SINGLE-PHASE NETWORK ANALYSER
Read all instructions carefully
A series of single-phase system analysers for TRMS (True Root Mean Squared) values:
- ANRET M-22 for direct connection of current leads having I
- ANRET M-22-BUS with serial output RS 485 for both direct connection of current leads
having I = 22,5A and current connection by way of external ATs type x/5A
MAX
SAFETY INSTRUCTIONS
To guarantee correct installation, observe the following instructions:
1) The instrument must be installed by a qualifi ed person
2) The instrument must be installed in an electrical panel which, after installation, leaves
terminals inaccessible
3) The building in which the instrument is installed must have an electrical system
including a switch or a circuit breaker: this must be near the device and in a position
that can be easily reached by operators.
4) A protection device against over-currents must be installed in the electrical system
upstream of the instrument
5) Connect the instrument as shown in the diagrams of this manual
6) Before making contact with terminals, ensure that leads to be connected to the
instrument are not live
7) Do not power or connect the instrument if any part of it is damaged
Note: The network analysers in the ANRET M-22 series are aimed for use in places with
overvoltage category III and pollution degree 2 to EN 61010-1.

The partial meter is automatically zeroed when the scale range is overrun. To set the meter to
zero manually, hold the "SEL" key down for more than 3 seconds
To view the fi rst page again, press the SEL key once more.
BACKLIGHTING
The device's display backlights when the SEL key is pressed: it stays on for 30 seconds after the

SETUP OF EXTERNAL ATs (for M-22-BUS model only)
To view the AT setting, go to page 2 and hold down the SEL key for at least 3 seconds.
To change the AT setting, proceed as follows.
Hold the SEL key down while switching the device on: the display will read in a sequence the
fi rmware version, the serial number and will fl ash the AT primary value. To select an AT different
than the fl ashing value, press the SEL key repeatedly until the desired value appears.
The AT values available are as follows: 5/5A, 10/5A, 25/5A, 50/5A, 75/5A, 100/5A, 125/5A, 150/5A,
200/5A, 250/5A, 300/5A, 400/5A, 500/5A, 600/5A, 800/5A, 1000/5A.
To effect the change, select the AT value and then press the SEL key until the value stops
fl ashing. The partial energy count will then be zeroed and the voltage page (page 1) will appear
on the display.
Note: If direct connection of current leads is used (I
value) in the AT setting.
SERIAL-COMMUNICATION CONFIGURATION (for M-22-BUS model only)
The following serial-communication parameters can be accessed: address number, baud rate and
parity.
To read the current serial parameters, go to page 3 and hold the SEL key pressed for at least
Total active energy meter 3 seconds, until the address page appears. To scroll the other pages push the SEL key: after
viewing the last page the display resumes normal reading.

press it again to change it and then confi rm by pressing it long, until the value stops fl ashing.
OPERATING MESSAGES
PHASE ERROR
Frequency value
On startup the device checks whether the current and voltage terminals are connected correctly.
In case of error the phase error page will be displayed for 3 minutes. The triangular LED on the
left will fl ash.
Total active energy meter
Partial active energy meter
To resume correct operation, turn it off, invert voltage or current connections, and turn on
again.
Non-zeroable total active energy meter
Error conditions occurring during normal operation are indicated by the fl ashing of the
triangular LED on the left. Voltage, current and frequency values are nonetheless read correctly.
Zeroable partial active energy meter
As for the remaining pages, energy counts will not increase, the power factor will be force-set to
1 and the active power value to 0.
OVERFLOW ERROR
When the voltage or current reading range is overrun, the relevant fi eld will fl ash dots and the
total energy count will be read.
Backlighting status (ON / OFF)
Voltage or current overfl ow error is indicated on the other pages too. in this case the values
measured will fl ash.
SERIAL COMMUNICATION
The instrument (M-22-BUS model only) has an insulated serial output RS 485.
• The data communication system is based on MODBUS protocol (RTU coding system) and can
be connected to a Master system (PC/PLC...) on a multipoint line RS 485:
- up to 31 ANRET (slaves) without signal amplifi ers, from a maximum distance of 1000 m
- up to 247 ANRET (slaves) in groups of 30 separated by proper signal amplifi ers
Current AT value
• Contact the technical assistance service dept. to request documents regarding MODBUS
functions, use of registers and the ANRET-view software.
