NOTE
Different manufacturers do not always interpret the standard on which the RS485 protocol is based
in the same way. Note that the wire designations (- and +) for wires A and B can vary between manu-
facturers.
NOTE
Calculating efficiency 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.
