4.9 AC meter connection
AC meters from various manufacturers can be used during installation. In next chapters will be described
most common ways how to connect it to Pixii system.
4.9.1 AMS energy meter
Pixii controller is not equipped with M-Bus port, therefore USB to M-Bus converter (optional kit) needs
to be used. Connect it to free USB port on Pixii controller and connect Ethernet cable to RJ45 connector
on converter. On meter side are 2 possible options for connecting communication cable. If only Pixii
controller will be connected to AC meter, connect Ethernet cable directly to RJ45 connector on meter.
Otherwise connect short cable with RJ45 splitter to AC meter and then to splitter connect Ethernet cable
from Pixii controller. For more information, see installation guide DN 14754 (14754_Installation guide -
HAN to USB converter).
4.9.2 Industrial grade energy meter
Modbus/RTU
All supported AC meters are equipped with RS485 port for communication. Therefore 2-wire bus must
be wired between meter and Pixii controller. Use the customer spare terminals -X5/-X6 extension
function. Connect AC meter to the terminals -X5, and controller serial port to the terminals -X6. For more
information, see chapter
Figure 4.28 Industrial AC meter connection
Modbus/TCP
All supported AC meters are equipped with RJ45 port for communication. Therefore ethernet cable must
be connected between the meter and the switch. Pixii controller must be connected with ethernet cable
to the same switch as the meter to ensure the correct communication.
NOTE:
Pictures above are showing only examples of AC meters.
