KNX V2
Item no. 66000374 CV – 4-channel
Please read this manual carefully and keep it in a safe place!
1. Introduction:
The
CHROMOFLEX
®
Pro
KNX has been developed to control voltage controlled LEDs for up to 4 output
channels via KNX. The number of output channels, the type of dimming curve and many other settings can be easily
set using ETS-software.
2. Usage:
The modules were designed for indoor use in dry places. The LEDs might also be used in wet environments or
outdoors, if suited for that purpose. For outdoor use, be sure to use the right protection methods (IP67).
The modules must be operated with a power supply that is matched to the used LEDs! Non-LED loads (especially
inductive loads like motors, transformers, coils, etc.) might damage or destroy the module.
If any of the before mentioned points is not observed short circuit or electric shock might occur.
The
CHROMOFLEX
®
Pro
KNX was developed according to KNX Guidelines. KNX is a standardized digital
communications interface in the field of building automation.

4. Safety Instructions
The modules might produce some heat. Care must be taken to provide unrestricted air ventilation. The device
should not be warmer than 80°C in standard operation at max. load.
The unit is equipped with a limited protection against reverse polarity. Connecting the power in reverse polarity can
destroy the module, even if connected for a short time only.
When not used as directed, reversed polarity, modification of the device, for property damage or personal injury
caused by improper use or failure to observe the safety instructions, we assume no liability and the warranty
becomes void completely.
If the LEDs are provided in wet areas (e.g. swimming pools, sauna, ...) pay particular attention to the rules regarding
the power supply.
The installation of the product must be performed by a qualified electrician who is familiar with the applicable
regulations (e.g. DIN, VDE, EN).
This product is not a toy, keep away from children! LEDs can get quite hot. We strongly recommend ensuring
maximum operating temperature is not exceeded, because this might reduce the expected life time of the LEDs
significantly.
WARNING 1: LED light may have very high intensity even when dimmed. Particularly in connection with optics also
weak LEDs may be very dangerous. Staring into LEDs may cause irreparable damage to the eye's retina. Use
diffusers to spread the intensity!
WARNING 2: Please be aware that LED light may cause side effects. This light changes intensity very fast!
Changing light may affect the perception and is also known to trigger epileptic seizures in persons who are
photosensitive.
5. Installation
The electrical connection must only be carried out by a qualified electrician who is familiar with the
applicable regulations!
Caution: Turn off the power supply or the connection lead before doing any works
Assembly site
Make sure that the unit is mounted on a stable, plain, non-tilting base. In operation the unit might produce heat.
Care must be taken to provide unrestricted air ventilation.
