Install the DIN Rail
Mount the DIN rail in a suitable location.
ATTENTION: 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.
