5 CONNECTING CABLES
NOTE:
The below described cables are shown in the connection diagram on the following page.
Cable A:
Signal cable for current output and binary outputs (pulse and status output). The cable
parameters must be in accordance with the regulations in the EN 60079-14 "Electrical
installations in hazardous locations" or an equivalent national standard (e.g. DIN VDE 0165).
For the MODIS version with IFC 090i-EEx electronics unit (right detail in connection diagram)
the signal cable for the intrinsically safe signal in-/outputs must also conform the
requirements as specified in the relevant standard national code of practice for the
installation of electrical apparatus with type of protection Intrinsic Safety "i".
Cable B:

Cross-sectional area: 4 mm 2 (equivalent to AWG 10)
6 MAINTENANCE
The IFM 4080 K/…-EEx magnetic-inductive compact flowmeters are maintenance free with
regard to the flowmetering properties. Within the scope of the periodical inspections, which
are required for electrical apparatus that are installed and used in hazardous classified
locations, it is recommended to check the flameproof enclosure(s).
