Correct installation of cooling units
The cool air should be directed to the bottom of the drive. The natural convection will draw the air through the drives.
The cool air from the cooling unit should not be directed straight onto/into the drives. It should be allowed to mix with the
warmer air already in the cabinet, which can minimize the risk of condensation forming.
Cabinet top mounted cooling units require a method of directing the cool air from the cooling unit to the bottom of the drives.
In the case of a door mounted unit it may be necessary to direct the cool air with the use of a baffle.
Notes on the laying of cables in drag chains
The MOTION-CONNECT cables between the drive and the motor, and setpoint cables between the drive and the controller
satisfy requirements for use in drag chains.
Observe the following notes when laying these cables in drag chains:
Laying cables separately in the drag chain
To ensure a long service life of the drag chain and cable, lay cables made of different materials separately with
separating webs in the drag chain.
Fill the webs evenly to ensure that the position of cables does not change during operation.
Distribute cables as symmetrically as possible according to their weights and dimensions.
Use webs to separate cables with different outer diameters.
Keep cables untwisted in the drag chain.
