Note 1 – Power supply cables longer than 30 m may be used provided they have a larger gauge, e.g. 4x2.5mm
2
, and a safety earthing system is provided near
the automation unit.
Note 2 – A single 4x0.25mm
2
cable can be used instead of two 2x0.25mm
2
cables.
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 xed 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.

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 tted externally.
