Connecting the Motor

DOK-ECODR3-DKC**.3-CS*-PR02-EN-P
Mounting the MSM motors:
Mount the motor. All of the measures and tolerances specified in the
dimensional sheets must be kept.
To fix the flange, we recommend to use the screws and tightening
torques listed in the table below.
Motor frame Recommended
size screw size
MSM020B 4x M3
MSM030B 4x M4
MSM030C 4x M4
MSM040B 4x M5
Fig. 15-1: Locking screws
Note: The screwed connections must be able to take up both the
force due to the force of the motor and the forces acting during
operation.
After having mounted the motor mechanically as specified, proceed to
connecting the motor.
Danger to life by electric voltage! Handling
within the range of live parts is extremely
dangerous. Therefore:
⇒ Any work required on the electric system may only be
DANGER
carried out by skilled electricians. It is absolutely
necessary to use electric tools.
Before starting work, the system must be de-
⇒
energized and the power switch be secured against
unintentional or unauthorized re-energization.
Before starting work, the appropriate measuring
⇒
equipment must be used to check whether parts of
the system are still applied to residual voltage (e.g.
caused by capacitors, etc.). If yes, wait until these
parts have discharged.
Injuries to persons or property are possible!
Interrupting or connecting live lines may cause
unpredictable dangerous situations or lead to
physical damage. Therefore:
WARNING
⇒ Connect and disconnect plug connectors only when
they are dry and de-energized.
During operation of the system, all plug connectors
⇒
must be securely tightened.
