• 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.

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
High electric voltage! Danger to life, risk of injury
by electric shock.
While the rotor is rotating, motors with perma-
nent magnet excitation create a voltage > 60 V at
the motor connections.
Any work may only be carried out while the motor
is at standstill.
Never connect or disconnect plug connectors
under load!
NOTICE
Never touch the connection points of electro-
static sensitive devices!
− Mounted components e.g. temperature
sensor, encoder) can contain parts suscep-
tible to electrical discharge (ESD).
Observe ESD safety measures.
