iNELS CU3-08M Guest Room Controller User Manual

Characteristics

CU3-08M is one of the basic system control units of iNELS BUS installations.
The unit can work independently, as an autonomous project, or it can be controlled by the IP-MASTER as part of a larger project.
The units is equipped with two BUS to which it on each bus up to 32 iNELS BUS units can be connected.
The current load of one line is max, 1 A, BPS3-01M with 3 A canbe used incase of connected device with more than 1 A.
The RJ45 100 Mbps Ethernet connector is used for direct communication with the cloud for mobile app control or for communication with the superior unit within the iNELS IP topology.
Confi guration takes place in the iNELS3 Designer & Manager software (iDM3).
Through iDM3 it is possible to update the fi rmware of central units and bus connected peripheral units.
The units is powered by 27 V DC from inels power supply.
System units CU3-07M in 1-MODULE design are designed for mooting into a switchboard on DIN rail EN60715.

CU3-08M

Installation BUS:

Two-wired BUS with an arbitrary topology (not only to be as closed ci cle).
With its own modulated communications on the DC voltage supply.
One line of BUS allows you to connect up max. 32 units of iNELS3. The current load of one line is max. 1 A. When connecting units which draw greater than 1A, power supply PS3-100 iNELS and BPS3-01M with max. 3 A sampling can be used.
Maximum length of the BUS is approximately 300 m (depends on the voltage drop).
Recommended cable:
- iNELS BUS Cable – Twisted pair of copper wires with size of AWG20 wire (diameter of 0.8 mm, cross-section of 0.5 mm2).
The confi gurations of units and the whole system are done via Ethernet, through confi guration software – iNELS3 Designer & Manager (iDM3), which is designed for operating systems Windows 10 and Windows11.
The central unit features two communication protocols:
- ELKONET – to communicate with Connection Server or directly with the application iHC.
Supported Software:
- Parameterization, confi guration, control and visualization: iNELS3 Designer & Manager (iDM3).
By means of iDM3, you can update fi rmware of central units and peripheral units connected by BUS.

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. In the course of inspections and maintenance, always check (while de-energized) if terminals are tightened.

DECLARATION OF CONFORMITY
ELKO EP declares that the CU3-08M type of equipment complies with Directives 2014/30/EU, 2011/65/EU, 2015/863/EU and 2014/35/EU. The full EU Declaration of Conformity is available at: https://www.elkoep.com/central-unit-minicu- cu3-08m
