Special conditions
• For the 'Limit monitor with proximity switches' circuit,
measures outside of the device must be implemented to
prevent the rated voltage from being up-scaled by more than
40 % due to 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 hazardous atmosphere would be present in
Zone 2 at the same time that installation, maintenance or
repair work was being carried out.
• Only non-flammable gases may be used for pneumatic power
supply.

• Only use suited cable entries that meet the requirements of
EN 60079-15.
