1) Drill mounting holes in reference to "Mounting hole dimensions" ( 11 page).

 Drill two penetration holes in the ceiling beam for the ceiling mount bolts.

 Drill two holes in the ceiling board for passing the ceiling mount bolts (M10) through and one hole in the

ceiling board for pulling the indoor wiring through.

2) Attach the two ceiling mount bolts.

 Securely ﬁ x the two ceiling mount bolts to the ceiling beam.

 If the place for ﬁ xing the ceiling mount bolts is not strong enough, sufﬁ ciently reinforce it giving

consideration to safety factors.

3) Pull out the indoor wiring for the power supply from the ceiling.

 Pull out the indoor wiring for the power supply from the indoor wiring hole you drilled in the ceiling board.

4) Attach the ceiling mount bracket to the ceiling mount bolts.

 Pass the indoor wiring for the power supply through the indoor wiring hole of the ceiling mount bracket and

then securely ﬁ x the ceiling mount bracket to the ceiling mount bolts.

 The ends of ceiling mount bolts at the ceiling mount bracket side should protrude by approx. 5 mm (3/16")

from the hexagonal nuts.

 Make sure the distance from the surface of the ceiling mount bracket to the end of the ceiling mount 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.

 Be sure to use commercially available ﬂ at washers and spring washers to install the ceiling mount bracket.

Attention

 Tighten the hexagonal nuts ﬁ xing the ceiling board and ceiling mount bracket 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 speciﬁ ed torque. Also take a measure such as using two nuts or

thread-locking ﬂ uid to prevent loosening of the hexagonal nuts.
