Grounding When Using a DIN Rail (Master 810/2410)

If you are using DIN rail adapters instead of the rack mount brackets, you must ensure that the Master is properly grounded by connecting a ground cable to one of the holes indicated below. The holes on the bottom of the unit accept M4 screws. The holes on the sides of the unit accept M3 screws.

You can use any of the holes shown below. However, LMI recommends using the holes indicated on the housing by a ground symbol.

An additional ground hole is provided on the rear of Master 810 and 2410 network controllers, indicated by a ground symbol.
