OMPONENTS

A Knurr DCM may have any or all of the components addressed in this section, depending on its configuration.

2.1

Frame

The base of all Knurr DCM products is the frame. The Knurr DCM features a fully assembled, extruded aluminum frame with a patented T-slot that permits many of the cabinet’s tool-less mounting features.

The racks can accommodate shelf- or rack-mounted equipment on 19-inch (483mm) adjustable rails.

See Knurr DCM model numbers on page 28 and illustrations for measurements of different models.

Cutouts in the top covers permit customer cable entry. The top of the Knurr DCM also is drilled for mounting a Liebert XDV top-mount cooling unit.

2.2

Enclosure

Exterior components of the Knurr DCM are painted black (RAL 7021)

2.2.1

Doors

All doors are framed from sheet metal and have hexagonal perforations leaving 83 percent of the door open to airflow for efficient cooling. A two-point latch and push button lock come standard.

Doors are available in single- or dual-door designs for easier access. All doors are removable and single doors are designed for reversible (left/right) hinging (see 3.7.1 - Remove the Door and 3.7.2 -

Reverse the Door). Each type of door swings 135 degrees. Each door is perforated; each is available in RAL 7021, matching the rack

Doors are available in these styles and sizes:

• 1200mm x 600mm, single, Part # 538444G1L

• 1200mm x 600mm, split, Part # 539273G1L

• 1200mm x 700mm, single, Part # 538444G2L

• 1200mm x 700mm, split, Part # 539273G2L















2.2.2

Side Panels

Side panels for each size cabinet are fashioned from sheet metal. Quarter-turn fasteners outside the unit permit removal of all panels for maintenance while preserving internal security during normal operation.

An optional side panel lock with keys (Part # 011399067L) is available to secure the side panel. The lock insert is installed near the bottom center of the side panel.

Installation

3.3

Unloading the Knurr DCM

Before unloading a Knurr DCM, note the weight of the model (see 6.0 - Specifications. Use at least two people when moving the unit.

1.

Using a pallet jack or forklift, move the Knurr DCM on its pallet to the installation location.

2.

Cut the shrink wrap and remove all packaging.

3.

Remove the lag bolts securing each shipping bracket to the shipping pallet; there is one bracket at each corner of the Knurr DCM; each bracket has two lag bolts (see Figure 3).

4.

Raise the leveling feet so that the rack will rest on the feet: a.

Use the supplied hex wrench to lower each caster until the Knurr DCM is not resting on the shipping brackets.

b.

Remove the hex bolts securing the shipping brackets to the Knurr DCM.

Leave the shipping brackets attached if they will be used to secure the cabinet to the floor.

5.

Use a pallet jack or forklift to raise the Knurr DCM off the shipping pallet.

6.

Slide the shipping pallet out from under the rack.

The Knurr DCM may be positioned for installation either with the forklift, by two or more people carrying it or by rolling the cabinet on its casters.

If the casters are to be used to move the cabinet, the leveling feet must be raised by reversing Step 4 above. Position the cabinet and either lower the leveling feet or bolt the cabinet to the floor with the shipping brackets.

3.4

Equipment Layout

To keep the unit’s center of gravity as low as possible, install equipment from the bottom up, starting with the heavier units. Leave any unused space at the top of the enclosure.

!

CAUTION

After equipment is installed, the Knurr DCM may have a high center of gravity. Avoid tipping the unit when it is being moved.

Installation

3.5

Basic Hardware Installation—Nutbars and Spring Nuts

The Knurr DCM is designed with T-slots on exposed faces of the aluminum frame members. These

T-slots permit placing nutbars and spring nuts anywhere along a frame member to mount equipment at any distance desired (see Figure 4). Nutbars and spring nuts accept M5 and M6 screws used to attach most equipment and options to the rack’s aluminum frame members.

Inserting a Nutbar or Spring Nut

To insert a nutbar or spring nut into a T-slot on the Knurr DCM frame, compress the spring on the back of the nutbar and slip it into the T-slot (see Figure 5). If the nutbar or spring nut does not flatten out into the slot, press down on the edge of the block that is too high.

