Grounding
The VersaMax PROFINET Scanner has a separate shield ground connection to provide
shielding for its two ports. Attach a wire with a stab-on connector to the grounding terminal
on the bottom of the module.
Figure 9
Connect a ring terminal on the other end of the wire to a grounded enclosure. Where the
ring terminal contacts a painted enclosure panel, either install a star lock washer between
the terminal and the panel to cut through the paint, or scrape the paint away down to clean,
bare metal to ensure a good contact.
Note:
The star lock washer method is suitable for a shield ground, but not suitable for a safety
ground.
