OPTICAL PORT
OPTICAL PORT: to be combined with external communication modules only
- The optical port is usable according to the device model.
- The optical port works only with a communication module of the same energy meter serie.
- The optical port ensures different communication types with the energy meter, according to the combined communication module. After making communication module connections, combine the energy meter with the module: place them side by side, perfectly lined up, with module optical port facing the meter optical port. Refer to picture E.
RS485 PORT
- The RS485 port is available according to the device model.
- The RS485 port allows to manage the device by MODBUS RTU/ASCII protocol. For device network connection, install a terminal resistance (RT=120…150 Ω) on the RS485 converter side and another one on the last device connected on the line.
- The maximum recommended distance for a connection is 1200m at 9600 bps. For longer distances, lower communication speed (bps), low-attenuation cables or signal repeaters are needed. Refer to picture F. Default values: MODBUS RTU (8N1), 19200 bps
M-BUS PORT
The M-BUS port is available according to the device model. The M-BUS port allows to manage the device by M-BUS protocol. A master interface is required between PC and the M-Bus network to adapt RS232/USB port to network. The maximum number of devices to be connected can change according to the used master interface. For the connection among the different devices, use a cable with a twisted pair and a third wire. Refer to picture G. The device can communicate when at least 2 voltage phases are connected. Default values as defined in EN 13757 standard.
ETHERNET PORT
The ETHERNET port is available according to the device model. Install the included ferrite on the Ethernet cable at a maximum 5 cm distance from the device. Make sure that the Ethernet cable is rolled twice inside the ferrite. The ETHERNET port gives the possibility to manage the device by any PC connected on the Ethernet/Internet network. In the browser web address field type 192.168.1.249, the device Web server will be displayed. The web server has been designed for two user type, Administrator for full device access (username: admin, password: admin), and User for limited device access (username: user, password: user).
Refer to picture H:
- STATUS LED: communication status; SLOW BLINKING=internal communication ok, ON=switching on or upgrading in progress, FAST BLINKING=internal communication error
- SPD LED: communication speed; OFF=10 Mbps, ON=100 Mbps
- LINK LED: link activity; ON=link ok, BLINKING=link activity
TARIFF INPUT
The tariff input is available according to the device model. The tariff management is carried out by connecting an external device to tariff input, which is providing a signal to the energy counter. The tariff signal is managed as follows:
- if the tariff input detects a voltage free signal (0 V), the device will increase the tariff 1 counters group
- if the tariff input detects a voltage signal (see Technical features), the device will increase the tariff 2 counters group
Note: Total counters increase continuously regardless from the tariff input status.
WIRING DIAGRAMS
It is suggested to install a low power switch or some fuses on the voltage inputs for protection and in order to operate on the instrument without deactivating the plant.
Refer to picture I
- 3.4.3 = 3 phases, 4 wires, 3 CTs. Available for all models.
- 3.3.3 = 3 phases, 3 wires, 3 CTs. Available only for PULSE and M-BUS models.
- 3.3.2 = 3 phases, 3 wires, 2 CTs. Available only for PULSE and M-BUS models.
Before instrument power ON, check if all connections are made in a proper way. Make sure that the voltage and current terminals are connected correctly. Moreover, make sure that low voltage ports, such as communication ports and/or SO ports, are connected to low voltage lines. These safety precautions may reduce the risk to damage the instrument in case of improper connections.
