Notes before connecting
1. Do not connect L1, L2 or L3 to N
2. In order to avoid moisture in the meter due to condensa-
te build-up, acclimatise the meter at room temperature
for about half an hour before connecting.
3. N must always be connected.
Attention!
These devices must only be installed by a professional
electrician, otherwise there is the risk of re or the risk of
an electric shock.

Installation instructions
The three-phase energy meter can be attached to a 35 mm
rail (EN60715TH35).
The meter can be used only in installation cabinets.
Operation of the LCD display
See page with LCD menu navigation.
The bridge Z1-Z2 should be removed for adjusting the
transformer ratio.

Technical data Modbus
Bus system Modbus, RTU according to IDA specication
Transmission rate 4800-9600-19'200-38'400-57'600-115'200.
The transmission Baud rate is automatically detected
Transmission mode No parity: 8 data bits, 1 stop bit
Bus length (max.) 1200 m (without repeater)
Response time: Write: 60 ms
Read: 60 ms
■
The Interface works only if the phase 1 is connected.
■
The communication is ready 30s after the power on
■
The use of energy meter in Bus with intensive communication could reduce the performance of the Bus
■
Refresh time for the data is 10 s. For this reason one energy meter should be not polled faster as 10s.
■ 247
devices could be connected to the Modbus. Over 128 devices, a repeater should be used.
■
The interface don’t have a terminal resistor, this should be provided external.
■
For a description of the used registers please look at the register page
Data transmission
■
Only «Read Holding Registers [03]/ Write Multiple Registers [16]» instructions are recognized.
■
Up to 20 Registers can be read at a time.
■
The device supports broadcast messages.
■
In accordance with the Modbus protocol, a register R is numbered as R - 1 when transmitted.
■
The device has a voltage monitoring system. In case of voltage loss, registers are stored in EEPROM (transmission rate, etc.)
Exception Responses
■
ILLEGAL FUNCTION [01]: The function code is not supported.
■
ILLEGAL DATA ADDRESS [02]: The address of some requested registers is out of range
or more than 20 registers have been requested.
■
ILLEGAL DATA VALUE [03]: The value in the data eld is invalid for the referenced register.
Change the Modbus address direct on device
■
To modify the Modbus address, press 3 s on ► touch
■
In menu, ▼ increase address by 10, ► increase by 1
■
Once the address is selected wait for the root menu to come back

The Modbus Address register is not writable with a broadcast message.
Wiring diagram
The secondary, mains current transformer
connection is to be connected to the phase to
be measured and therefore the transformer
don’t have to be grounded.
This connection is to be fused according to the local
installation instructions.
