Connection concept for voltage and current inputs
The voltage and current input signals are connected directly to the 14-pole cage
clamp terminal (E0 … E6 and COM). To minimize the amount of noise coupled into
the module via the transmission lines, connection should be made according to the
principle explained below.
The following connection diagram shows a typical wiring layout for:
●
voltage inputs with the PCD3.W305 and PCD3.W325 modules or
current inputs with the PCD3.W315
●
If screened cables are used, screening should be continued to an external
earthing bar
