• Tighten the screw connections for the electrical connections to the stipulated torque (see
Appendix 1 or technical documentation which accompanies the product)
• The type of protection is retained.
Note: All cable entries that are not required must be sealed with sealing elements. The sealing
elements must be fully functional and undamaged when the terminal box is closed.
4 Commissioning, operation
4.1 Safety instructions
Working on the electric motor:
Work must not be carried out on the electric motor until the motor has come to a
standstill and is electrically isolated. All connections, such as screw connections, that
were loosened when working on the motor must be tightened again prior to
commissioning.
When carrying out work on the motor, please observe the technical instructions and
notes in the respective sections in these Commissioning and Maintenance
Instructions.
Attention: If the optional holding brake is fitted, it must not be used to secure
anything while working on the motor (e. g. for retaining loads)!
Risk of fatality due to electric shock:
Make sure that the motor is disconnected and electrically isolated.
Never disconnect the motor connections during operation.
Only connect measuring instruments when the motor is disconnected from the power
supply and electrically isolated.
Only commence work on the motor connections when you are sure the motor is
electrically isolated and there is no potential.
When in operation, electric potential can be found at the motor terminals/contacts and
at the motor windings. Never touch these modules/elements while the motor is in
operation.
Installing and uninstalling safety devices:
The electric motor must not be commissioned without first mounting the safety
devices.
The motor must be put out of operation when installing and dismantling components
and systems which are provided for monitoring the motor for safe operation.
Danger on physical contact:
Make sure that the electric motor has come to a standstill and is secured against
accidental restarting before you touch it.
Only touch the output shaft when it is electrically isolated and the motor has come to
a standstill. Otherwise there is a risk due to the rotating rotor.
Danger of burns! Never touch the motor housing when the motor is running at rated
load. The surface temperatures on the motors may exceed 70 °C.
