Safety Instructions: Rack Mount

Elevated Operating Ambient: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.

Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuit might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

Reliable Earthing: Reliable earthing of rack-mounting equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

Disconnect Device (Pluggable Equipment): The socket-outlet shall be installed near the equipment and shall be easily accessible.

SETTING MACRO DISPLAY HEIGHT ON YOUR UPRIGHT PAIR (CONTINUED)

• There are 4 macro display height intervals labeled A, B, C, and D, along the inner post of each upright. (FIGURE B)

• Each macro display height interval is spaced 6" (152 mm) apart.

• Start determining which macro display height interval (A, B, C, or D) you should use in order to properly accommodate your display(s) by carefully considering measurements described on the next page.

A Inner Posts B C D Outer Sleeves FIGURE B

• Refer to the information provided with your display(s) to get an accurate display height measurement as shown. (FIGURE C)
• Take your accurate display height measurement along with your C3 height (either 32" (813 mm) or 24" (610 mm)) and make sure your selected macro display height interval provides adequate display clearance after reviewing the specific 6" (152 mm) upright pair height range on the table provided.

NOTE:

• A 4-Bay C3 credenza with a display mount option (C3-XX-LDXU) configured for dual displays (displays not included) shown.
• Although not installed yet in the overall procedure, the woodkit is shown on the frame for an accurate credenza height, display clearance, and provide a general idea of the look your display mount provides.

Slide until desired macro height letter shows through square opening on the outer sleeve (same letter on each upright) and secure with screw. FIGURE D

Macro Display Label	Height Range of Upright Pair
A	51" (1295 mm) to 57" (1447 mm)
B	57" (1447 mm) to 63" (1600 mm)

1. Slide the inner post through the outer sleeve on one of the uprights until your desired macro height letter shows through the square opening (the same letter for each upright) on the outer sleeve as shown. (FIGURE D)
2. Use electric drill, 38 " socket, and a 14 "-20 x 38 " hex head thread forming screw (B) to secure each upright to your selected macro height letter.

ATTACHING UPRIGHT PAIR TO THE FRAME AND YOUR WALL

NOTE:

• Each upright is attached to specific frame locations based on single or dual display installation.
- All models support single display installation.
- Only 3- and 4-Bay models support dual display installation.

1. Use the following figure to determine where to attach each upright to your frame for single or dual display installation. (FIGURE E)

1. Insert the studs on the bottom (inner post) on both of the macro height secured uprights into the holes on the top of the frame and place them against your wall.
2. Use level to ensure the uprights are vertically aligned on your wall before proceeding to step 4 and marking the wall inside the top slots of the 4 upper keyholes on the uprights.

ATTACHING UPRIGHT PAIR TO THE FRAME AND YOUR WALL (CONTINUED)

1. Use a pencil and mark your wall inside the top slots of the 4 upper keyholes on the uprights (A) as shown. (FIGURE F)
2. Remove the uprights from your frame and wall.

NOTE: Adjust torque on electric drill to the "drill" setting.

1. Use electric drill and 12 " drill bit to drill holes in the marked locations on your wall.

Pure electrical circuit lines without any symbols

Mark inside the top slots of the 4 upper keyholes for drill locations.

1. Insert SNAPTOGGLE® anchors (C) into holes by holding metal channels flat alongside plastic straps and sliding channels through holes.

NOTE:

• Refer to "Attaching Your Frame Using the Default (Frame Feet) Installation Height" on page 6 in the C3 Series Credenza Frame instruction sheet (100-00032) to revisit instructions on how properly use SNAPTOGGLE anchors in your type of wall.
• If you are not securing uprights using the provided SNAPTOGGLE anchors (preferred), and instead are going into wood studs or a solid concrete wall, you must provide your own lag bolt\ hardware.

1. Use electric drill 38 " socket and (2x) 10-32 flange nuts (D) to attach the upright to the frame.
2. Repeat the previous steps to attach the other upright.
3. Use electric drill, Phillips bit, 14 "-20 x 212 " bolts (E), and 14 " washers (F) to secure uprights to your wall. Do not overtighten.

NOTE:

• If you are not securing uprights using the provided SNAPTOGGLE anchors (preferred), and instead are going into wood studs or a solid concrete wall, you must provide your own lag bolt hardware.
• For more information, refer to “Attaching Your Frame Using the Default (Frame Feet) Installation Height” on page 6 in the C3 Series Credenza Frame instruction sheet (100-00032).

1. Slide the interlock tabs on the upright pair horizontal mounts (positioned with the set screws on the bottom) into the two channels on the back of the horizontal extrusion (G) as shown. (FIGURE H)
   NOTE: Verify the torque on your power driver is on the lightest setting and only increase as necessary.
2. Use electric drill, #2 Phillips bit, extrusion end caps (H) and (4x)14 "-20 x 12 " end cap screws (J) to attach an end cap on each side of the horizontal extrusion.

NOTE:

• There are 7 micro display height intervals labeled 1, 2, 3, 4, 5, 6, and 7 on the top of the pre-assembled lower portion of your upright pair.
• Each micro display height interval is spaced 1" (25 mm) apart.
• While carefully lifting the extrusion and placing the horizontal mounts over the upright pair, use the notch openings on the bottom of the mounts to select your micro display height interval (the same number for each horizontal mount) and secure each one with a single wire snap pin (K) through the holes right above. (FIGURE J)

NOTE: Horizontal extrusion (G) removed for clarity.

Secure micro display height setting with single wire snap pins (K) through horizontal bracket holes and uprights.

Slide horizontal brackets along sleeves until desired micro height number shows through notch openings (same number for both uprights).

1. Center the horizontal extrusion with your credenza and then use a #2 Phillips screwdriver to tighten the screw on the bottom of each horizontal mount to fix it in place.
2. Carefully attach the covers (R) to the front of your uprights.

FOR DUAL DISPLAY CONFIGURATIONS ONLY: If you purchased a C3 Series Display Mount Large Cover Option (C3-XX-XCVR-BK) for your dual display configuration, refer to the instruction sheet (100-00035) and use the option instead.

ATTACHING DISPLAY(S) TO THE HORIZONTAL EXTRUSION

NOTE: This topic must be done as the final part of your C3 installation process. Meaning, if you have not yet installed any other C3 Series options you may have purchased for your credenza, your woodkit, fan kit (if purchased), and large cover option (if purchased), you must first complete those steps (in that order) before returning to this topic and attaching your display(s) (display(s) not included) to the horizontal extrusion.

1. Use 12 " wrench, 5/16"-18 x 12 " studs (L), and flange nuts (M) to attach interface standoff brackets (N)

P N M N P L FIGURE K

1. Select from the appropriate size and length pan head screws from the interface hardware (IH-A) through (IH-M) for use with your display.

NOTE:

• Make sure the selected pan head screw length does not bottom out in the mounting hole on your display, or damage may occur. (FIGURE L)
• If you feel any resistance, stop immediately and try either a shorter screw or use spacers (IH-N) to take up slack.
• Verify the torque on your electric drill is on the lightest setting and only increase as necessary.
