ATTENTION
POINT I/O is grounded through the DIN rail to chassis ground.
Use zinc-plated, yellow-chromated steel DIN rail to assure proper
grounding. The use of 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.).
