Protrudes 20 mm (25/32") to 30 mm (1-3/16")*
the ceiling surface.
*1 27 mm (1-1/16") to 30 mm (1-3/16") for double nuts
1) Drill mounting holes in reference to "Mounting hole dimensions" ( page 12).
z Drill anchor nut or curled plug mounting holes to match the size specified by the manufacturer.
z Drill two through holes in the ceiling board for the hanging bolts (M10).
2) Attach the two hanging bolts to the concrete ceiling.
z Attach the anchor nuts or curled plugs to the concrete ceiling and securely fix the two hanging bolts.
z When installing anchor nuts or curled plugs, strictly adhere to the installation instructions supplied by the
manufacturer so that they will not come out or loosen, or be dislodged from the intended positions.
z If the ceiling concrete has become weak and fragile or may have degraded as a result of aging, reinforce it
with iron or wood.
3) Use hanging bolts to mount the attachment plate.
z The ends of hanging bolts at the attachment plate side should protrude by approx. 5 mm (3/16") from the
hexagonal nuts.
z Make sure the distance from the surface of the attachment plate to the end of the hanging bolts is within 30
mm (1-3/16"). If the distance is too long, the projector mount bracket will not be able to be attached.
z Be sure to use commercially available flat washers and spring washers to install the attachment plate.
Attention
z Tighten the hexagonal nuts fixing the ceiling board and attachment plate together while considering the strength
of the ceiling board material. If the ceiling board material is of low strength, the ceiling board may be damaged
if the nuts are tightened to the specified torque. In this case, also take measures such as applying double nuts
or screw lock to prevent loosening of the hexagonal nuts.
Note
z When mounting the attachment plate to the hanging bolts, there is no need to install the falling prevention wire
to the ceiling.
