Assembly Instructions
Assemble units as described herein only. To do otherwise
may result in instability. All screws, nuts and bolts must be
tightened securely and must be checked periodically after
assembly. Failure to assemble properly, or to secure parts
may result in assembly failure and personal injury.

Electrical Installation -
Overview
Important: Assembly of all
frame components must be
completed, with panel frames
secure to each other and leveled
prior to installation of electrical
components.
Before installing electrical
components, consult local
inspectors and authorities for
local codes. Connection to the
building power supply may be
made ONLY after all panel wiring
has been completed. Building
connections must be made by
a licensed electrician, following
local codes for the building site.
Note: Each circuit must be
individually protected with a
120-volt, 15 or 20-amp circuit
breaker device which will
provide disconnect and overload
protection.
Prior to beginning electrical
component installation, read
and understand the following
electrical installation section and
be familiar with the electrical
components and all power infeed
locations required.
Note: Data cable installation is
not covered in this document.
For data cable installation and
management, refer to the Unite
Planning Guide (KI-62226).
Note: The following steps show
10-wire rigid wireways installing
to frames before installation of
10-wire jumpers. However, some
installers find it more convenient
to install jumpers before securing
rigid wireways.
Base-Power 10-Wire Rigid
Wireway
Note: 10-wire rigid wireways
accept 10-wire power infeeds,
horizontal & vertical 10-wire
jumpers and 10-wire duplex
receptacles with simple modular
snap connection. Rigid wireways
must be installed with the “N”
symbol oriented up.
1. Position the 10-wire rigid wireway
under the lower horizontal frame
member (N symbol oriented
up) such that mounting tabs on
the rigid wireway fit up between
the two tangs of the wireway
mounting bracket. Align all four
mounting holes of the rigid
wireway with the four holes of the
wireway mounting brackets, and
secure using two #10-24 x 3/8”
Torx screw (31.12.9070) per
bracket, one from each side of
the rigid wireway. Use the left
mounting holes on one side
of the bracket, and the right
mounting holes on the other side
of the bracket so that mounting
screws do not interfere with each
other (Figure 1).
2. Repeat the process in step 1
above to install remaining
base-power 10-wire rigid
wireways to all panels that are
powered, or will have power
passing through them, per your
space-planning layout (Figure 1).
Note: If vertical 10-wire
jumpers are to be used between
base-power and beltway 10-wire
rigid wireways in any panel
frame, refer to page 21, Figure 2
as vertical 10-wire jumpers
should be installed before rigid
wireways.
Beltway-Height 10-Wire Rigid
Wireway
Note: 10-wire rigid wireways
accept 10-wire power infeeds,
horizontal & vertical 10-wire
jumpers and 10-wire duplex
receptacles with simple modular
snap connection. Rigid wireways
must be installed with the “N”
symbol oriented up.
1. At 30” beltway height, install
beltway-height supports into the
vertical frame member by tipping
the inside of each support up,
inserting the hook-tabs into the
vertical slots, and rotating the
support down into horizontal
position as illustrated. Repeat for
second required beltway-height
support across from the first
(Figure 1).
2. Install a wireway mounting
bracket to the mounting hole
of each beltway-height support
using 1/4-20 x 5/8” machine screw
(12.0074), as illustrated from
underneath each support. Make
sure bracket is aligned straight
onto support before tightening
(Figure 1).
3. Position a 10-wire rigid wireway
above the pair of beltway-height
wireway mounting brackets
(N symbol oriented up) such
that mounting tabs on the rigid
wireway fit in between the two
tangs of the wireway mounting
bracket. Align all four mounting
holes of the rigid wireway with
the four holes of the wireway
mounting brackets, and secure
using #10-24 x 3/8” Torx screw
(31.12.9070) screws per bracket,
one from each side of the 10-wire
rigid wireway. Use the left
mounting holes on one side of the
bracket, and the right mounting
holes on the other side of the
bracket so that mounting screws
do not interfere with each other
(Figure 1).
4. Repeat the process in steps
1 through 3 above to install
remaining beltway-height 10-wire
rigid wireways for all panels that
are powered, or will have power
passing through them at beltway
height, per your space planning
layout (Figure 1).
