injury, and/or material damage if a machine that does not fulfill the recognized safety requirements is commissioned.

Plants and machines with converter-fed low-voltage three-phase motors must fulfill the protection requirements of the EMC Directive 2004/108/EC. The plant engineer is responsible for ensuring that installation is carried out in an EMC-compliant manner. The signal and power cables must be shielded. Refer to the EMC installation guideline (order designation 6FC5297-□AD30-0AP□) issued by the converter manufacturer.

DANGER

Unexpected movements of the motor may result in a risk of death, serious personal, and/or material damage.

Danger from rotating rotor. Never carry out work in the vicinity of rotating parts when the machine is switched on.

Keep persons away from rotating parts and areas where there is a danger of crushing. Ensure that the rotors can rotate without hindrance.

Check the commutation setting before switching on the machine. Note also the commissioning instructions issued for the drive system.

Limit the motor currents.

Set low values for speed limiting. Monitor limit positions.
