CEILING MOUNTING
- In order to mount the four metal brackets shown on Fig. “B” above on the upper aluminium frame of the
SI-H XL 300, please use screws, washers and crowned nuts mentioned on “C, D, E” of the supplied
equipment list; put inside the groove of the aluminium frame the crowned nut as shown on Fig. 1A;
connect the ceiling bracket to the profile by the socket head screws and the crowned nuts, move the
ceiling bracket along the profile in order to position it where needed (Fig. 1B); now tighten firmly the
screws of the four brackets.
- Note: the four ceiling mounting brackets can be mounted in two different ways on the upper frame of
the lift:
1- Brackets mounted towards outside – Fig. 8A – page 7
2- Brackets mounted towards inside – Fig. 8B – page 7
- Once the four brackets have been mounted on the upper frame of the lift, mount the lift to the ceiling
using wall plugs and screws (NOT supplied) specific for the type of material to drill. During the installation
pay attention that the lift is perfectly levelled both on the width and on the depth. (See Fig. 2).
ELECTRIC CONNECTION
- The motor has the possibility to be controlled via the supplied handheld RF remote control or via wired
low voltage contact closures.
- The motor has a six-core power cable. NEVER CONNECT THE MAINS TO THE WIRES WHITE, WHITE-
BLACK, WHITE-ORANGE.
- Once the lift is mounted to the ceiling, connect the wires brown, blue and yellow/green to the mains,
following the scheme shown in Fig. 3A;
- The lift is supplied with a safety mechanism (Fig. 3B) with a double security system: first - this is a
mechanic safety system that prevents the steel cable to unroll when the speed has reached 50 rpm;
second – this is an electrical security system that disconnect the electrical connection of the motor if the
force driven on the steel cable, caused by the falling down, is more than 503 Nm.

FIXING THE PROJECTOR TO LIFT
- Roll down the SI-H XL 300 by pushing ▼ button on the remote control (Fig. 7A), in order to lower the lift
till the lower end-stop (SERVICE mode), preset in the factory at 2,5 mt. ca. In case you wish to modify
the lower end-stop (SERVICE mode), please refer to instructions at page 4 and 5.
In order to fix the projector under the lift, position the splines of the three profiles of the lower lift frame,
to match the anchoring points on the projector (Fig. 4A).
Unloose the four screws as shown on Fig. 4B and position the three profiles where needed (Fig. 4C).
Once you have aligned the splines of the profiles with the anchoring points on the projector, tighten the
screws and the bolts of the profiles following a cross scheme.
Repeat this step until all the screws on the three profiles will be very well tightened.
Insert the screws for mounting the projector in the milling of the profiles (milling depth 10 mm) and
tighten the screws to the anchoring points of your projector.
ADJUSTMENT OF PITCHING AND ROLLING OF THE PROJECTOR
Projectors have not a regular distribution of the weight on their surface but tent to have unbalancing caused
by the lamp, by the optical system and so on.
Unbalancing could lead to either a right and left rolling or a pitching of the lower lift frame - projector.
The SI-H XL 300 have been developed to solve these problems and allow to adjust the lift in order to get a
perfect balance of the entire lifting system.
In order to adjust PITCHING, please move the motor along the profile where the motor itself is fixed, by
loosing the screws as shown on Fig. 5A and 5B and move the motor left or right until the lower frame will be
perfectly balanced (Fig. 5C).
PLEASE, PROCEED WITH THIS STEP, AFTER HAVING LAYED THE PROJECTOR MOUNTED ON THE
FRAME ON A SUPPORT SURFACE, IN ORDER TO LIGHTEN THE MOTOR FROM THE WEIGHT.
Now loose the screws on Fig. 5D and using a rubber hammer, move the profile of Fig. 5E, left or right in
order that the steel cables are perpendicular both to the upper part and to the lower part of the lift (see Fig.
5F). At the end of the adjustment, tighten the screws firmly (Fig. 5D).
