Example for shielding both ends of the connection cables from the PLC to the light curtain
Ground the transmitter housing and receiver housing of the light curtain (see chapter "Grounding the
Only lay shielded light curtain cables to the PLC.
Clamp the shield flat to FE in the PLC (see figure 7.3).
Use special shielding terminals (e.g., Wago, Weidmüller, …).
Make certain that the mounting rail is well grounded.
