(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 may be used for the pneumatic
power supply
•
Only suited cable entries must be used that meet the
requirements of EN 60079-15.
