4.3 ELECTRICAL CONNECTIONS
Attenzione
!
•
The operator shall always be protected upstream by a 6A automatic differential switch with 30 mA actuation point and
contact opening over 3 mm.
•
The electrical installation shall be in compliance with the regulations in force in the installation country.
•
Do not use intercom or phone cables.
4.3.1 Useful advice
1. For the connection to the power source, use a cable with a minimum cross-section of 2 x 1.5 mm
2
.
2. For the controls (
open - common - close
) and (centralised open - common - centralised close and safety contact),
use cables with a cross-section of 3 x 0.25 mm
2
for lengths less than 5 metres; or cables with a cross-section
of 3 x 0.5 mm
2
for lengths over 5 metres.
3. For extensions of the motor power cables, use cables with a minimum cross-section of 2 x 0.75 mm
2
for lengths less
than 5 metres; or cables with a minimum cross-section of 2 x 1.5 mm
2
for lengths over 5 metres.
4. For extensions of the electric stop cables, use cables with a minimum cross-section of 2 x 0. 5 mm
2
for lengths less
than 5 metres; or cables with a minimum cross-section of 2 x 1 mm
2
for lengths over 5 metres.
4.3.2 Connecting the motor cables
Double-wing
•
Loosen the four cross-slotted screws on the corners of the box containing the electronic card and open the cover
• Shut the two wings and check which of them rests on the other (i.e. check which one closes second), then take the
red-black wires of the corresponding geared motor (indicated as
Mot1
) and proceed as follows:
A)- Fit the wires of gear motor (
Mot1
) that will close last (wing above) into the cable bushing
B)- Disconnect the removable 8-pole terminal board (
M2
) positioned on the right in the lower part of the electronic
card and connect the
red
wire to terminal
6
and the
black
wire to terminal
7
.
C)- Take the red-black cable of gear motor (indicated as
Mot2
) and, after having inserted it into the cable bushing,
connect the
red
wire to terminal
9
and the
black
wire to terminal
8
of the removable terminal board (
M2
).
Single-wing
For the connections of the single-wing, use only the connection to gear motor (
Mot1
).
4.3.3 Connecting the control accessories
Local controls -
Insert the cable into the cable bushing, then connect the wires to terminal board (
C2
) as
shown in the fi gure.
1
= open
2
= close
3
= common
Centralised controls and safety contact -
Connect the wires on the terminal board (
J2
) as shown in the fi gure.

• centralised
closing
• safety
• common
4.3.4 Connection to the power network
Take the power cable (not standard supplied) and insert it into the bushing of the control unit box.
Remove terminal board
