Note that only one of the RS232 or RS485 connectors can
have a cable connected at any one time in order to comply
with Class B EMC emission standard (EN61000-6-3,
residential, commercial, and light industrial environments).
WARNING: Failure to comply with this requirement will
reduce the unit to Class A (industrial environments); in a
domestic environment the unit may cause radio interference,
in which case the user may be required to take adequate
measures.

This diagram shows IQ3 wired as a master,
it may also be wired as a slave.
If the IQ3/XNC/SER controller and other units on the bus are
in the same cabinet using the same power supply, each device
should have a good physical earth (ground) connection.

If the IQ3/XNC/SER controller and other units on the bus are in different cabinets or use different power supplies (e.g. different
UPSs), the cabinets should be isolated from each other. If the bus is likely to suffer from surge and grounding problems, surge
protection should be added. The isolator should be connected to the earth (ground) of the nearest device, the 0V of the isolator
and the surge protector should be connected together, and earth (ground) of the surge protector’s exposed side (e.g. backbone
bus) should be connected as directly as possible to the surge ground or earth bond.
