Figure 9-8 shows the additional grounding for a bus coupler using the example of the
IL PB BK DI8 DO4-PAC bus coupler. Connect the additional grounding to your device
according to the terminal-specific documentation.
The modules have an FE spring (metal clip) on the bottom of the electronics base. This
spring establishes an electrical connection to the DIN rail. Use grounding terminals to
connect the DIN rail to protective earth ground. The modules are grounded when they
are snapped onto the DIN rail.
Phoenix Contact also recommends grounding the Inline Block IO module via the
FE terminal point of the corresponding connector to ensure reliable functional earth
grounding even if the DIN rail is dirty or the metal clip is damaged (see terminal-specific
data sheet).
