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!
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 is cooled by natural and forced convection, but it is necessary in a rack or in a junction box
to ensure adequate air fl ow. In case the air access is restricted, cooling must be ensured by a fan.
Rated operating ambient temperature is 50 °C. It is always necessary to keep a gap on each side
of the dimmer with a minimum width of at least one module. In the course of inspections and
maintenance, always check (while de-energized) if terminals are tightened and air fl ow is suffi cient.

The principles connecting the LED light sources to the unit DCDA-33M:
- Before connecting the LED utilising a potentiometer regulate the fl ow to the respective channel
to a minimum.
- The DCDA-33M is designed for serial or series-parallel connection of LED chips connected without
precipitating resistance.
- Never connect one LED chip (or two LED chips) alone! This will destroy these LED chips. Always
connect a series of at least three LED chips, so that the condition U
on the source. It is necessary that the LED chips are in the working area, see graph U
a general overview the table is used to calculate the voltage drop on a single LED chip.
- While connecting the LED chips measure the size of current through the ammeter and using a
potentiometer to set the desired value.
- Where the documentation of the LED chip specifi es a voltage higher than 6.5 V. The LED chip can be
attached to a DCDA-33M separately.
- Curves in the graph above, determine the limits of the LED.
- Example: An LED chip can be used for an 18 V power with a voltage drop from 6.5 - 14.5 V. This corresponds
e.g. Serial wiring 3-5 pcs green LED chips (LED chip loss is 3 V, see table, the resultant voltage is thus 9-15 V)
per channel. Chart conditions must always be met for the smallest U
- With a series-parallel connection of LED chips, always connect the same number of LED chips in
each parallel branch.
- ATTENTION! U (max) curve exceed! This can destroy the LEDs!
n
- Un voltage may be lower than U (min), but if it is not possible to set the output to set the desired
n
current LED chip (chips) may not light at all.
- Individual channels can be combined to increase the current up to 4 or 6 A.
