5.5 Electrical connection
Risk of fatal injury due to electric shock.
Î
For electrical installation, you are re -
quired to observe the relevant electro -
technical regulations of the country of
use as well as the regulations of the local
power suppliers.
Therefore, such work must be performed by
trained and experienced personnel.
Î
Do not connect ELV cables (according to
VDE 0100) to these terminals.
Î
Before performing any work on the ter -
minals, disconnect the voltage supply
from the industrial controller.
DANGER !
Notes on electric wiring
Î
Install the power supply lines and the sig-
nal lines separately. Do not install them
parallel to each other.
Î
To improve noise immunity, observe a
minimum distance of 10 cm between the
power line and the measuring input line.
Î
To avoid measurement errors or other
disturbances, use shielded cables for the
analog and binary signal lines. Ground
the shield at one side, either at the con-
trol cabinet inlet or outlet, using the larg-
est possible cross-section.
Î
Connect the central grounding point and
the PE grounding conductor with a cable
with ≥10 mm² wire cross-section using
the shortest route.
Î
Inductances in the control cabinet, e.g.
contactor coils, must be equipped with
suitable interference suppressors (RC ele -
ments).
Î
Control cabinet elements with high field
strength, e.g. transformers or frequency
converters, must be shielded with sepa-
rators providing a good ground connec-
tion.
The industrial controller has plug-on screw
terminals for lines with a wire cross-section
from 0.5 to 1.5 mm². Connect the lines to
the terminal blocks 1 and 4 (see Fig. 5-5,
Fig. 5-6 and Fig. 5-7).
Î
Plug the plug-on screw terminals securely
into the appropriate connector sockets in
the controller.
