Mounting Instructions
Caution
Installing the CM50 for the 700 and 3000 series projectors should be performed only
after you are thoroughly familiar with all of the following safety checks and installation
guidelines. To do otherwise increases the risk of hazards and injury to the user.
Warning
The ceiling should be capable of supporting a weight of at least 250 kg (441 lbs). If it
cannot, the ceiling must be reinforced. Improper installation may result in serious
personal injury.
Caution

6000-series (maximum dual stacked) projectors.
Use with other appliances may result in instability causing possible injury.
Maximum load: 70kg (154 lbs)

4.1 Determination of the mounting distance between SCREEN and FRONT CEILING SUPPORT
Configuration A
PD = perpendicular projector distance between screen and front side of the projector
(see installation manual of the projector).
Important:
For the Projectors 700 series: the perpendicular distance between the support and
the screen is the same value as the calculated PD.

Mounting the ceiling support:
Preparation:
- Place the support on the ceiling on the right
distance from the screen and perpendicular
to the screen.
- Mark at least 4 fixation holes on the ceiling
(minimum 2 on each side of the support and
as far as possible to the edges of the sup-
port).
- Remove the upper support and drill holes in
order to be able to insert bolts (M10) which
guarantee a downward support of at least
250 kg (441lbs).