Properly installed nutbars and spring nuts have the thread hole section on the outer side of the T-slot

(see Figure 5). The leaf spring holds the nutbar or spring nut in place while a screw is threaded and tightened. Nutbars and spring nuts can be pressed down with a small tool and moved for better alignment.

Front- and Rear-Mount Rails—Position and Attach

Front- and rear-mount vertical rails are installed in the Knurr DCM at the factory at 29.13inches

(740mm). They are secured to the 600mm Knurr DCM’s aluminum frame using threaded block nutbars in the T-slot at top and bottom of the EIA rail and M6 x 12 screws. Mechanical fasteners in are used in center of the EIA rail to tie into the center depth support member. Vertical rails are installed in the 700 and 800mm Knurr DCM using a cross-brace at the top; node brackets are used at the bottom and on the center horizontal rails. The cross-brace and node brackets attach to the cabinet frame with Torx head screws and nutbar. The rails can be moved to change the front-to-rear distance between the rails.

NOTE

The front and rear vertical rails must be kept at a 90-degree angle to the upper and lower aluminum frame members. The left and right front vertical rails must be the same distance from the front of the rack; the left and right rear vertical rails must be the same distance from the rear of the rack.

If those conditions are not met, equipment and optional features will be difficult to install.

Cluster Configuration

Two or more Knurr DCM cabinets of the same height can be connected in a cluster with the optional

Cluster Kit of suite brackets and flexible dress strip (24U, Part # 539608G1; 42U, Part # 539608G2;

45U, Part # 539608G3) or with the standard, factory-installed cluster tab. The brackets put the cabinets on 24" (609.6mm) centers, which matches the size of U.S. floor tiles, enhancing integration with underfloor cooling systems. The bracket and plastic strip serve as finishing pieces and close the gap between the cabinets.

Connecting Knurr DCMs is easier if the units have been moved to their final installation position before beginning to attach them in a cluster.

4.8.1

Connect Two Racks Using the Tool-Less Cluster Kit

1.

Remove the adjacent side panels from the cabinets that will be clustered together (see 3.8.1 -

Remove a Panel). The panels on the outside of the cluster can be left on the cabinets to help manage airflow.

2.

Get the needed number of tool-less rack cluster kits.

One kit will cluster two racks together in front and rear. Two cluster kits will cluster three cabinets togethers, three cluster kits will cluster four cabinets together and etc. Each cluster kit contains four interchangeable metal cluster brackets and two plastic filler strips. Pressing the filler strips into the opening between the cabinets reduces the loss of cold air.

3.

Level the cabinets and make sure both frames are the same height off the floor.

4.

Remove the racks’ doors (see 3.7.1 - Remove the Door if necessary).

5.

Install a cluster bracket as shown in Figure 17 by pressing the integral pins into holes in the cabinet frame.

The brackets can be installed in any order, starting with either the top of the cabinet or the bottom of the cabinet.

6.

Secure the cluster bracket in place with two quarter-turn fasteners as shown in Figure 17.

7.

Repeat Steps 5 and 6 for the remaining cluster bracket.

8.

Snap the plastic strip in the gap between the cabinets.

4.8.2

Connect Two Racks Using the Factory-Installed Cluster Tab

Cabinets being clustered using the cluster tab can be clustered with or without the side panels. To do so:

1.

Make sure the cabinets are the same height off the floor.

2.

Remove the bolt on the top of adjacent corners of the racks, front and rear, as shown in the top left illustration in Figure 17.

Swing cluster tab over to adjacent cabinet and reinsert and tighten the bolt.

Figure 17 Cluster connections

Remove the bolt shown above on the left cabinet. Swing the cluster tab over to the cabinet on the left and reinsert and tighten the bolt. Repeat for rear of cabinet.

Position the cluster bracket against the front of the cabinets to be connected. Insert and tighten two low-profile quarter-turn fasteners.

Snap the dress strip into place to complete the cluster connections.

