4 Safety regulations and installation notes
4.1 Installation notes
– The device is an item of associated equipment
(category 1) with “intrinsic safety” protection type and
can be installed in zone 2 potentially explosive areas as
a category 3 device.
It meets the requirements of
EN 60079-0:2012, IEC 60079-0 Ed. 6.0,
EN 60079-11:2012, IEC 60079-11 Ed. 6.0
EN 60079-15:2010, IEC 60079-15 Ed. 4.0
Installation, operation, and maintenance may only be
carried out by qualified electricians.
Follow the installation instructions as described.
When installing and operating the device, the
applicable regulations and safety directives (including
national safety directives), as well as general technical
regulations, must be observed.
For the safety data, refer to this document and the
certificates (EC examination certificate and other
approvals if appropriate).
– Do not open or modify the device. Do not repair the
device yourself; replace it with an equivalent device
instead. Repairs may only be carried out by the
manufacturer.
– The IP20 degree of protection (EN/IEC 60529) of the
device is intended for use in a clean and dry
environment. Do not subject the device to mechanical
or thermal loads that exceed the specified limits.
– The device complies with the EMC regulations for
industrial areas (EMC class A). When using the device
in residential areas, it may cause radio interference.
4.2 Intrinsic safety
– The device is approved for intrinsically safe (protection
type Ex i) circuits up to zone 0 (gas) and zone 20 (dust)
in the hazardous area.
Observe the safety values for intrinsically safe
equipment and the connecting cables during
connection (IEC/EN 60079-14). They must conform to
the values specified in the installation manual, in this
data sheet, or the EC-type examination certificate.
– When carrying out measurements on the intrinsically
safe side, observe the relevant regulations regarding
the connection of intrinsically safe equipment. In
intrinsically safe circuits, only use those measuring
devices that are approved for these circuits.
– If the device has been used in non-intrinsically safe
circuits, it must not be used again in intrinsically safe
circuits. The device must be clearly marked as non-
intrinsically safe.
4.3 Installation in the hazardous area (zone 2)
– Observe the specified conditions for use in potentially
explosive areas!
Install the device in a suitable approved housing (with at
least IP54 degree of protection) that meets the
requirements of EN 60079-15. Observe the
requirements of EN 60079-14.
– Always disconnect the power before connecting or
disconnecting non-intrinsically safe cables.
– In potentially explosive areas, always disconnect the
power before snapping the device on or off the DIN rail
connector.
– The device must be stopped and immediately removed
from the hazardous area if it is damaged or was
subjected to an impermissible load or stored incorrectly
or if it malfunctions.
4.4 Areas with a danger of dust explosions
– The device is not designed for installation in zone 22.
– If, however, you wish to use the device in zone 22, it
must be installed in a housing that complies with
IEC/EN 60079-31. In doing so, observe the maximum
surface temperatures. Observe the requirements of
IEC/EN 60079-14.
– Connection to the intrinsically safe circuit in areas with
a danger of dust explosions (Zone 20, 21 or 22) is only
permitted if the equipment connected to this circuit is
approved for this zone (e.g. Category 1D, 2D or 3D).
4.5 Safety-related applications (SIL)
When using in safety-related applications, observe the
instructions in Section 7, as the requirements differ for
safety-related functions.
