ELECTRICAL CONNECTIONS
WARNING! – All electrical connections must be made with the system disconnected from both the grid and the buffer battery
(if any). Incorrect connections can cause damage to the equipment and injury to people.
WARNING! – The cables used must be suited to the type of installation; for example a type-H03VV-F cable is recommended for
indoor environments, and a type-H07RN-F cable for outdoor environments.
Fig. 2 shows the electrical connections in a typical installation; Fig. 7 shows the connections to be made on the control unit.

If the power supply cable is longer than 30 m, a cable with larger gauge is required, e.g. 3 x 2.5 mm
must be arranged near the automation.

If more than one edge is present, refer to Paragraph 8.1 "STOP Input" for the type of connection recommended.

Special devices, which enable connection even when the leaf is moving, must be used to connect movable edges to sliding leaves.

For the electrical connections, proceed as described below and refer to Fig. 7:
01.
Open the cover: loosen the screw and raise the cover
02.
Feed the power cable through the relevant hole (leave 20/30 cm of free cable) and connect it to the relevant 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 fig. 7)
04.
Before closing the cover, programme the system as desired: see Chapter 7
05.
Close the cover with the relevant screw

Description
- connection input for the radio receiver antenna. The antenna is incorporated in the warning light;
alternatively an external antenna can be used, or a section of wire already present on the terminal,
which functions as an antenna, can be left
- input for devices that control the movement; it is possible to connect Normally Open (NO) devic-
es to this input
- input for the devices that block or even stop the current manoeuvre; Normally Closed (NC) con-
tacts, Normally Open (NO) contacts or fixed-resistance devices can be connected using special
arrangements on the input. For further information on the STOP function, see Paragraph 8.1 -
STOP input
- input for safety devices such as photocells. They intervene during the closing phase, by reversing
the manoeuvre. Normally Closed (NC) contacts can be connected. For further information on the
PHOTO function, see Paragraph 8.1 - Photocells
- whenever a manoeuvre is begun, the relative safety devices are all checked and the manoeuvre
only starts if the test has a positive outcome. This can only be accomplished using a special type
of connections: the "TX" photocells are powered separately with respect to the "RX" receivers. For
further information on the connection, see Paragraph 8.1 - Photocells
- on this output it is possible to connect a Nice warning light (for the relevant models see Chapter
13 - Technical specifications). During the manoeuvre the light flashes at intervals of 0.5 s
