Complete the following steps to mount the CN2DN device on a DIN rail.1.Align the CN2DN device over the DIN rail.
2.Press the CN2DN device onto the DIN rail until the DIN rail latches lock the linking
device in place. 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 every200 mm (7.8 in.) and use end-anchors appropriately.
WARNING: This equipment shall be mounted in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54 (as defined in IEC60529) and used in an environment of not more than Pollution Degree 2 (as defined in IEC 60664-1) when applied in Zone 2 environments. The enclosure must have a tool-removable cover or door. IMPORTANTThe DIN rail must be properly grounded. See publication Industrial Automation Wiring andGrounding Guidelines, publication
