KROHNE -
• The Ex [nL] electrode circuit of the OPTIFLUX x300 C (compact flowmeter) is a internal circuit.
Hence no U;, I;, P; etc parameters are applicable for this circuit.
• Connections to mains (L, N or L+, L-), signal 1/0 (A, A-, A+, B, B-, C, C-, D and D-) and field
current(7, 8, 9)can only be made when the flowmeter is not energized or when there is no
explosive gas atmosphere surrounding the flowmeter.
• Used cable glands must have an IP degree to EN 60529 of at least IP65. The glands must be
suitable for the types of cables used. For example the sealing ring must be suitable for the outer
diameter of the cables.
• The temperature class T4 or T3 of OPTIFLUX x300 C and OPTIFLUX x000 F, depends on
ambient temperature Ta and maximum process temperature Tp, according to following table:
maximum Tp in °C Ta < 40 °C 40 <_ L< 50 °C 50 <_ Ta < 60 °C
T4 130 130 60
T3 140 -- --
1.3 Serviceable parts
With exception of the mains fuse link, the IFC 300 electronic unit contains no serviceable parts. In case of
replacement of the main fuse link, 5x20 mm fuse links to standard IEC 60 127-2, breaking capacity High,
rated voltage 250 V, must be used:
Mains Mains fuse link
100...230 VAC 0,8 A Time-lag (T800H250V)
12...24 VDC 2,0 A Time-lag (T2H250V)
24 VAC/DC 2,0 Time-lag (T2H250V)
