DIN Rail Grounding
The DIN Rail must be connected to a ground bus or grounding electrode
conductor using 8 AWG or 1 inch copper braid. The grounding wire can be
connected to the DIN rail using a DIN Rail Grounding Block (
Figure 2.2 ).

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.
