Information on the safe use in hazardous areas
Function and features
• Use in hazardous areas according to the classification
(Group II, category 1 G / 2 G, apparatus for gas atmosphere).
The unit conforms to the requirements of EN50014, EN50020, EN50284
and EN60947-5-6.
• EC type test certificate
• Marking
Installation / Setup
Only qualified staff with a knowledge of protection classes, regulations and
provisions for apparatus in hazardous locations may install, connect and set up
the units.
Check whether the classification (see "Marking" above and marking on the
unit) is suitable for the application.
• Connection only to intrinsically safe certified circuits or evaluation amplifiers
which do not exceed the following maximum values of the units:
• The wiring is indicated in the technical data sheet or on the type label.
• Permissible operating temperature of the application (referred to the maxi-
mum permissible power of 120 mW):

• Maximum effective internal inductance (Li) and capacitance (Ci):
The values apply to potted cables.
Articles with cable / units with cable
NN****) For cable units with potted different cable lengths the values of
the cable must be taken into account:
1.2 µH (Li) / 50 pF (Ci) per metre of potted cable.
*1) Thus the maximum effective internal inductance of the unit results in:
Li = 130 µH + cable length in (m) X 1.2 µH.
*2) Thus the maximum effective internal capacitance of the unit results in:
Ci = 140 nF + cable length in (m) X 0.05 nF.
Installation remarks / Mounting
• Adhere to the relevant national regulations and provisions.
• Avoid electrostatic charging from plastic units and cables.
• Protect the units efficiently against damage.
• The cable must be laid fixed and protected efficiently against damage.
• The units are not suitable for installation in walls which separate zone 0
from zone 1.
• The relevant installation regulations EN60079-14, EN50039 must be
adhered to.
• Steps must be taken to ensure the equalisation of potential of metal parts
(also fixing material).
Maintenance / Repair
The unit must not be modified nor can it be repaired. In case of a fault please
contact the manufacturer.
If needed, you can obtain data sheets or EC type test certificates from the man-
ufacturer (see cover sheet).
