On battery or renewable energy versions, do not leave an RS232 connection plugged in or
wired with voltages applied unnecessarily. Such voltages result in far higher power consumption
from the battery or backup source, limiting battery / backup life.

Note. The serial port connection shares the same physical port as the MODBUS connection so
(depending on cable design) it may be necessary to disconnect the MODBUS connection temporarily to
enable configuration of AquaMaster 3.
