2.1.3 INTRODUCTION
Installed inside an electrical cabinet or panel, the ULYS MCM allows you to measure and monitor several electrical loads within
your production lines or the equipment in your installations for detailed analysis and diagnosis of your energy consumption.
ULYS MCM is a valuable tool for improving processes in electrical installations and making energy savings. All information
about the power supply is transmitted to the host via Ethernet and/or serial communication (RS-485). Electrical measurements
can be performed on up to 54 single-phase power supplies or 18 feeders for 3-phase 3- or 4-wire circuits or for single-phase
circuits. Thanks to this flexibility of settings, the ULYS MCM offers you an efficient system for monitoring and recording data
from electrical networks in various environments such as factories, data centres, office buildings or shopping centres. It also
allows you to carry out energy analyses and power consumption checks on lighting and HVAC systems in order to achieve real
energy savings, but also to detect possible failures to allow for proactive maintenance interventions.
2.1.4 GENERAL CHARACTERISTICS
The main characteristics of the ULYS MCM are:
 Measurement and monitoring of several electrical loads.
 Electrical measurement on up to 54 single-phase power supplies or 18 3P4F feeders - Flexibility of settings for all feeders.
 Measured electrical values: V, U, I, F, PF, Voltage and current unbalances, Power (P,Q,S) and Energies (Ea, Er, Eap).
 Accuracy class 1.0/0.5 for electrical measurements according to IEC 62053-21 / IEC 62053-22.
 Compatibility with current sensors: flexible opening sensors (Rogowski coil) and 1/3 V opening current transformers.
 Triggering of the digital output (DO) on the alarms: voltage sag / swell / overcurrent / temperature / average power.
 Temperature measurement: 1analog input terminal (NTC or 4-20 mA).

Before installing the unit:
 Check that the electrical network is disconnected and secured in accordance with electrical safety regulations.
 Check that the operating voltage and the mains voltage are the same.
Wiring must be carried out in accordance with good engineering practice. Communication lines and digital/inputs/outputs must
be separated from power supply lines. Depending on the installation, shielded cables must be used for low level signals,
connecting the shield to the reference potential.

2.3.2.1 Auxiliary power supply to appliance
The ULYS MCM does not have a switch.
An isolating device (switch or circuit breaker) must be provided in the electrical installation. The appliance must not be
positioned in such a way as to make it difficult to operate the isolating device.
The electrical installation must:
 ensure that the power supply inputs (auxiliary and digital inputs) are protected by fuses (one on phase and one on neutral)
or a circuit breaker (2 A);
 ensure that the fuses, circuit breaker or switch are correctly positioned and easily accessible;
 provide for the marking of the fuses, circuit breaker or switch as a device for disconnecting the device.
The ULYS MCM can be supplied with an AC voltage from 100 to 240 V~, and the electrical connection must be made as shown
below:
Pin no. Description
L Phase (AC)
N Neutral (AC)
2.3.2.2 Voltage measurement input
The electrical installation must ensure that the measuring inputs are protected by fuses or a circuit breaker.
Before switching on the measurement inputs, make sure that the voltage level to be connected is compatible with the electrical
characteristics of the product mentioned in the Technical Specifications (see section 2.1.5).
To measure the voltage correctly, the voltage phasing must be observed.
The connection diagram 3P4F and 3P3F depends on the position of the switches on the back of the product.
Below you will find the main connection diagrams:

2.3.2.3 Current measurement inputs
2.3.2.3.1 Precautions for use
The ULYS MCM can be connected to different types of current sensors (see section 0.2).
The ULYS MCM will have to be configured from the ULYS MCM D remote screen or from the Ulys MCM Utility software to
select the type of sensor for each channel.
The ULYS MCM can accommodate up to54 single-phase electrical feeders (3 per channel), or up to18 three-phase electrical
feeders (1 per channel). The current sensors must be of the same type for each outgoing feeder.
A channel is physically represented by an RJ12 connector as shown in the side views of the product below (example of the
ULYS MCM 18 which has 18 physical ports (9 on each side):
The channel number is indicated on the top of the ULYS MCM (the measurement channels closest to the front panel start the
numbering). For the ULYS MCM 9, channels 10 to 18 are blocked.
For the connection of current sensors measuring a three-phase electrical feeder, the following measuring chain is suggested:
RJ12 connection cables are offered by Chauvin Arnoux Energy in 3 m (ref. P01379641) and 9 m (ref. P01379642) versions. For
special arrangements with a length of more than 10 metres, please consult us.
ULYS MCM compatible current sensors are directly delivered with connectors compatible with theRJ12 adapter).
The connectors are equipped with a coding system to avoid connection errors.
It is important to observe the following instructions to ensure consistent measurement by the product:
 In the case of a three-phase connection, it is important to respect the phase order in the installation of the current collectors
in coherence with the phase order of the voltages previously wired (be sure to follow the numbering 1, 2 and 3 on the
adapter).
 In the case of a single-phase connection, the phase must be connected to terminal number 1 on the adapter.
 The direction of installation of the current sensors around the conductors to be measured must be respected (follow the
direction of the arrow on the product and the diagram above).

2.3.2.3.2 Current sensors for use with ULYS MCM
Openable flexible current sensors (Rogowski coil) type MF300 and MF3000:
USE
 Press the yellow opening device to open the flexible torus.
 Open it and place it around the conductor through which the current to be measured flows (only one conductor in the
sensor).
 Make sure that the direction of the arrow engraved on the side of the flexible torus is pointing in the direction of the current
flow in the cable.
 Close the torus. In order to optimise the quality of the measurement, the conductor should be centred in the torus and the
torus should be as circular as possible.

2.3.4 TERMINALS
2.3.4.1 Digital input and output terminals
The digital output terminal can be used as:
 Temperature alarm: if the temperature is held at its highest level for 5 seconds.
 Event alarm: in the event of voltage sag, overvoltage or temperature threshold overrun.
 Average power overrun alarm.
 Remote control.
The digital output is reset in the following cases:
 Change in the status of the event.
 Reset via the digital input terminal (DI).
The discrete input can be used to detect a change of status. The status change information can be accessed by reading in the
Modbus mapping and from the Ulys MCM Utility software.
Technical data:
 Discrete output terminal: 250 V~/5 A, 30 VDC/5A resistive (normally open state at rest).
 Discrete input terminal: 80-250 V~ status change input voltage required.
2.3.5 PORTS
To exchange with a PLC or a SCADA PC, the ULYS MCM can communicate on Ethernet or RS485 media. For more details,
please refer to the communication table (page 47).
