NOTE: For the electrical connections see paragraph "ELECTRICAL CONNECTIONS" on the instruction sheet
"Ex d electric actuator" (CPS19 .... - CPS25 ....).
3.3 - INSTALLATION IN PLACES WHERE THERE IS THE RISK OF EXPLOSION (DIRECTIVE 2014/34/EU)
The solenoid valve complies with Directive 2014/34/EU as a device of group II, category 3G and as device of group II, category
3D; consequently, it is suited for installation in zones 2 and 22 as classified in Annex I of Directive 99/92/EC. The solenoid
valve is NOT suitable for use in zones1, 21, 0 and 20, as defined in aforementioned Directive 99/92/EC. To determine the
qualification and size of the hazardous zones, please refer to standard IEC EN 60079-10-1.
If installed and subject to maintenance in full compliance with all conditions and technical instructions provided in this manual, the
device does not pose a source of specific hazards: in particular, under conditions of normal operation, it is not expected for the
solenoid valve to emit a flammable substance into the atmosphere with methods such as to originate an explosive atmosphere.
During installation and maintenance, it is imperative to comply with the Ex standards, in particular EN 60079-14. Electrical
installation must be carried out by authorised personnel in accordance with relative national regulations.
