MECHANICAL INSTALLATION
1) Assemble, on the operator, the securing corners and the anti-
vibration spacers as shown in Fig. 8.
2) Open the cover, unscrewing the securing screws.
3) Fit the operator on the plate, using the supplied washers
and nuts as shown in Fig. 9.
During this operation, route the cables through the raceway
on the operator's lower half-body (Fig. 10 ref. A).
Take great care in unsheathing all the cables so that the
cable gland grips only the individual wires (Fig.10 ref. B).
To access the unit, refer to chapter 5.
4) Adjust the height of the feet and the distance from the gate
- refer to Fig. 11.
5) Secure the gearmotor on the foundation plate, tightening
the nuts as shown in Fig.12.

INSTALLING THE RACK
4.4.1.
STEEL RACK TO BE WELDED (Fig.13)
1) Fit the three threaded pawls on the rack element, locating
them in the upper part of the slot. In this way, play on the slot
will accommodate any adjustments that may be necessary
later on.
2) Manually place the leaf in closed position.
3) Rest the first section of the rack level on the pinion gear, and
weld the threaded pawl on the gate as shown in Fig.14.
4) Move the gate by hand, checking whether the rack rests on
the pinion gear, and weld the second and third pawl.
5) Position another rack element next to the previous one, using
a section of rack as in Fig.15, to synchronize the teeth of the
two elements.
6) Move the gate by hand and weld the three threaded pawls,
carrying on until you have covered the entire gate.
6) Set the operator for manual operation as described in
chapter 8.
