NPM800 – NPM800R

NPM800RE

Date : 05/2013

Edition :30/01/2014

Folio : 57

Indice : g

10. Connection of the Modbus RS485 communication

10.1 Characteristics of the network cable

Recommended characteristics for the cable:

•

Shielded twisted pairs, maximum length 1000 m.

•

resistance < 100 ohms/km

•

capacity between wires < 60 pF/m

•

capacity between wire and shield < 100 pF/m

The NP800 and NP800R relays are fitted with one fixing clamp to hold the network cable and
recover the shielding of the network cable:

- the network cable must be stripped

- the shielding braid of the cable must be in contact with the clamp

In order to ensure continuity of the cable and its earthing, check that the fixing clamp is
tightened on the shield recovering the jacket.
