1. INTRODUCTION
You have just purchased an ULYS FLEX MODBUS. Thank you for your choice. To get the best from your device:
• Read this user’s manual before installing and using the device.
• Follow the precautions for use stated in this document.
Symbol Meaning
HAZARD WARNING! The operator must consult this manual whenever this danger symbol is
encountered.
This symbol indicates compliance with European directives, including LVD and EMC.
This symbol means that in the European Union, the product is subject to separate collection in
accordance with WEEE 2002/96/EC: this material should not be treated as household waste.
Information.
• Make sure the device is intact and undamaged upon receipt. In the event of any problems, please contact
the after-sales department for any repairs or replacements.
• The device described in this manual is intended to be used by trained staff only.
• Any maintenance operations must be carried out by qualified and authorized personnel only.
• For correct and safe use and for all maintenance operations, it is essential that staff follow standard safety
procedures.
• This device is intended to be used in Category III installation and pollution degree 2 conditions in accordance
with standard IEC 61010-1.
• Before installation, check that the supply voltage matches that of the mains supply network.
1.1 SAFETY PRECAUTIONS
Safety precautions
Before any intervention, check that the device is unplugged from all power sources.
Precautions against electrical noise
Although the ULYS FLEX MODBUS is protected from electrical and electromagnetically induced interference,
keep away from theimmediatevicinityof equipment generating significant electricalnoise(high-powerswitches,
busbars, etc.). The quality of data communication on the data bus depends heavily on taking such precautions.
Precautions in the event of deterioration
When safe operation is no longer possible, the instrument must be switched off and isolated. This applies when:
• the device is visibly damaged during operation (whether the device still operates or not),
• the device does not work after prolonged storage in poor conditions,
• the device no longer works following severe damage during transport.
Cleaning instructions
When the device is disconnected from the mains, clean the outer surface using only a dry cloth. Do not use
abrasives or solvents. Prevent the connector terminals getting wet.

2. GRAPHIC SYMBOLS
In this manual, some instructions are highlighted with graphic symbols to alert the reader to possible danger.
These symbols are:
DANGER! This symbol warns of the presence of dangerous voltage (even for short moments)
on the indicated points.
WARNING! This symbol alerts you to the possibility of a serious incident or damage to the unit
if proper precautions are not taken.
NOTE. This symbol indicates the presence of important information that should be read carefully.
3. PRELIMINARY VERIFICATION
NOTE. At the opening of the box, check that the instrument has not been damaged during
transport. If the instrument appears to be damaged, contact the technical after-sales service.
The box contains:
• the instrument
• the quick guide
• no. 3 Rogowski coils
4. GENERAL DESCRIPTION
The instrument is a digital meter able to measure the electrical parameters on three-phase systems. It provides
accurate measurements even by distorted waveform.
LCD display provides the three-phase quantities. The working parameters can be easily set up by instrument
keypad.
The instrument is a compact, cost effective meter operating both as a stand-alone device or as an integral part
of a more extensive energy monitoring and management network.
Theinstrumentreplacesmultipleanalogmetersas well as single functionmeters such asvoltmeters,ammeters,
wattmeters, varmeters, frequency-meters, powerfactor-meters, energy-meters, etc.

5. INSTALLATION
NOTE. The equipment complies with the 89/366/EEC, 73/23/EEC standards and following
amendments. However, if not properly installed, it may generate a magnetic field and radio
interference. This is why compliance with EMC standards on electromagnetic compatibility is
essential.
5.1 ENVIRONMENTAL REQUIREMENTS
The environment in which the instrument is installed must satisfy the following features:
• indoor area
• operating temperature between -25°C and +55°C
• max humidity 80% (no condensation)
• up to 2000 m over sea-level altitude
NOTE. The instrument must not be exposed to sun rays.
5.2 MOUNTING
Fastening to DIN rail (EN 60715) is provided for the instrument.
To mount it on the DIN rail, use a screwdriver as a lever on the plastic hook at the instrument bottom. This
operation will allow the instrument to fit on the rail.
6. SAFETY MEASURES
DANGER! This warning means that a dangerous voltage may be present on the terminals even
for short periods.
WARNING! Electrical instrument connections must be carried out only by skilled technicians
who are aware of the risks involved to the presence of voltage.
Before connecting, check the following:
1. The conductor wires are not powered.
2. The instrument is connected according to the appropriate diagram.
3. The power supply corresponds to the values on the instrument specification.
4. The instrument has been installed in a vibration-free and a suitable temperature environment.
5. The terminals are no longer accessible after being connected.
6. The wiring is carried out in accordance with the standards in force in the Country where the instrument
will be installed.
7. A circuit breaker and an over-current device (eg. 250 mA T type fuse) are installed between the instrument
power supply and the electrical system.
8. The connections are made respecting the polarities.
- L1 of the voltage input = L1 of the amperometric input.
- L2 of the voltage input = L2 of the amperometric input.
- L3 of the voltage input = L3 of the amperometric input.
9. Input and output polarities are respected when using Rogowski coils.
10. The terminals are fixed in such a way that the connection wires cannot be accidentally disconnected.

7. ELECTRICAL CONNECTIONS
WARNING! The instrument installation and use must be carried out only by qualified staff.
Switch off the voltage before device installation.
7.1 CURRENT AND VOLTAGE INPUTS
DANGER! This section describes the measurement voltage and current inputs susceptible to
dangerous voltage levels.
WARNING! Before carrying out connections, check if there is no voltage/current in the conductor
wires. DO NOT CONNECT conductors under voltage/current.
