Mounting steps
Note
Mounting steps for air-cooled motors
The mounting steps 1, 13, 14, 15, and 16 are only required for air-cooled motors.
1. Disassemble the fan and intermediate housing from the the motor.
2. Removing the sealing cover
3. If necessary, perform complete balancing of the motor with external balancing disks
4. Screw the rotating part of the rotating union into the NDE motor shaft extension and tighten
with the appropriate torque (against the wrench grip surface on the NDE motor shaft
extension).
5. Mount the adapter for the static part (not included in the scope of delivery) on the encoder
cover with 6x M5 screws. Position the adapter in such a way that the leakage connection is
at the lowest point (with horizontal mounting).
6. Mount the hoses for leakage and sealing air on the adapter, if necessary using angled
elements
7. Mount the hose for the supply to the static part of the rotating union, if necessary using
angled elements
8. Screw the static part onto the adapter
9. Always connect the hoses for leakage sloping downward (min. 15°).
10.Also connect the hose for the inlet sloping downward.
11.Manually check that the rotor turns easily.
12.Perform a hydrostatic test for leaks
13.Make a cutout for the inlet and leakage hoses in the intermediate housing.
14.Push the intermediate housing with the inlet over the hoses and screw it to the motor. Protect
the hoses from mechanical loads
15.Screw the fan on to the intermediate housing
16.Seal the remaining openings between the cutout and the hoses
4.6.3 Mounting information and instructions
• Do not mount any additional anti-rotation pins on rotor-supported rotating unions
• Never screw pipes directly to the rotating union.
• Always use a hose between the rotating union and the xed piping. To do this, route the
hoses in curves and torsion-free.
