Risk of electric shock!
−
For electrical installation, you are required to observe the relevant electrotechnical regula
-
tions of the country of use as well as the regulations of the local power suppliers. Make
sure all electrical connections are installed by trained and experienced personnel.
−
The terminals 25 and 28 allow safety equipment which have a direct influence on
individual electric actuators to be integrated. If an internal power supply is to be used,
connect a jumper from terminal 18 to terminals 25 and 28. Do not connect ELV wiring
(according to VDE 0100) to these terminals.
−
Before performing any work on the controller, disconnect it from the power supply.
Notes on electric wiring
−
Install the 230 V power supply lines and the signal lines separately! To increase immuni-
ty, keep a minimum distance of 10 cm between the lines. Make sure the minimum dis-
tance is also kept when the lines are installed in a cabinet.
−
The lines for digital signals (bus lines) and analog signals (sensor lines, analog outputs)
must also be installed separately!
−
In plants with a high electromagnetic noise level, we recommend using shielded cables
for the analog signal lines. Ground the shield at one side, either at the control cabinet in-
let or outlet, using the largest possible cross-section. Connect the central grounding point
and the PE grounding conductor with a 10 mm² cable using the shortest route.
−
Inductances in the control cabinet, e.g. contactor coils, are to be equipped with suitable
interference suppressors (RC elements).
−
Control cabinet elements with high field strength, e.g. transformers or frequency convert-
ers, must be shielded with separators providing a good ground connection.
Overvoltage protection
−
If signal lines are installed outside buildings or over large distances, make sure appropri-
ate surge or overvoltage protection measures are taken. Such measures are indispens-
able for bus lines.
−
The shield of signal lines installed outside buildings must have current conducting capaci-
ty and must be grounded on both sides.
−
Surge diverters must be installed at the control cabinet inlet.
