Notes before connecting
In order to avoid moisture in the meter due to condensate
build-up, acclimatise the meter at room temperature for
about half an hour before connecting.
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 energy meter can be attached to a 35 mm rail
(EN60715TH35).
The meter can be used only in installation cabinets.

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 Even parity: 8 data bits, 1 stop bit
Odd parity: 8 data bits, 1 stop bit
No parity: 8 data bits, 2 stop bits
Bus length (max.) 1200 m (without repeater)
Response time: Write: up to 60 ms
Read: up to 60 ms
■
The communication is ready 30 s 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 5 s. For this reason one energy meter should be not polled faster as 5 s
■
247
devices could be connected to the Modbus. With more than 128 devices, a repeater should be used
■
The interface don’t have a terminal resistor, this must 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.
Changing the Modbus address direct on device
■
In the menu, go for «U»
■
Push long ( ≥ 3 sec) ➞ «Adr»
■
Push short ➞ address +1, push long ➞ address +10
■
Once the desired address is selected wait, to validate, till the root menu to come back

Register
For double registers (4 – 5, 16 – 17, 28 – 29, 30 – 31) the high register is sent rst (big-Endian).
Partial counter (30 – 31) can be reset by writing 0 in both registers in the same message.
