Providing the Reference Potential when Operating Several RD500s
If devices of the RD500 series are potentially connected with each other
and/or to an external control, a central connection must be established
between the reference ground and the PE. To do this, proceed as follows:
•
Disconnect the reference ground X14.7 – PE (housing) cable connec-
tion from all converters/inverters (RD51, RD52, RS51)
•
Disconnect bridge X11.14 from X11.15 in the supply modules (RD41,
RD42)
•
Create a neutral point connection of all RD500 reference grounds
(terminal X14.7/X11.14 for each) using any existing PLC ground
•
Connect the reference ground neutral point to the PE, preferentially in
the PLC switch cabinet (if necessary, set the terminal)
