Connection of the FLOWSIC30 with associated equipment
The terminal compartment of the FLOWSIC30 complies with the requirements of
EN/IEC 60079-7 and IEC 60079-11.
The FLOWSIC30 provides non-intrinsically safe wiring as well as intrinsically safe wiring
with the interconnected associated equipment in the following manner:
1 Power supply connection and all other field connections as non-intrinsically safe wiring
2 Power supply connection and all other field connections as intrinsically safe wiring to Exi
certified equipment in a Zone 1 or Zone 2 classified hazardous area or to [Exi] certified
associated equipment in the safe area.
A combination of intrinsically safe and non-intrinsically safe wiring is not permitted.
Before start-up the chosen type of installation has to be checked in the appropriate boxes
on the type label.
All the time, operating is only permitted as marked on the type plate. Non-compliance may
impair intrinsic safety. Safe area voltage must not exceed the max. voltage as indicated on
the terminal assignment label in the rear cover of the SPU (
→ Fig. 19
).
The use of SELV-/PELV power supply units or safety power converters acc. IEC 61558-2-6,
IEC 60950 or IEC 61010-1 is mandatory, if the maximum safe area voltage U
m
< 253 V.
For intrinsically safe wiring:
– The safety-relevant data in the EC Type Examination Certificate and the IECEx Certificate
of Conformity must be observed.
– Intrinsic safety for each circuit must be assessed in accordance with EN/IEC 60079-14
section 16.
– The safety-relevant parameters of interconnected equipment must comply with the
following values: U

The interconnection of two or more intrinsically safe outputs may require an additional
assessment of intrinsic safety in accordance with EN /IEC 60079-11.
For intrinsically safe wiring, the rear cover can be removed and connecting and disconnect -
ing is permitted while the circuits are live and as long as the safe separation between the
circuits has been kept.
WARNING: Explosion hazard
● Do not open the enclosure while energized.
● The window cover must not be opened while an explosive atmosphere is
present.
● Do not open the cover of the terminal compartment while energized unless
wiring is intrinsically safe.
● Do not connect or disconnect while circuits are live unless the area is
known to be non-hazardous or wiring is intrinsically safe.
● Do not use the equipment if damaged (includes cables or terminals).
