Three-phase synchronous motor, water-cooled
English
In case of connection using a terminal box it is to be ensured
•
the insulation is not over stripped, i. e. that the insulation extends right up to the cable lugs or
terminals. The ends of the cables must not protrude.
•
the cable lugs that are used are suitable for the dimensions and cross-sections of the
terminals and cables.
•
the screwed electrical connections are tightened in accordance with the specified tightening
torque (comp.
Appendix 1 table 5
).
•
the protection type is maintained.
Note
: All lead-ins that are not used must be closed off with the sealing caps. The sealing
elements must be fully functional and undamaged when closing the terminal box.

Safety 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 sections in these Commissioning and Manitenance
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)!
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.
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 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
.
