6.4Connecting the equipotential bonding circuit

A low resistance ground connection ensures that interference signals generated by external power supply cables, signal cables or cables to the I/O modules are safely discharged to ground.

The equipotential bonding connection of the device is located on the right-hand side of the computer unit and is identified by the following symbol:

Figure 6-1 Equipotential bonding

Connecting the equipotential bonding circuit

You require a TORX T20 screwdriver to connect the equipotential bonding conductor.

Steps for connecting the equipotential bonding
(1) Connect the equipotential bonding connection (M4 thread)
(1) on the device (large surface, large-area contact) with the
central grounding point of the control cabinet.
The minimum permissible cross-section is 5 mm2.
