Cable and wiring entries (CWE)
● When fitting cables, observe the manufacturer's data on the tightening torques of the
cable and wiring entries.
● Use the tightening torque of the clamping screw when connecting the cables.
● Relieve the tension on the cables outside the enclosure so that the cable gland is not
stressed.
● For additional information and technical specifications, refer the respective manufacturer
documentation, in particular:
– Technical specifications, clamping ranges for cables
– Notes on use, installation, mounting, commissioning and maintenance
Use the supplied red dummy plugs to close any cable glands not in use. Only then is it
ensured that the degree of protection is retained.
Equipotential bonding rail
The equipotential bonding rail (10 x 3 mm) with terminals (up to 4 mm²) is used to contact
the cable shields. Alternatively, you can also use other terminals here, e.g. KLBüCo from the
company Weidmüller (not included in the scope of delivery)
Connect the equipotential bonding wire to the bonding terminal (0.75 to 35 mm²).
Short lines connect the equipotential bonding rail to the mounting plate and thus to the
enclosure. In cases where the ground and equipotential bonding conductors are installed
separately, this connection can be disconnected.
Also observe the installation guidelines in the ET200iSP operating instructions, Section 5.2
"Using ET 200iSP with equipotential bonding".
Screw the wall supports onto the enclosures using M6/M8 screws depending on the
enclosure size. These are included with the enclosure accessories. To secure the enclosure,
use 8 mm diameter screws and lock washers.
The M6/M8 ground connection screw is used for the PE conductor; use a cable with lug for
this. To prevent the screw from becoming loose, make sure you use the lock washer.
Connecting the grounding cable avoids static charge which is important, in particular, for
dust explosion protection.
