Grounding Considerations
Minimum Spacing
Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow
50 mm (2 in.) of space on all sides for adequate ventilation.
Allow at least 110 mm (4.33 in.) of enclosure depth to accommodate the module
and the DeviceNet connector.
ATTENTION:
•
The grounding screw on the front of the scanner must be connected to a suitable ground source when operating in
electrically noisy environments. Use a 2.08 mm
2
(14 AWG) wire to make this connection.
•
This product is grounded through the DIN rail to chassis ground. Use zinc plated yellow-chromate steel DIN rail to assure
proper grounding. The use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are
poor conductors, can result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately
every 200 mm (7.8 in.) and use end-anchors appropriately.
•
This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. Additional
grounding connections from the scanner's mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded. Refer to the Industrial Automation Wiring and Grounding Guidelines, publication
1770-4.1 ,
for additional information.
