Connection diagram
In devices with protection type
ATEX II 2G Ex dem [ia/ib] T6..T3, intrinsically safe circuits must
be separated from non-intrinsically safe circuits by certified safety isolators or barriers.
For reliable communication via HART-protocol at least one load of 230 Ω must be available in
the signal circuit.
The FUS060 enclosure must be connected with an earth wire to the PE connector - see note
in figure above.
Warning
• Ex-version: According to the "Ex-requirements", the 'PE-terminals' on FUS060 and on sensors
(SONO3200 transducers or SONO 3300 sensor) must be potential equalised (min. 4 mm
2
).
•
The PE-terminals should always be connected to solve EMC problems (Ex-Version on non Ex).
• If device is energized (power supply, digital outputs in the case of external feeding), housing
covers may not be unscrewed in areas where there is a risk of explosion.
• Lid over terminals for power supply may not be removed! Use only certified measuring
instruments!
