Wiring with Tank Side Monitor NRF590
L00-NRF590-04-08-08-yy-007
The Mircopilot S is - possible in combination with other devices - connected to a Tank Side
Monitor in a hazardous area. In this case, it is recommended that you ground the cable screen
centrally at the Tank Side Monitor and connect all other devices to the same potential matching
line (PML). If, for functional reasons, a capacitive coupling is required between local earth and
screen (multiple grounding), ceramic condensers with a dielectric strength of min. 1500 V
eff
must be used, whereby the total capacitance of 10 nF must not be exceeded. Notes on grounding
interconnected intrinsically safe devices are provided by the FISCO model.
