6.2.6 Modbus Ethernet connection (option)
The digital communications terminals are separated from the
analyser main circuit by reinforced insulation. The terminals
must only be connected to circuits that are themselves
separated from mains voltages by an isolation method that
provides at least this level of protection.
Les terminaux de communication numériques sont séparés du
circuit principal analyseur par une isolation renforcée. Les
bornes ne doivent être raccordés à des circuits qui sont eux-
mêmes séparés des tensions d'alimentation par une méthode
d'isolement qui fournit au moins ce niveau de protection.
The instrument can be supplied with Ethernet digital communications as an option.
For a full list of what can be communicated over the Modbus communications see
Appendix 13A3.
If Modbus Ethernet option is supplied:
