Notes
| Safety Information | Adjacent devices of the same type are devices of the same design (series) that are arranged next to one another on the DIN-rail with the same orientation. An end stop (249-116) must be fitted to devices of other types for compliance with the reinforced insulation requirements. |
| Note | Terminals 6 (GND) and 8 (GND) are internally bridged. The maximum current-carrying capacity is 4 A. |
