Fig.:4-12 Central Connection reference ground to PE
If there is no potential control connection between the devices (e.g.
coupling using fiber optic cabler), the reference ground is directly
connected to the PE on each device.
Note: When delivered, RD 500 devices have a direct connection
between the reference ground and the PE via the X14.7 cable
connection to the housing (RD51, RS51, RD52) or via jumper
X11.14 / 15 (RD41, RD42).

Incremental encoder connection
Terminal strip X17 has a double function. When the equipment is
supplied, the terminals are used as digital inputs. This can be changed-
over to connect an HTL incremental encoder using parameter P0130
(encoder selection).
