• 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).
