•
Avoid damaging the receptacle fit on the
plant side.
•
Use screws and washers for flange fas-
tening⮫ Chapter 6.2.2 "Mechanical inter-
faces" on page 31.
8.2 Assemble transmission
elements
NOTICE
Motor damage due to strikes onto the motor shaft
Do not strike the shaft end and do not exceed the
allowed axial and radial forces of the motor.
Fit and pull off the transmission elements such
as pulleys and couplings only with suitable equip-
ment; heat them, if necessary.
•
Avoid inadmissible belt tensions. Please con-
sider the allowed radial and axial forces in the
project planning manuals.
•
The balancing state of transmission elements
must comply with the full-key balancing of
the motors.

•
Use the centering hole for fitting transmis-
sion elements. For details on centering holes,
please refer to the specifications.
•
Heat the transmission element, if necessary.

Electrical connection

8.3.1 Electrical connection general
notes
WARNING
Danger! Electric voltage! Operations in the
vicinity of live parts are extremely dangerous.
−
Work required on the electric system may
only be carried out by skilled electricians.
Tools for electricians (VDE tools) are abso-
lutely necessary.
−
Isolate (even auxiliary circuits).
−
Secure against reactivation.
−
Ensure de-energization.
−
Ground and short-circuit.
−
Cover or shield any adjacent live parts.
WARNING
Risk of explosion due to improper handling
during motor connection!
Make sure that the motor is only connected in de-
energized state and a non-explosive atmosphere.
Before working on the system, always use a suit-
able measuring device (e.g. multimeter) to check
whether any parts of the system are still under
residual voltage (e.g. caused by residual energies
of capacitors in filters and drive units etc.) their
discharge times are to be waited for.
The connection between the protective con-
ductor terminal and the operating ground must
be made before any other connections.
The connection or terminal points to or on the
control unit must be located outside the poten-
tially explosive atmosphere or must be approved
for use in potentially explosive atmospheres.
