Examples for connections:1. Shielding of serial coupling to controller in double sided contact.With additional equipotential bonding lead (10mm² required).PLCMTEquipotential leadCentralpointgroundingAs a rule, double sided contact will result in the optimal damping of all connected interference frequencies.The power supply to the machine terminal may also be through the supply of the PLC.2. Shielding the serial coupling to controller through single sided contact.Without equipotential bonding lead.PLCMTPotential differenceCentral groundingpointIn this case, the equipotential flow would be across the shielding, if the shield connection was double sided.This must definitely be avoided, since the resulting interference impulses could be fed into the devices via thedata input lead.Where shielding is single sided, the shield connection must be made on the side of lowest impedance as nearas possible to the central grounding (connection A in the example).Before commissioning, it is necessary to check the installation instructions specified by the manufacturer for safeoperation. They should be reconciled with the recommendations here.Screen connection with MT-30:Via 6.3 mm flat connector (not included in delivery).Process display and control/ Device Manual/ Issue: 07.0123E
