Mechanical digital feedback
(Limit1: +51 / −52)
(Limit2: +41 / −42)
Special conditions
• Devices must only be connected to circuits in zone 2 if they
are suitable for operation in zone 2 potentially explosive
atmospheres and for the conditions prevailing at the
installation location (manufacturer's declaration or
certificate from an inspection authority).
• For the 'digital feedback with proximity switches' circuit,
external measures must be implemented to prevent the
rated voltage from being exceeded by more than 40 % in the
event of transient disturbances
• 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 suited cable entries must be used that meet the
requirements of EN 60079-15.
