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.
Note
Also observe the installation guidelines in the ET200iSP operating instructions, Section 5.2
"Using ET 200iSP with equipotential bonding".
Wall supports
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.
Grounding connection
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.
Installed components
The enclosure nameplate specifies the parameters within which the installed components can
be used.
Observe the following if you subsequently connect equipment and the required cables on site:
● Read and observe the manufacturer's instructions, especially notes, warnings and
information on special features.
● Electrical equipment as well as combinations of equipment can impair the intrinsic safety
of the circuits as a result of their electrical parameters. Prior to installing equipment, check
that the intrinsic safety of the circuit is still guaranteed.
