Technical data
‘‘O’’ Series electrical systems
Equity
To assist the specifier/electrician in
specifying ‘‘O’’ Series the following
technical information is available.*
Power Supply
Electrical Infeed
Two different types of infeeds are
provided which are specially
designed to connect to the two
general categories of building
distribution: ceiling distribution in
raceways ending in junction boxes
and floor duct or wall outlets.
Base Infeed Module: Modular
base-mounted infeed conduits are
provided for connection to building
power supplies housed in underfloor
outlet boxes, floor mounted or wall
outlet boxes. Available ‘‘unhanded’’
for ease in introducing power from
left or right of infeed location. The
cover plates of floor monuments,
recessed floor boxes or wall boxes
are to be punched to receive a
half-inch (trade size) knockout hole
for installation of the box fitting,
which is included on the infeed
circuit. The wiring connection is to
be made within the box inside the
monument or behind the floor or wall
flush plate. The 4 1 /2 conduit can be
shortened to meet field conditions by
cutting the infeed (loose) end. Base
Infeed Module plugs into terminal
block.
Ceiling Infeed Module: The straight
tubular infeed may be shortened (on
its bottom end) if it will not telescope
sufficiently into the module to fit
field conditions. Ceiling Infeed
Module is filled with 8- wire conduit
and plugs into terminal block in
adjacent panel.
Raceway Panels with
field-installed componentry:
1. An independent cableway with
capacity for up to ten 3 /8 dia.
communications cables.
2. ‘‘Multiple Branch Circuit’’ power
wiring consisting of eight wire
providing four separate 20-amp
circuits, plus an isolated ground.
3. A terminal block at the center of
the panel baseboard for
panel-to-panel electrical connection
and placement of duplex receptacles.
4. Two locations, one on each side of
the center of the panel (back to
back), into which duplex 15-amp
receptacles can be placed. The
raceway covers are provided with
removable knockouts.
For increased electric demands a
second duplex receptacle per panel
side can be added to panels 36 and
wider. The Side Mount Receptacle
(SMR3) plugs directly into the left
side terminal block connector ends
and always accesses circuit #3.
5. End-to-end and face-to-face
symmetry for ease in ordering,
erecting and installation of power
and communications cabling. The
faceplates on both sides of the panel
are removable without removing
receptacles.
The system and all standard
components are UL-listed.
*Because of our continuous product
improvements, these specifications
are subject to change without
notice. Please consult a Knoll Sales
Representative for
the latest information prior to
ordering.
