Step 6
Secure the mounting chassis to the ceiling
board with the ceiling board fixing screws (4
positions, screws with label q).
Engage the top of the mounting chassis
q
with the anchor bolt (for securing the
mounting chassis).
Secure the mounting chassis by turning the
w
ceiling board fixing screws clockwise when
viewing it from beneath. Turning the ceiling
board fixing screws clockwise provides ceil-
ing board tightening between the bottom of
the mounting chassis and ceiling board fix-
ing bracket resulting in mounting chassis
securing.
Recommended tightening torque:
0.78 N·m {0.58 lbf·ft}
Important:
•
When securing the mounting chassis on
the ceiling, make sure that the 4 ceiling
board fixing brackets are open as shown in
the figure e.
Secure the top of the mounting chassis
e
with double nuts.

Step 7
Prepare the cables.
Run the cables from the space of the mounting
chassis. The wiring image with the bracket
mounted on the ceiling is described below. Be
careful to prevent the cables from being caught
on the ceiling board fixing bracket or others.
