8 Mounting and Installation
The device is approved for use in gas explosion hazardous areas of Zones 1 and 2 and
dust explosion hazardous area of Zones 21 and 22 and in safe areas.
DANGER
Explosion hazard due to installation without field enclosure!
Non-compliance can result in severe or fatal injuries!
• If used in Zone 1, the device must be installed in an enclosure that
meets the requirements of IEC/EN 60079-11.
• If used in Zone 2, the device must be installed in an enclosure that
meets the requirements of IEC/EN 60079-15.
• If used in Zone 21 and 22, the device must be installed in an
enclosure that meets the requirements of IEC/EN 60079-31.
DANGER
Explosion hazard due to incorrect installation of the device!
Non-compliance results in severe or fatal injuries.
• Carry out installation strictly according to the instructions and
national safety and accident prevention regulations to maintain the
explosion protection.
• Select and install the electrical device so that explosion protection
is not affected due to external influences, i.e. pressure conditions,
chemical, mechanical, thermal and electric impact such as
vibration, humidity and corrosion (see IEC/EN 60079-14).
• The device must only be installed by trained qualified personnel
who is familiar with the relevant standards.
If the installation has strong electromagnetic sources of interference or
the electric lines are more than 30 m long, use of shielded field cables is
recommended to achieve the specified data. To this end, the shield must be
connected to the equipotential bonding of the hazardous area and connected
to the shield busses in the enclosure as close to the entry point as possible!
The shield busses must also be connected to the mounting plate close to the
entry point of the field wiring using the shortest possible route!
