Grounding Considerations
Set the Node Address
Use a small screwdriver to set the module’s node address switches. You must
specify a unique ControlNet node address. You can select an address of 01…99.
Address 00 is an invalid ControlNet node address.
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 (7.87 in.) and use end-anchors appropriately.
