6) Remove the rear upper cover panel from each PDSC. This cover panel will be
re-installed after all mounting and electrical connection procedures have been
completed.. To do so: Loosen the screws securing the cover panel. Lift the
cover panel until the screw heads clear the keyhole slots. Remove the cover
panel.
7) Remove the plug-button located on the left side (towards the front) of each
PDSC, except the end PDSC. This opening is provided for data communications
cable routing between bays.
1) Place bay(s) and PDSC(s) in position. Note that PDSCs are placed to the left (as
viewed from the front) of each bay. Note that clearance holes for 1/4” bolts are
provided in the side rails of each bay and PDSC. These holes are for bolting the
bays and PDSCs together.
Placing and Securing the Bay(s) and PDSCs
2) Level bay(s) and PDSC(s) as required, using leveling feet in base plate. Adjust
leveling feet so that all bays and PDSCs are even at top, and bolt holes in the
side of each bay and PDSC line up with holes in the adjacent cabinet(s).
3) Bolt all bays and PDSCs together. Use 1/4” hardware, five places per pair of
cabinets. Use a ground washer in two locations with the 1/4" hardware bolting
two cabinets together.
Note: A ground washer is an internal-external tooth, dish-type lock washer.
When installing ground washers, ensure that the ground washer is
oriented so that the teeth dig into the paint on the metal part the ground
washer is secured to (concave side faces the metal part).
4) Install shims between bottom of each bay and the floor as required to distribute
floor loading.
5) Secure Power/Distribution Bay(s) and PDSC(s) to floor using fastening hardware
per site requirements.

install them now (two per side). Note that ground washers are used with each
screw securing the side cover panels.
