Proline Promass I 100 Modbus RS485 Electrical connection
Endress+Hauser 31
For device version with device plug: only pay attention to Step 6.
1. Depending on the housing version, loosen the securing clamp or fixing screw of the
housing cover.
2. Depending on the housing version, unscrew or open the housing cover.
3. Push the cable through the cable entry . To ensure tight sealing, do not remove the
sealing ring from the cable entry.
4. Strip the cable and cable ends. In the case of stranded cables, also fit ferrules.
5. Connect the cable in accordance with the terminal assignment or the device plug pin
assignment ( 28).
6. Depending on the device version: tighten the cable glands or plug in the device plug
and tighten ( 28).
7. Enable the terminating resistor if applicable ( 32).
8. NOTICE! Housing degree of protection voided due to insufficient sealing of the
housing. Screw in the screw without using any lubricant. The threads on the cover are
