Figure 6-5 Terminal block: digital input and output, reference potential
(13) Reference potential terminal
The connection "reference potential" discharges interference affecting the digital input
and output and the RJ45 connector.
Connect the reference potential to the equipotential bonding strip in the control cabinet.
