Installing the adjustable rails
EMC Rails and Enclosures (CX3-10 Class and CX3-20 Class Storage Systems) Field Installation Guide
1. Locate and unpack the rail kit that accompanied your enclosure.
The front edge of each rail is stamped L or R for left and right
sides, when they face the cabinet front.
Note: The predrilled holes in the cabinet channels are based on the
NEMA-standard U measurement. The holes are predrilled at distances of
1/2 inch, 5/8 inch, 5/8 inch (totaling one U), then 1/2 inch, 5/8 inch, 5/8
inch (another U), and so on. On EMC 40U and 40U-C cabinets, horizontal
lines or small holes in the channel mark the 1U increments.
Refer to Figure 13 on page 22
2. From the front of the cabinet, insert the right rail alignment pins
above and below the bottom U mark on the rear NEMA channel.
3. Pull the adjustable rail forward to the inner side of the front
channel (the surface facing the rear of the cabinet), and align the
four holes on the rail with those in the channel.
4. Secure the rail to the front channel using two of the provided
screws at the middle two holes of the rail. Leave the screws slightly
loose to allow for adjustment after you install the enclosure.
5. Repeat Steps 2 through
6. From the rear of the cabinet, use two of the provided screws to
secure each rail to the rear channel. Tighten the screws.
