instructions
Working on the electric motor:
Work must not be carried out on the electric motor until the motor had come to a
standstill and is de-energized. All connections, such as screw connections, that were
loosened must be tightened again prior to commissioning.
When carrying out work on the motor, please observe the technical instructions and
notes in the respective chapters in these Commissioning and Manitenance
Instructions.
Danger to life through electrical shock:
Make sure that the motor is disconnected and de-energized.
Never disconnect the motor connections while in operation.
Only connect measuring device when motor is disconnected from power supply and
de-energized.
Only commence work on the motor connections when you are sure that the motor is
de-energized and that there is no electric 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.
Dismantling the safety devices:
The electric motor must not be commissioned without first mounting the safety
devices.
When dismantling safety equipment during commissioning, ensure that the machine
is taken out of commission.
Remount the safety devices immediately after completing commissioning.
Danger on 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 drive shaft when it is de-energised and the motor has come to a
standstill. Otherwise, danger through rotating rotor.
Danger of burns! Never touch the motor housing when motor is running at rated load.
Surface temperatures can rise up to 70°C.
