Attach Cable Management Option—Cable Fingers
The Cable Fingers (Part # 010200078) option permits routing cables in the void between Knurr DCM
racks in a cluster configuration. The cables can be strung through the fingers of the Cable Fingers
and into an adjacent rack.
A Knurr DCM will accommodate two sets of the Cable Fingers installed one above the other in a 42U
or 45U cabinet.
Hang the Cable Fingers on the rails by fitting the tabs into slots as shown in Figure 22. The
uppermost tab on the Cable Fingers should be in the fourth slot from the top.
Cable Fingers should be hung on each rack for easier routing of cables into each.

4.12.1 Install a Liebert MB Mounting Bracket
The Liebert MB mounting bracket is needed for installing a Liebert MB modular busway on a Knurr
DCM. The Liebert MB provides power connections to multiple rack-mounted and room power
distribution units, uninterruptible power systems and surge protection devices. The Knurr DCM
cabinets must be aligned, but need not be attached in a cluster configuration. Refer to the Liebert MB
user manual for details on installing the power supply system.
The mounting brackets attach at the rear of the Knurr DCM. One bracket must be installed in each
Knurr DCM to hold the Liebert MB securely (see Figure 23).
