Information

c Please, read carefully these instructions before proceeding with the installation of
the controller.
NOTES Class II instrument, rearl panel mounting.

ON ELECTRIC This controller has been designed with compliance to:

SAFETY AND Regulations on electrical apparatus (appliance, systems and installations) according to
the European Community directive 73/23/EEC amended by the European Comunity direc-
ELECTROMAGNETIC tive 93/68/EEC and the Regulations on the essential protection requirements in electrical
COMPATIBILITY apparatus EN61010-1 : 93 + A2:95.

Regulations on Electromagnetic Compatibility according to the European Community

directive n089/336/EEC, amended by the European Community directive No. 92/31/EEC,
93/68/EEC, 98/13/EEC and the following regulations:
Regulations on RF emissions
EN61000-6-3 : 2001 residential environments
EN61000-6-4 : 2001 industrial environments
Regulation on RF immunity
EN61000-6-2 : 2001 industrial equipment and system

It is important to understand that it’s responsibility of the installer to ensure the compliance
of the regulations on safety requirements and EMC.
The device has no user serviceable parts and requires special equipment and specialised
engineers. Therefore, a repair can be hardly carried on directly by the user. For this purpose,
the manufacturer provides technical assistance and the repair service for its Customers.
Please, contact your nearest Agent for further information.
All the information and warnings about safety and electromagnetic compatibility are
marked with the B sign, at the side of the note.
