Proof the correct fixing of the lead isolation.
–
Data lines must be laid isolated.
–
Analog lines must be laid isolated. When transmitting signals with small ampli-
tudes the one sided laying of the isolation may be favourable.
–
Lay the line isolation extensively on an isolation/protected earth conductor rail
directly after the cabinet entry and fix the isolation with cable clamps.
–
Make sure that the isolation/protected earth conductor rail is connected impe-
dance-low with the cabinet.
–
Use metallic or metallised plug cases for isolated data lines.
n
In special use cases you should appoint special EMC actions.
–
Consider to wire all inductivities with erase links.
–
Please consider luminescent lamps can influence signal lines.
n
Create a homogeneous reference potential and ground all electrical operating sup-
plies when possible.
–
Please take care for the targeted employment of the grounding actions. The
grounding of the PLC serves for protection and functionality activity.
–
Connect installation parts and cabinets with your PLC in star topology with the
isolation/protected earth conductor system. So you avoid ground loops.
–
If there are potential differences between installation parts and cabinets, lay suffi-
ciently dimensioned potential compensation lines.
