Siemens SIMATIC ET 200iSP

• The terminal module TM-PS-B via the equipotential bonding connection terminal
• Mounting rail for mounting the cable shields (with an Ex e terminal)
DANGER
Connect the equipotential bonding EB terminal correctly
The equipotential bonding connection terminal EB on the power supply module ET 200iSP
must be connected to the equipotential bonding EB according to EN 60079-14 in hazardous
areas.
According to EN 60079-14, equipotential bonding is mandatory in hazardous areas.
You can 󹪝nd more information on equipotential bonding in the system manual "Principles of
explosion protection (https://support.automation.siemens.com/WW/view/en/12521844)".
