Caution
Before connecting the power supply lines make sure that the device is operated with the correct supply
voltage (see device rating plate)!
First you connect the grounding cable to the PE terminal, then the actual supply lines at the power supply
terminal block.
Incoming and outgoing PROFIBUS cables are connected to terminal A (green wire) and B (red wire) re-
spectively.
Terminals L and H must not be connected (CAN bus, for internal use only).
Note To ensure safe operation of the assembly and to reduce EMC interference to a minimum, the cable shield
of the PROFIBUS lines should be connected to the corresponding terminals in the connection box.
For additional EMC interference suppression the housing grounding screw (M6 thread) should be used
to establish a low-resistance connection (wire cross-section 4 mm²).
Note When disconnecting the PROFIBUS cable from the unit, the entire bus connection is interrupted!
Device versions with interruption-free disconnection capability: see next section.
