5 - Anchoring the gear motor

After identifying the position where you are going to install the gear motor (which can be to the right or left of the gate), you can anchor the gear motor
to the ground in two ways:
A) by bedding the base plate into a concrete plinth (to be constructed)
B) by anchoring the plate to a concrete plinth (pre-existing or to be constructed) using 4 high-strength M10 metal anchor bolts (not supplied)
Note: the plate must be bedded in concrete or anchored taking care to respect the measurements given in Fig. 3 to ensure that the pinion meshes
correctly with the rack.
We recommend that the plate is always bedded into a plinth that has a height of a few centimetres above ground level to avoid the risk of water collecting
around the gear motor.
A) Bedding the plate in concrete
1) Screw the M8x50 screws (ref. A) fully into the threaded inserts (ref. B) in the plate (Fig. 4A).
2) Fit the rubber plugs (ref. A) on to the screws M8x50 (ref. B) screwed into the plate (Fig. 4B). These plug are essential as they prevent the cement
adhering to the screws, so that, if necessary, the screws may be removed in the future.
3) Using a screwdriver, lift up the anchor tabs (Fig. 4C).
4) Position the plate so that the arrow (ref. A) is pointing towards the rack (Fig. 4D).
5) Insert the corrugated pipes for cables in the square hole (ref. B); the hole can accept one 32 mm pipe and one 25 mm pipe. If additional corrugated
pipes are to be installed, open up the second square hole (ref. C) in the plate (Fig. 4D). The corrugated pipes must project 5 cm beyond the plate.
6) Cast the concrete, making sure that the plate is positioned perfectly level.

B) Anchoring the plate with expansion bolts
If there is no pre-existing plinth, construct a perfectly level and sturdy concrete plinth with an area sufficiently larger than the plate.
1) If a plinth is to be constructed, cast the concrete making sure that the corrugated pipes are positioned so as to allow the plate to be subsequently
positioned correctly relative to the gate, as indicated in Fig. 3.
2) Turn the plate over through 180°, keeping the arrow pointing towards the rack (Fig. 5A), and position it in accordance with the measurements in Fig.
3 and use it as a template to mark out the positions of the 4 holes for the anchor bolts (ref. A) and the gear motor fixing screws (ref. B) (Fig 5B). The
plate must be turned over otherwise the threaded inserts would prevent it from lying flat.
3) Mark the centres of the anchors and of the screws and drill holes for the high-strength M10x120 anchor bolts (not supplied) and the holes for the gear
motor fixing screws (at least Ø14 with min. depth 60 mm).
4) Reposition the plate and secure it to the concrete plinth.

6 - Operator height adjustment and fixing

The operator has a height adjustment mechanism to facilitate the adjustment of the clearance between the rack and pinion and to compensate any
lowering of the track without having to adjust the rack.
To adjust the height and fix the gear motor, proceed as follows:
- If the M8x50 gear motor fixing screws are still screwed into the plate, unscrew them.
The gear motor base is fitted with 4 captive nuts positioned on the underside of the gear motor casting, alongside the fixing slots. Screw the 4 studs
provided into the nuts through the holes (ref. A Fig. 6A).
- Position the gear motor observing the measurements shown in Fig. 3. Rest the gear motor on the plate in its working position, fit the washers to the
M8x50 fixing screws (ref. A Fig. 6B) and screw them in by just a few turns without tightening.
- Screw in the studs to position the gear motor at the correct height and to ensure the correct clearance between the pinion and the rack; use a spirit
level to check that the gear motor is level.
- Once the gear motor is positioned correctly, tighten the fixing screws.
