3Description of the Smart Master G3
The Smart Master G3 is a 3-in-1 smart meter that can measure three charges, such as photovoltaic
production, the total consumption of a building or the consumption of an electrical device. The
product is equipped with a built-in relay capable of controlling an electric charge.
The meter has several connectivity options for Internet: by Ethernet RJ45 cable, by PLC plug or by
cellular modem (option). It also has external connections: such as an RS485 port and two Ethernet
ports.

5Internet connectivity options
The Smart Master G3 operates with an Internet connection. This product can be connected to the
Internet by an Ethernet cable, by PLC or by a modem.
Choose the means of connection to the Internet before wiring the product.
Switch on the device before running the connection tests (refer to the electrical connections
and commissioning chapters).
REMINDER: the device is communicating properly over the Internet when the power light is green.
CAUTION: if the Ethernet cable connected to the MG3 is outside the IPX4 casing, the operating
voltage must be at least 300 V. Also, make sure that the cable does not touch any exposed live
surfaces inside the casing.
5.1 Ethernet cable connection
The device has an Ethernet LAN connector for a direct connection to the internet router.
The LAN LED comes on and flashes when a connection is established.
5.2 PLC plug connection
5.2.1 Ethernet cable on the Internet router
If the Internet router is a long way from the electrical system and is not equipped for PLC, the
device can be connected to the Internet through a PLC plug (P/N: MLSH-COM-1).
PLC communication uses the electrical wiring in the housing, and no additional cables are
necessary (for single- or three-phase power supplies).
RJ45 cable

The steps to connect the PLC plug:
-Switch off the Internet router
-Connect the PLC plug to the wall socket next to the Internet router
-Use the Ethernet cable provided to connect the PLC plug to your Internet router (refer to
your Internet access provider’s documentation for more information). Use only one of the
Ethernet ports numbered 1 to 4 on the back of the router. Do not use the fibre port or any
other ports.
-Switch on the Internet router by connecting it to the available socket on the back of the PLC
plug
-The two PLC devices (the MG3 and the PLC plug MLSH-COM1) are paired automatically in
1 to 15 minutes.
(refer to paragraph 3 to check the proper operation)
5.2.2 Wi-Fi connection on the Internet router
A Wi-Fi repeater can be used to connect to the router to establish Wi-Fi communication between
the Smart Master G3 and the Internet router. Recommended P/N: WA850RE
The connection is shown below.
