2.3) List of cables
Figure 2 shows the cables needed for the connection of the devices in a typical installation; table 5 shows the cable characteristics.
The cables used must be suitable for the type of installation; for example, an H03VV-F type cable is recommended for indoor
applications, while H07RN-F is suitable for outdoor applications.
Note 1: power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2,5mm
2
, and that a safety grounding sys-
tem is provided near the automation unit.
Note 2: If the “BLUEBUS” cable is longer than 30 m, up to 50 m, a 2x1mm
2
cable is needed.
Note 3: A single 2x0,5mm
2
cable can be used instead of two 4x0,5mm
2
cables.
Note 4: Please refer to Chapter “7.3.2 STOP Input” in situations where there is more than one edge, for information about the type of con-
nection recommended by the manufacturer.
Note 5: special devices which enable connection even when the leaf is moving must be used to connect movable edges to sliding leaves.
