NOTICE
Diff erent manufacturers do not always interpret the standard on which the RS485 protocol is based in the
same way. Note that the wire designations (DATA- and DATA+) for wires A and B may vary from one manu-
facturer to another.
NOTICE
Calculating effi ciency by measuring the current and voltage values can lead to misleading results due to
the tolerances of the measurement devices. The sole purpose of these measured values is to monitor the
basic operation of the system.
