Warning
Before the device is installed and operated, read this instruction manual carefully and with full
understanding and Installation Guide System iNELS3. The instruction manual is designated for
mounting the device and for the user of such device. It has to be attached to electro-installation
documentation. The instruction manual can be also found on a web site www.inels.com. Attention,
danger of injury by electrical current! Mounting and connection can be done only by a professional
with an adequate electrical qualifi cation, and all has to be done while observing valid regulations.
Do not touch parts of the device that are energized. Danger of life-threat! Temperature sensor
input on the potential of the mains voltage - beware the possibility of electric shock. It is therefore
necessary to use a sensor possessing double or reinforced insulation for the overvoltage category
according to EN 60664-1 (eg sensor TC, TZ). While mounting, servicing, executing any changes,
and repairing it is essential to observe safety regulations, norms, directives and special regulations
for working with electrical equipment. Before you start working with the device, it is essential to
have all wires, connected parts, and terminals de-energized. This instruction manual contains only
general directions which need to be applied in a particular installation. To ensure correct function
of the dimmer, its cooling is important. The dimmer creates temperature loss approx 1.5% from
installed output. For instance when output is 1000 W the temperature loss is 15 W. Dimmer is
cooled by a natural air fl ow and therefore it is necessary to ensure such air fl ow in the switchboard.
In case the air access is restricted, cooling must be ensured by a fan. Rated operating ambient
temperature is 35 °C. In case of installation of more dimmers in one line, there has to be a space
in-between them – minimally 2 cm. In the course of inspections and maintenance, always check
(while de-energized) if terminals are tightened and air fl ow is suffi cient.

General instrucions
CONNECTION TO THE SYSTEM, INSTALLATION BUS
iNELS3 peripheral units are connected to the system through the BUS installation. Installation
BUS conductors are connected to the terminal units to BUS+ and BUS- terminals, wires cannot be
interchanged. For installation of BUS it is necessary to use a cable with a twisted pair of wires with
a diameter of at least 0.8 mm, the recommended cable is iNELS BUS Cable, whose features best
meet the requirements of the BUS installation. Bearing in mind that in terms of all the properties
is it is possible in most cases also use the cable JYSTY 1x2x0.8 or JYSTY 2x2x0.8, however it
is not recommended as the best option. In the case of a cable with two pairs of twisted wires
it is not possible to use the second pair of the other for modulated signal due to the speed of
communications; it is not possible within one cable to use one pair for one segment BUS and the
second pair for the second segment BUS. For installation of BUS it is vital to ensure that it is kept
at a distance from the power lines of at least 30 cm and must be installed in accordance with its
mechanical properties. To increase mechanical resistance of cables we recommend installation
into a conduit of suitable diameter. BUS topology installation is free except for the ring, wherein
each end of the bus must terminate at the terminals BUS + and BUS- peripheral unit. While
maintaining all the above requirements, the maximum length of one segment of the installation
BUS can reach up to 500 m. Due to the data communication and supply of units in one pair of wires,
it is necessary to keep in mind the diameter of wires with regards to voltage loss on the lead and
the maximum current drawn. The maximum length of the BUS applies provided that they comply
with the tolerance of the supply voltage.
INSTALLATION RECOMMENDATIONS
Assure suffi cient device cooling. Due to the large number of light sources, the maximum load
depends on the internal design of dimmable LEDs and ESLs and their eff ect cos φ.
The eff ect of dimmable LEDs and ESLs fl uctuates within a range of: cos φ = 0.95 to 0.4. The
approximate value of the maximum load is attained by multiplying the dimmer load carrying
capacity with the power factor of the connected light source.
DEVICE SETTING
Setting the minimum brightness: the minimum brightness is set when the load is switched on by
turning the minimum brightness potentiometer to the required value. The minimum brightness is
saved around 3 seconds after performing the last change in the potentiometer position.
Setting the load type: the load type is set when the load is switched off by turning the light source
selection potentiometer to the required value.
CAPACITY AND CENTRAL UNIT
It is possible to connect to the central unit CU3-01M or CU3-02M two independent BUSes by means
of terminals BUS1+, BUS1- and BUS2+, BUS2-. It is possible to connect to each BUS up to 32 units,
so it is possible to connect directly to the central unit a total of 64 units. It is necessary to comply
with the requirement of a maximum load of one BUS line - maximum up to 1000 mA current. When
connecting units which draw greater than 1A, BPS3-01M with 3A sampling can be used. It is the
sum of the rated currents of the units connected to the BUS line, other units can be connected
using the units MI3-02M, which generate further BUSes. These are connected to the CU3 unit via
the system BUS EBM and you can connect a total of 8 units via EBM BUS to the central unit MI3-02M.
SUPPLYING THE SYSTEM
For supplying power to system units, it is recommended to use the power source of ELKO EP titled
PS3-100/iNELS. We recommend backing up the system with backup batteries connected to the
source of PS3-100/iNELS (see sample diagram of connecting the control system).
DESCRIPTION OF DEVICE PROTECTION STATUS
The DA3-22M device features protection from overheating, short-term and long-term overloads:
- Thermal protection: activates upon constant output load, or insuffi cient device cooling. The
protection switches off the output until the dimmer cools down to its operating temperature.
The dimmer can then be switched back on. Remove faults by providing better dimmer cooling,
by decreasing the power consumption of the connected load, or by switching to the correct
light source position.
- Short-term overload: activates by short-term high overload, ex. by temporary short circuit.
Protection appears by short fl ashing of the connected load. Remove faults by decreasing the
power consumption of the connected load, or by switching to the correct light source position.
- Long-term overload: activates by constant short circuit, or output overload caused by excessive
amount of connected load. The protection switches off the device, and it is possible after 5
minutes to switch the dimmer back on. Remove faults by decreasing the power consumption
and by specialized inspection of the wiring distribution.
GENERAL INFORMATION
The unit is capable of working as an independent element without a central unit only in very limited
scope of its functions. For full utility of the unit, it is necessary for the unit to be connected to the
central unit of the system CU3-01M, or to a system that already contains this unit as its expansion
to include further system.
All unit parameters are set through the central unit CU3-01M in the software iDM3.
There are LED diodes on the unit front panel, for indication of supply voltage and communication
with the central unit series CU3. In case that the RUN diode fl ashes at regular intervals, so there is
standard communication between the unit and BUS. If the RUN diode lights permanently, so the
unit is supplied from BUS, but there is no communication between BUS and unit. In case that RUN
diode is OFF, so there is no supply voltage on the terminals BUS+ and BUS-.
Attention: The temperature sensor input is at the potential of the network supply voltage - beware
the possibility of electric shock.
ADDITIONAL INFORMATION
Energy-saving lamps not explicitly marked as dimmable cannot be dimmed. Incorrect setting
of the light source type only infl uences the range and course of dimming (meaning no damage
occurs to either the dimmer or load). Incorrect setting of the load type may cause the dimmer
to overheat. The maximum number of dimmable light sources depends on their internal design.
