IMPORTANT
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 (e.g. aluminum, plastic, etc.) 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 (7.87 in.) and use
end-anchors appropriately.
