rearlighting through white LED) and with a 6 buttons (with preset
functions) keyboard made of silicone rubber integrated in the control-
ler, hereinafter also called built-in versions

the controller.
The devices look in case 10 DIN modules.
Installation is in electrical panel, on DIN rail.
Through the programming key EVKEY10 (to order separately) it is also
possible to make the upload and the download of the configuration
parameters.
For further information please consult the
Hardware manual of
c-pro 3.
To install c-pro 3 mega again press the DIN rail clips to the end first.
4.3 Additional information for installation
• working conditions (working temperature, humidity, etc.) must be between the limits indicated in the technical data
• do not install the controller close to heating sources (heaters, hot air ducts, etc.), devices provided with big magnetos (big speakers, etc.), locations
subject to direct sunlight, rain, humidity, dust, mechanical vibrations or bumps
• according to the safety legislation, the protection against electrical parts must be ensured by a correct installation of the controller; the parts that
ensure the protection must be installed so that you can not remove them if not by using a tool.
