8 Electrical connection
CAUTION!
For the wiring and connection of the controller, you are required to observe the VDE re -
gulations and the regulations of the local power supply company. For this reason, this
type of work must be carried out by a specialist.
When installing the electrical lines, please note the following:
4
Use separate cables for the 230-V supply lines and the signal lines! To increase the noise
immunity observe a minimum distance of 10 cm between the cables! This separation in
space is also applicable to the cables within a control cabinet!
4
Also use separate cables for the digital signal lines (bus lines) and the analog signal lines
(sensor lines, analog outputs).
4
For systems with a high electromagnetic noise level, we recommend that shielded cables
be used for the analog signal lines. Ground the shield one-sided at the inlet or outlet of
the control panel, using large-area contacts! The central grounding point must be con -
nected to the grounding conductor via a cable
≥
10 mm 2 using the shortest possible
route.
4
Inductances in the control cabinet, e.g. contactor coils, must be equipped with suitable
interference suppressors (RC elements)!
4
Control cabinet elements with a high field strength, e.g. transformers or frequency con -
verters, should be shielded by means of separators that have good chassis ground.
Surge protection measures
4
If signal lines are routed outside buildings or over large distances, you are required to
take suitable surge protection measures! For bus lines, such measures are essential.
4
The shield of signal lines that are routed outside buildings, must have current carrying ca -
pacity and grounded on both sides.
4
The surge diverters must be installed at the control cabinet inlet.
