1.6 Installation in hazardous area
WARNING!
In case the EFS2000v4 is to be installed in a
hazardous area, as defined by the applicable
rules, it is mandatory to check if the nameplates
of the EFS2000v4 and associated ICON2000
specify that the assembly is suitable to be
installed in hazardous area with the indication of
appropriate degree of protection.
Maintenance and repair works must be carried
out by qualified personnel and checked by
responsible specialists.
The EFS2000v4 version suitable for installation
in hazardous area, with the associated electric
actuator type ICON2000 and accessories,
is designed according to all the applicable
Standards EN/IEC60079-0, EN/IEC60079-1,
EN/IEC60079-7, EN/IEC60079-11,
EN/IEC60079-31, EN 13463-1 and EN 13463-5.
