ELECTRICAL CONNECTIONS
CAUTION! - All electrical connections must be carried out with the system disconnected from the mains. Incorrect connections
can cause damages to the equipment and injuries to people.
Fig. 2 shows the hookup of a typical installation; g. 7 shows the connections to be made on the control unit.

Function Description
9 - 10 Stop - input for devices that lock or stop the current operation; with appropriate precautions, “Normally Closed” or
“Normally Open” contacts or constant resistance devices can be connected to the input.
Other information on STOP can be found in paragraph 8.1.1 - STOP input
9 - 11 Photo - input for safety devices which when tripped reverse the gate's direction of movement: NC (Normally Closed)
contacts may be used
- for further details, refer to par. 8.1.2 Photocells.
8 - 12 Phototest Every time a manoeuvre is started, the operation of the photocells is checked; the manoeuvre starts if the test
is positive. This is possible using a particular type of connections: the transmitters of the “TX” photocells are
powered separately than the “RX” receivers.
For further details, see paragraph 8.1.2 Photocells.
9 - 13 Step-by-step input for devices which control movement. NO (Normally Open) contacts can be connected
4 - 5 Flashing light - asher output (auto-intermittent)
- when active, the output supplies 230 V~ (120V~ on V1 / motor version)
1 - 2 Aerial - radio receiver aerial input
- aerial integrated into asher; an external aerial can be used if desired
To make the electrical hookup, proceed as described below with reference to g. 7:
01. Open the cover: undo the screw and raise the cover
02. Run the power cable through the hole (leave 20/30 cm of free cable) and connect it to its terminal clamp
03. Run the cables of the equipment to be installed or already present through the provided hole (leave 20/30 cm of free cable) and connect
them to their terminal clamps (see g. 14)
04. Perform the desired programming: chapter 7
