Grounding
If you want to mount a DataMan fixed-mount reader to a bracket or a plate, make sure that those parts make a proper
connection to ground (PE). Cognex recommends that you use lock-washers between the mounting screws and the
bracket to ensure permanent ground conductivity.
If you want to mount your reader to an electrically isolated bracket, the reader needs to be individually grounded.
For this purpose, Cognex recommends that you connect at least one of the 4 mounting holes on the bottom of the device
with a minimum 22 gauge grounding wire to system ground (PE). Use lock-washers to ensure a permanent and robust
connection.
