Warning
If the recommendations in this manual are incompatible with instructions for a given
device, the device instructions should be followed. As regards EMC, safety rules
take precedence.
Because of rapid changes in industrial electronics, problems with Electromagnetic
Compatibility (EMC) can no longer be ignored. Care must be taken when connecting
devices (equipment in a network, automatic control devices, remote inputs/outputs,
etc.) so that they fulfill the functions for which they were designed, even in an
environment with electromagnetic disturbances.
Thus this document was written for:
b Engineering and design departments, who must plan the use of communications
cables (connecting terminals, length of wiring, definition of topology,etc.)
b Those who implement Modbus, to help them install communications cables.
b Integrators, who must take communications into account in applications that
include SCHNEIDER products.