4.9

Cable Management

When designing the equipment layout in the Knurr DCM, consider how cables must be run for each configuration and how cable runs affect cooling, access and operational factors, such as separating power and communication cables to reduce electromagnetic interference.

Good cable management contributes to:

• Effective airflow for cooling

• Easier cable identification

• Improved access

• Reduced electromagnetic interference

• Proper bend radii, particularly for fiber optic cables

• Adequate support for large cables and heavy cable bundles

NOTE

When installing cables, leave enough slack for the unit to be rolled forward or sideways for access to components.

Do not defeat the ground/earth connections between the utility/mains outlet and the Knurr

DCM.

Once equipment has been installed, cables for power and communication may be connected. Before making any connections, check the equipment to ensure that all power switches are in the Off position.

Numerous cable entrances and management provisions are built into the various Knurr DCM configurations to ease cable installation.

Additionally, these cable management options are available to assist with routing power and control cables to reduce electromagnetic interference and to improve airflow:

• Cable Fingers—Part # 010200078

• Lobster Claw pack of 10, Part # 002185050 pack of 100, Part # 002185070

• Velcro Straps pack of 10, Part # 002185060 pack of 100, Part # 002185080

• Cable Trough, (482.6mm), Part # 050400558

• 1U Cable Routing Panel—Part # 011170208

• 1U Cable Routing Panel with D Rings—Part # 011171448

Velcro straps are field-attached in any number of ways. They can be wrapped through slots in the internal mounting rails and support vertical cable management, attached through small brackets or to other components.

21


4.10

Cable Access—Top Cover, Back and Base

A fully removable top cover is available on Knurr DCM enclosures. These features are available:

Top Cover Cable Management Kit

Top Cover Cable Management kits assist in organizing cables routed across the top of one or more

Knurr DCM racks. Panels may be attached to the front, rear and sides of the Knurr DCM and a center management unit may be installed in the center of the racks.

The front, rear an side panels attach to the cabinet with the bolts at each corner (see Figure 19).

Center cable management units attach to the Knurr DCM with tabs that fit into slots on the top cover. They are held in place by spring tension.

1.

Install the center piece first by squeezing it and sliding the four tabs into the holes in the top of the rack.

2.

Remove the frame-member bolts at the front left and front right corners of a Knurr DCM.

3.

Position the front top cover cable management panel so the holes at each end align with the bolt holes.

4.

Reinsert the bolts and tighten them.

5.

Repeat Steps 2 through 4 for the rear of rack.

4.11.1 Internal Cable Management Troughs

Internal Cable Management Troughs may be installed to support wiring across short spans, such as when it must cross the width of the cabinet. The optional accessory mounts on the Knurr DCM’s 19" rails as shown in Figure 20. Use spring nuts, washers and screws to mount trough to rails or to the aluminum frame members.

Figure 20 Internal cable trough installation mechanical fasteners

4.11.2 1U Cable Routing Panel

Cable Routing Panels (Part # 011171448) may be installed to separate cables and wiring to reduce clutter, to reduce chafing and to ease determining a cable’s purpose, such as communication to a server. The optional accessory mounts on the Knurr DCM’s rails, as shown in Figure 21. Insert cagenuts in rails where the radial limit will be installed, attach the routing panel and pull cables through the slot.

Routing panels may be installed to separate cables and wiring to reduce clutter and improve airflow.

The optional accessory mounts on the Knurr DCM’s rails, much like the cable routing panel. Insert cagenuts in rails where the routing panel will be installed, attach the routing panel and slip cables through the prongs.

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).

Figure 23 Liebert MB mounting brackets

Quarter-turn fastener in one side of the bracket permits opening and closing to install the

Liebert MB

Liebert MB fits in either or both of these adjustable slots in this double busway bracket

Liebert MB installed with single busway bracket; mounting brackets must be installed in alternating slots

To install Liebert MB mounting brackets on a row of Knurr DCM cabinets:

1.

Insert the bottom of the mounting bracket through one of the two slots in the rear of the first

Knurr DCM in the row.

2.

Hold the bracket against the cabinet frame member and attach it with metal quarter-turn fasteners (see Figure 24)
