The HTG411L is a multi-energy data logger and server
delivered with a 4GB micro SD card. It is intended to
configure systems and products, collect, store and time
stamp information for connected products. It processes
this information and monitors the quality of the electrical
distribution and makes it available to the user through an
embedded webserver. This product is accessible from
the Internet network.
This device is to be installed only by a
professional electrician fitter according
to local applicable installation standards.
Do not install this module outside the
building.
Power supply over Ethernet (PoE) prohi-
bited.
In «Setup ON» mode, the HTG411L acti-
vates its DHCP server on «Setup - Ether-
net 1» port.
Installation
The HTG411L must be fitted on a DIN rail.
Implementation
1. Connect the inputs / outputs on the HTG411L termi-
nal block.
2. Connect the Modbus and Ethernet networks as
appropriate.
3. Enable 120 Ω termination resistor (selector (2) to
set to «ON») if the product is fitted at the end of the
Modbus network.
4. Check that the selector «Setup» (1) is in «OFF»
position.
5. Connect the 24 V s power supply (SELV).

First configuration
1. Start the software update:
a) download the latest software version from
https://hgr.io/r/htg411l
b) unzip the downloaded file
c) read the file «readme.txt»
2. Connect the computer to the RJ45
«Setup - Ehernet 1» connector of HTG411L using
the Ethernet cable.
3. Turn switch «Setup» (1) in «ON» position.
4. Perform a reset by switching the power
supply off and again on.
5. Activate the Web browser on the computer.
6. Enter: url : https://192.168.0.1
7. Setting the HTG411L, refer to the user guide, down-
loadable from https://hgr.io/r/htg411l website or
with the Datamatrix scanning.
The energy server has two operating modes:
- Stand-alone mode : The server is still the master
component in the installation and obtains measure-
ments from connected meters.
- Supervised mode: The server is used as a gateway to
send data to the Energy Management System stream.
Several functions in the menus are inaccessible in this
mode (see user manual).
Switch to supervised mode
1. Go to the Preferences menu.
2. Select the System tab.
3. In the Supervised mode section, check yes to
enable the mode.
4. Click on Save.
When the energy server is rebooted, it restarts in
supervised mode.
