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.
6) Set the operator for manual operation as described in chapter
8.

INSTALLING THE RACK
4.4.1.
STEEL RACK TO BE WELDED (Fig. 13)
1) Fit the three threaded pawls on the
rack element, positioning them on
the upper part of the slot. In this way
the play on the slot will enable any
adjustments long-term.
2) Manually move the leaf to its closed
position.
3) Lay the first piece of rack level on the
pinion and weld the threaded pawl on the gate as shown
in Fig. 14.
4) Manually move the gate, checking if the rack is resting on the
pinion and weld the second and third pawls.
5) Fit another rack element next to the previous one, using a
piece of rack, as shown in Fig. 15, to synchronise the teeth of
the two elements.
6) Move the gate manually and weld the three threaded
pawls. Carry on like this until you have fully covered the gate.
