Application Notes
Power infeeds connect building
power supply to a cluster of
interconnected power rails. Desk
support infeed snaps into the end of
any desk power rail, and includes 6
foot liquid-tight conduit and pigtail
for connection to floor or wall
electrical box. Panel/desk connector
transmits power between the end of
a desk support rail and any panel
base power rail outlet position.
Hardwire infeed, used in all New
York City installations, includes
junction box that mounts to the
inside of a desk support corner leg.
Electrical contractor supplies
conduit from building power supply
to box and trims power connector to
length. Hardwire kit includes
painted finish cover panel.
Duplex outlets are preconfigured to
access one of the six circuits, A, B,
C, X, Y, Z, and snap into any
standard outlet location. Duplexes
on circuits X, Y, Z may be specified
with orange face or black face with
orange triangle to signify protected
circuits for electronic equipment; all
other duplexes are black.
Grommet outlet module stands in
any Morrison (not Options)
worksurface grommet for convenient
access. Grommet outlet module
accepts only special duplexes
(MR1-DA or MR1-DB) on circuits A
or B.
Contact protectors enclose open
conductors on power rail wherever
outlets or power connectors are not
planned.
Cable sleeves contain and protect
power and data cables passing
between desk supports.
