Measure the distance between top of
the panel and ceiling. Add sufficient
length above the ceiling to allow for
proper support and fastening. Cut the
pole to length. Slide power pole up to
ceiling and mark outline, and cut the
power pole opening in the ceiling tile.
With panels in final location, slip trim
plate onto power pole. Bend ears on
trim plate up and slide along length of
tube allowing plate to float (Figure A).
Insert power pole through ceiling tile.
Attach long leg of “L” brackets to
top of panel using 1/4" hex washer
head self tapping screws provided
(Figure A). Attach "L" brackets to
power pole using 10 x 24 x 5/8"
Phillips pan head screw provided.

an approved manner (Figure D).
Figure D
Mount electric box to a “caddy” tee bar
box hanger (caddy no. 512 or similar)
that has been clipped on the ceiling
suspension “tee” bars. The box should
then be positioned for vertical alignment with the panel.

Important:
The tee bar brackets and the box must
be securely attached to overhead
suspension wires so that the box load is
not supported by the ceiling (Figure D).
An adjustable bar hanger (RACO 926)
or similar can be attached to the upper
face of the box (Figure E) or a footed
support (RACO 429 or similar) can be
attached to the holes in the vertical
power pole (Figure F). Either option
should be rigidly connected to the
ceiling supports.

Attach trim plate ears to power pole
using 1/8" inch pop rivets.
Note:
Power supply to the junction box must
be 1/2" trade size or other approved
conduit.
After installation is completed the top
opening in the power pole may be
sealed with an approved sealant if
required by codes.
In Canada:
A CSA approved box must be supplied
by contractor and installed to Canadian
Code.

Warning:
Do not interconnect panels powered
from different feed units. This can
cause shock and fire hazard. This panel
system may be connected to more than
one source of supply. All sources must
be disconnected prior to any servicing.
No single circuit may be powered by
more than one source.
