ELECTRICAL CONNECTIONS

Fig. 3 shows the cables needed for the connection of various devices in a
typical installation; Table 2 shows the cable characteristics.
The cables used must be suitable for the type of installation. For exam-
ple, an H05VV-F type cable is recommended for indoor applications or
an H07RN-F if fitted externally.
Connection
A: Power line
B: Flashing light
C: Aerial
D: Transmitter photocells
E: Key operated selector switch
F: Fixed edges
G: Moveable edges
H: Receiver photocells
Note 1 – Power supply cables longer than 30 m may be used provided they have a larger gauge, e.g. 4x2.5mm
the automation unit.
Note 2 – A single 4x0.25mm cable can be used instead of two 2x0.25mm

Note 3 – Use shielded cables if the length exceeds 30 m, connecting the braid to earth only on the control unit side
Note 4 – Several safety edges may be necessary in particular applications. See the instructions manual for the advised type of connection if there is more than
one edge.
Note 5 – Special devices which enable connection even when the leaf is moving must be used to connect movable edges to sliding leaves.
Note 6 – The necessary number of conductors to connect the moveable and fixed edges depends on the method used to guarantee the required safety
category. The example refers to the TCB65 edges connected to the TCE interface.
Note 7 – It is possible to connect a 230 VAC warning light. See Fig. A for the connection.
CAUTION! – The cables used must be suited to the type of environment of the installation site.
After making the electrical connections, consult Chapter 7 (DPRO500) for information on the initial start-up procedures, and recognition of the
safety devices and limit switches.
