3 Installation and commissioning
Danger
Installations and work may only be carried out with the device
deenergised (separated from the mains) and the motor shut down.
Death, cardiac arrhythmia
► Observe the 5 safety rules, see chapter List of safety and installation
notes on page 5
3.1 Positioning
3.1.1 Location
The motors should be installed/fitted while easily accessible and at an ambient or coolant temperature
+60°C. Altitude of site max. 1000 m (above sea level).
The cooling air should be able to flow in and out unhinderedly and should not be directly sucked in
again. The air inlets and outlets, as well as the channels between the cooling ribs, should be protected
against dust and dirt and regularly cleaned.
If the product is installed with the shaft end upwards or downwards, it should be guaranteed that no
water can penetrate the upper bearing.
3.2 Mountings for motors
Foot-mounting motors must be positioned and mounted on an even, vibration-free surface. All
mounting feet must lie flat; place thin sheets underneath for levelling if necessary.
For flange motors, care must be taken to ensure the axial run-out of the counterflange. Axial run-out
errors may result in bearing damage and/or the failure of sealing systems.
3.3 Condensation drain holes
Care must be taken to ensure that the available condensation drain holes are located at the lowest
point of the motor after installation and are kept free from dirt.
Closed condensation drain holes (if present) should be opened from time to time and closed again
before each start-up.
3.4 Balancing
Danger
Rotating parts
Severe injuries
► Secure feather keys against being ejected
The balancing type is indicated on the shaft end face of the motor shafts in accordance with DIN ISO
8821:
•
Balancing with a half key “H”
•
Balancing with a full key “F”
Observe the appropriate balancing type when installing the drive element!
3.5 Insulation resistance check
Before commissioning of the motor, or after a longer storage period or downtime (more than 6
months), the insulation resistance of the winding should be checked. Check the winding against mass
by means of an insulation resistance measuring device (max. DC voltage 500 V). If the minimum
