Standards EN 60079-0, EN 60079-11
Special conditions
• The power supply for the 'Feedback on the actuator
position using proximity switches (Pepperl & Fuchs SJ2-
SN)' circuit must be provided intrinsically safe in
accordance with the PTB 00 ATEX 2049 X / RU C-
DE.AA87.B.00394 certificate according to application
type 2.
• It is only permissible to connect, disconnect, and switch
live circuits during installation or maintenance, or for the
purpose of carrying out repairs.
Note
It is considered very unlikely that a potentially hazardous
atmosphere would be present in Zone 2 at the same time
that installation or maintenance or repair work was being
carried out.
• Only non-flammable gases must be used for pneumatic
power supply.
• Only use suited cable entries that meet the requirements
of EN 60079-11.
