Wiring diagram 3
Design with changeable
temperature sensors, LoRa interface
and 24V power supply module.
The 24V power supply module is
mounted on the battery holder and
connected to the B1 connector of
the meter.
A backup battery is connected to
the BAT connector of the module.
The 24V power cable is connected
to the "24V" terminals of the
module (connections are made
before mounting the module, as
the connectors and terminals are
on the other side of the module).
The LoRa interface module is
connected to the 24V power supply
module connector by an additional
connection cable.
