Introduction
5. Introduction
The T2S ETH stands for T2S Ethernet. It replaces the former T2S with the same form factor but with a front Ethernet
connector replacing the former USB one. Like his predecessor, T2S ETH is a monitoring solution for the full TSI inverter
range and is able to monitor up to 32 inverters through a friendly web base interface. T2S also supports Modbus Serial
communication (RTU) and SNMP v1 Communication.
This new monitoring device provides a graphical user interface, embeds a SNMPv2c/SNMP v3 agent and Modbus TCP
support with Catena, if one needs a touch screen display Catena can be connected to T2S ETH and is Compatible. It
also allows user to change the configuration of the system.

13 – Monitoring T2S - ETH User Manual – v1.4
Hardware
6. Hardware
T2S ETH provides 3 LEDs: Red for major alarm signaling, orange led for minor alarm signaling and green led for power
and network connection status.
The RJ45 is a standard ETH connector that could be connected on any IPv4 network.
T2S ETH firmware can be upgrade using the Micro SD card. Device firmwares are available in my.cet-power.com

6.2 Signaling Information
As it is designed to be used in the same shelf as former T2S, T2S ETH inherits the connections on the back.
Note: The terminal connector accepts maximum wire size of 0.5 mm2.
Important remarks:
In a system with several shelves, T2S ETH is usually located in the first one (although it’s not mandatory) but relay
signaling contacts will be terminated in the T2S ETH installed shelf. The above connection is just an example, actual
connection will be based on your shelf design and connections.
If the T2S is included in one complete system including for example Termination box or some customers packages, the
terminal will be located somewhere else. (Refer System user manual).

16 – Monitoring T2S - ETH User Manual – v1.4
Hardware
6.2.1 Alarm relay
There are 3 alarm contacts:
•Major
•Minor
•User selectable
As one can see in the picture: contacts 5 and 6 are closed when no major alarm is present,
contact 8 and 9 are closed when no minor alarm is present.
Remark: Default mapping and level of each available alarm of the monitoring unit is
available in “Annex 1: Supervisor alarms - T2S ETH”, page 69.
NB: Alarm relay are active (energized) when no alarm are present.
•Alarms relay features
Max current: 2 A @ 30 VDC or 1A @ 60 VDC
Max Power: 60 W
Max Voltage: 60 VDC SELV
Note that for higher voltages, it is mandatory to install an additional relay with appropriate characteristics – especially
for 60/110/220 VDC.
6.2.2 Digital Inputs
Two potential free Digital inputs are available for customer connections.
•Digital Input 1 is assigned for MBP operation if used.
•Digital Input 2 is assigned for Surge Arrester if used.
The voltage present on terminal 1 and 3 is +5 V (galvanic insulation). Care should be taken to avoid connecting any
external voltage on terminal 1 to 3. External signals should be applied to these terminals via Volt-free contacts. The
function is activated when the 2 terminals concerned are short-circuited (i.e. when the external Volt-free contact is
closed).
6.2.3 Communication
A RJ45 connector is present at rear of the shelf and can be used for Candis display and Modbus (RTU) communication.

17 – Monitoring T2S - ETH User Manual – v1.4

Important remark:
T2S ETH comes in only one “flavor” in term of serial communication RS485 and support Modbus RTU (read-only).
Currently, no protocol is available for customer use on CAN bus connection and it is dedicated for Candis accessory.
The unregulated +12 V power supply is designed for powering CE+T accessories and should not be used for any other
purpose.

18 – Monitoring T2S - ETH User Manual – v1.4
Hardware
6.3 Monitoring - Candis
T2S ETH also supports the Candis display and it is a monitoring device allowing the user to get
information from inverter system.
To enable candis, connect RJ45 CAT cable at rear side of the T2S ETH installed shelf and
Candis. Refer section 6.2.3, page 16.
6.3.1 Display and Buttons
1 Display (2 lines provided to display information).
2 Up button to scroll UP in the menus.
3 Down button to scroll DOWN in the menus.
4 Enter button to change display or validate modifications.
6.3.2 Conguration
When more than one display is used on the same system, the CANBUS ID must be different and include values from
124 to 264 (i.e as 134; 144 ; 154, …264).
The other information that can be configured are the related phase, the AC group or DC group, and the adjustment the
backlight.
If the installed system is multi-phase or has multiple DC groups, the T2S and the inverter modules must be correctly
configured to display the correct value by phase or DC group.
For instance in three phase systems, the inverter modules must be configured to show the 3 phases’ output
information, but also the one related to the three AC group who correspond to each AC input phase. By doing so, the
display will show the values phase by phase.
Warning: The Candis Display is powered from the auxiliary power supply of the modules which are
limited in power.
