Three-phase synchronous motor
English
•
In the interest of ensuring operational safety, we recommend that you use connecting cables
assembled by Baumüller (see Technical Product List).
•
Before connection, the plugs, sockets and the terminal boxes must be checked for damage,
corrosion, dirt and dampness.
•
Ensure the connections are made correctly and are tight. Seals and sealing faces on the connectors
and
the
terminal
boxes
maintain
the
type
of
protection.
Note!
Also in the interests of safeguarding the degree of protection, the rotatable junction boxes
should not be turned in their direction of connection more than 5 times altogether.
•
Connectors and terminal box connections must not be exposed to mechanical stress. If necessary,
protect against strain, shearing, twisting and kinking.
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.
Section
8.2 table 4
/
8.3 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 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.
