Description
4.6 Details of the enclosure
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.
Note
Also refer to the installation guidelines in the SIMATIC ET 200iSP Operating Instructions, section
5.2 "Operating the ET 200iSP with potential equalization".
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 ground connection screw is used to connect the ground cable. Use a cable with cable lug
for this purpose. To prevent the screw from becoming loose, make sure you use the lock washer.
Connecting a ground cable prevents static charging.
Installed components
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.
Note
If you want to replace ET 200iSP reserve modules with ET 200iSP modules, please contact
Siemens regarding the rated current and power loss calculation.
