Connecting the control unit with 230V single-phase power supply
Connecting the control unit with 230V three-phase power supply
Connecting the control unit with 400V three-phase power supply
2.3) Descriptions of connections:
All the connections are made by means of special terminals located
on the lower side of the electronic card. Only the power input line
should enter the upper part, directly connected to the overload cut-
out terminals.
To connect the earth circuit to the control unit and motor, use
terminals 6-7 wherever possible.
A brief description of the possible connections of the control unit outputs follows.
1-2 : Flashing light
3-4-5 : Motor
6-7 : Earth
8-9 : Phototest
10 : Open limit switch
11 : Common
12 : Close limit switch
13-14 : 24 Vac
15 : Common
16 : Gate open indicator
17 : Stop
18 : Photocell
19 : Step-by-step
20 : Open
21 : Close
41-42 : 2° Radio Ch
43-44 : Aerial
There are two additional slots on the unit card for optional cards:
RADIO
PIU
We recommend waiting until installation is complete before plugging in the optional RADIO or PIU cards.
The optional cards are not essential for system operation and, if used, they make troubleshooting more complicated.

If the control unit is powered by a single-phase system just two wires
must be connected to the first two terminals to the left of the overload
cut-out (the third terminal being unused). Connect the single-phase
motor and relative condenser as shown in figure 3a.
Take care when selecting 400V or 230V input voltage.
