INSTALLATION

3.1 - Preliminary checks for installation

Warning! - The installation of the motor must be carried out by qualified
personnel, in compliance with current legislation, standards, regula-
tions and these instructions.
Before starting the installation, make the following checks:
• Check the integrity of the product components as soon as they are taken out
of the package.
• Check the suitability of the motor selected by comparing its nominal technical
characteristics with the technical characteristics of your rolling door; therefore,
DO NOT install the motor if its characteristics (nominal torque, rotation
speed and operation time) are not suitable to drive your rolling door. In
particular, the motor torque MUST NOT EXCEED the one required to
move the rolling door. Additional limitations on use are contained in the sec-
tion "Technical characteristics".
• In cases of outdoor installation, make sure the motor is adequately protected
against atmospheric agents.
• Check that the rolling door is well balanced: i.e. it must not move if left sta-
tionary in any position.
• Check that the rolling door does not have points of increased friction, during
both the closing and opening movement.
• Check that the rolling door follows a route with a regular and silent movement
during its travel.
• Check that the installation area is compatible with the size of the motor fig. 1.
• On the power line to the system, install a device for disconnection from the
power mains with a gap between contacts that assures complete disconnec-
tion in the conditions of overvoltage category III.

3.2 - Installation preparation works

Fig. 2 shows an example of an automation system set up with Nice components:
a - Giro gearmotor
b - Junction box
c - Release knob (only for one way versions)
d - Control inverter or electronic control unit
e - Electrical power line
f - Spring box
These components are positioned according to a typical and usual layout. With
reference to fig. 2, establish the approximate position where each component
included in the system will be installed. Important – Before the installation,
prepare the electrical cables necessary for your system, see fig. 2.

3.3 - Installation of the gearmotor

WARNINGS
• An incorrect installation may cause serious injury to the person who
carries out the work and the people who will use the system.
• Before starting to assemble the automation, carry out the preliminary
checks described in paragraphs 3.1 and 3.2.
01. Completely close the rolling door to make the spring shaft accessible; make
a through hole with a 9 mm diameter on it (fig. 3).
02. Remove the small semi-bush by unscrewing the two M8 screws (fig. 4)
and remove the collar underneath (fig. 5).
03. Measure the diameter of the spring boxes:
- if the diameter equals 200 mm, continue with the installation.
- if the diameter equals 220 mm or 240 mm (optional), use the suitable
adapter fig. 6.

04. Measure the diameter of the spring shaft:
- If the diameter equals 76 mm, continue with the installation.
- If the diameter equals 60 mm, apply the adapters supplied (fig. 6 and 7)
220 mm 240 mm (optional)

and then continue with the installation.
- If the diameter equals 48 mm (optional), apply the adapters (optional) not
supplied (fig. 6 and 7) and then continue with the installation.
05. Position the gearmotor in the spring shaft and block it with the aid of the
collar (fig. 8).
06. Tighten the central grain (M10) making it pass through the hole made previ-
ously in the spring shaft (point 01), see fig. 9.
07. Secure the gearmotor to the spring shaft by screwing the two external
grains (M10); then, lock all three grains with the nuts (fig. 9).
08. Make a hole on the spring support shaft, to allow for the cables to pass
through it (fig. 10).
for one way versions
09. Thread the power supply cable
and the manual release cable
through the hole.
10. Then, insert the steel cable for the
manual release, into the holder
provided, by passing the terminal
through the inside of the spring
(fig. 11); then, remove the ring
and then reinsert it. For the ver-
sion with two motors, connect the
terminal of the release cable to the
spring as indicated in the figure.
11. Assemble the release knob with all the adjustment knobs tightened (A) fig.
12; then, insert the cable and, keeping it powered, lock it with the terminal
(B) fig. 12.
12. Perform the manual release manoeuvre: unscrew the lower knob clockwise
(fig. 13); manually check that the gearmotor is released. If necessary, act
on the adjustment knobs to eliminate the excess space.
13. Manually check that the gearmotor is released. If necessary, act on the
adjustment knobs to eliminate the excess space.
14. Slightly grease the teeth of the small semi-bush previously disassembled
(point 02) and assemble the two screws (M8), tightening them completely
(fig. 14). Assemble any external adapter on the semi-bush, as in point 04.
15. Make the electrical connections as shown in fig. 15.
16. On the highest part of the rolling door, make a hole with a diameter of 11
mm and secure this part in the external hole of the gearmotor fig. 16.
17. Lock down the canvas of the rolling door to the gearmotor using the screw
(M10) and washer (fig. 16).

3.4 - Limit switch adjustment

01. Carry out the manual release manoeuvre by unscrewing the lower knob
clockwise (fig. 13) then, manually make an opening and closing manoeu-
vre of the rolling door; check that the latter follows a route with a regular
and silent movement.
02. (only for one way versions) Lock the gearmotor by tightening the lower
knob anti-clockwise (fig. 18).
03. Power the gearmotor and make an opening manoeuvre; check that the rolling
door stops at the point desired. For greater precision, act on the adjusting
rollers (fig. 18). The arrow indicates the direction of the rotation (the + symbol
indicates an increase in the stroke).
04. Continue by making various attempts to find the desired position.
3.5 - (only for one way versions) Manual lock and release
procedure
Important! - The manual lock and release manoeuvres of the gearmotor must
be carried out only with the gearmotor completely stopped.
Manual operation must be carried out only in case of power failure, system mal-
functions or if expressly requested in the text of the instruction manual.
Releasing the gearmotor:
01. Loosen the lower part of the knob clockwise until you feel a certain resist-
ance (fig. 13);
02. Manually open or close the rolling door.
Locking the gearmotor:
01. Tighten the lower part of the knob anti-clockwise until you feel a certain
resistance (fig. 17).
V 10x40 Important! - If, after release of the motor, the shutter is moved manually and
the thresholds already set for adjusting the limit switch are exceeded, these will
be updated automatically with the new positions.
V 10x30

09. Thread the power supply cable
through the hole and go straight
