Grounding
All devices are equipped with a metal housing. They comply with safety class I and require a
protective earth connection. The connecting cable for the operating voltage must contain a protective
earth wire of a sufficient cross section (DIN VDE 0106 part 1, DIN VDE 0411 part 1).
EMC measures
The devices comply with the current EU Directive (EMC Directive) and provide the required
interference immunity. Observe the following when connecting the operating voltage and data cables:
Use shielded data cables.
The data and operating voltage cables must be laid separately. They may not be laid together with
heavy-current cables or other interference-producing cables.
The cable thickness must be properly assessed (DIN VDE 0100 Part 540).
The cable lengths inside the units are to be kept as short as possible to prevent interference. This
applies especially to unshielded operating voltage cables. Shielded cables are also to be kept short
due to any interference which might be emitted by the shielding.
Neither excessively long cables nor cable loops may be placed inside the units.
The connection of the cable shielding to the functional ground (PE) must be as short and low-
impedance as possible. It should be made directly to the mounting plate over a large area with a
conductive clip:
①
mounting plate
②
conductive clamp
③
data lines
④
cable shielding
The cable shielding is to be connected at both cable ends. If equipotential bonding currents are
expected due to the cable arrangement, electrical isolation is to be performed on one side. In this
case, capacitive connection (approx. 0.1
μF/600 V AC) of the shielding on the isolated side must occur.
Disposal
Units or unit parts which are no longer needed are to be disposed of in accordance with the
regulations in effect in your country.
