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.
