Plant installation

The following subsections describe the installation of the required components.
WARNING
You must de-energize the plant before installation.
4.1
Cables in the powerline system and their shielding
Try to keep all cables in the powerline system as short as possible. It makes no difference
whether these are grounding cables, the cables between the PLB and the rail or the slider,
the cabling of the powerline cables in the control cabinet or the connection cables of the TC
modules.
You can install short cables with a length of less than one meter unshielded and with
2.5 mm² single cores, for example. You should still ensure that these cables are separated in
the control cabinet and that they are not installed parallel to other cables.
All cables that conduct powerline signals and are longer than one meter must always be
shielded to prevent overcoupling to other plant parts.
If you are using shielded cables, these must be connected to suitable metal parts of the plant
at both ends and in compliance with EMC. The connection of the shield must be extensive
and low-resistance, for example, over shield clamps or EMC cable glands.
WARNING
When selecting the cables, note that 230 volts can be present on the powerline rails in case
of a fault.
