Enclosure
DANGER! Adhere to the “Important Safety Instructions” presented at the front of this document.
NOTE! Refer to Figure 4.4 and Figure 4.5 as this procedure is performed. A system installed in a relay rack is shown in the
illustrations. The procedure for a system installed in an enclosure is the same except as noted in the following procedure
steps.
Procedure
1. If the system is installed in an enclosure, refer to “Removing the Enclosure Rear Panels” on page 13 and remove the enclosure
rear panels.
2. Install the expansion module mounting assembly directly below the bottom-most module mounting assembly in the rack or
enclosure. Use the mounting hardware provided in the expansion busbar kit.
Hardware build-up is:
12-24 x 3/4" screw and flat washer, (1) set per side.
12-24 x 3/4" screw and ground washer, (1) set per side.
NOTE! Install the ground washers so the teeth make contact with the metal on the mounting angles. Torque all screws to 65
in-lbs.
3. On the rear of the expansion module mounting assembly, remove the rear shield that covers the output busbars. For a
system installed in a relay rack, on the bottom-most module mounting assembly in the rack, remove the rear shield that
covers the output busbars
NOTE! Apply electrical anti-oxidizing compound to busbar mating surfaces before performing the next step.
4. Secure the existing shelf’s busbars to the expansion shelf’s mating busbars with the supplied interconnect busbars and
hardware.
Hardware build-up for these connections are:
1/4-20 x 1" bolt,
1/4" Belleville lock washer,
1/4" flat washer.
Install the Belleville lock washer so the concave side is towards the busbar. Torque all connections to 60 in-lbs.
If installing a second expansion module mounting assembly, 1/4-20 nuts (included) are required in lieu of the 1/4-20 x 1”
bolts (see Figure 4.4).
5. Disconnect the cable coming from the distribution cabinet from the bottom connector on the bottom-most existing module
mounting assembly.
6. Connect the bottom connector on the bottom-most existing module mounting assembly to the top connector on the
expansion module mounting assembly.
7. Connect the cable disconnected in step 4 (coming from distribution cabinet) to the bottom connector on expansion module
mounting assembly.
