Installation To Concrete Ceilings - NEC NP600CM Installation And Assembly Manual

Installation to Concrete Ceilings

• Concrete must be 2000 psi density minimum. Lighter density concrete may not hold concrete anchor.
• Make sure that the supporting surface will safely support the combined load of the equipment and all attached hard-
ware and components.
Place projector mount assembly (A) on ceiling as a
3
template and mark the center of the two mounting
holes. Drill two 1/4" (6 mm) dia. holes to a minimum
depth of 2.5" (64 mm). Attach projector mount assembly
(A) using two Alligator
washers (E), and two #14 x 2.5" wood screws (F) as
shown in fi gure 3.1.
NOTE: Mounting slots on projector mount assembly
allow for 30° (±15°) of swivel adjustment before fully
securing wood screws.
Tighten wood screws (F) using 3/8" (10 mm) socket
wrench or phillips screwdriver until projector mount
assembly (A) is fi rmly attached.
WARNING
• Tighten wood screws fi rmly, but do not overtighten.
Overtightening can damage the screws, greatly reducing
their holding power.
• Never tighten in excess of 80 in • lb (9 N.M.).
WARNING
• Always attach concrete anchors directly to load-bearing
concrete.
• Never attach concrete anchors to concrete covered with
plaster, drywall, or other fi nishing material. If mounting
to concrete surfaces covered with a fi nishing surface is
unavoidable (not evaluated by UL), the fi nishing surface
must be counterbored as shown below. Be sure concrete
anchors do not pull away from concrete when tightening
screws. If plaster/drywall is thicker than 5/8", custom fas-
teners must be supplied by installer (not evaluated by UL).
