Connection of the FLOWSIC600 with associated equipment
The terminal compartment of the FLOWSIC600 complies with the requirements of EN/
IEC60079-7 and
EN/IEC 60079-11, respectively.
The FLOWSIC600 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 connection 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.
3
Power supply connection as non-intrinsically safe wiring and all other filed connection
as intrinsically safe wiring.
A combination of intrinsically safe and non-intrinsically safe wiring for the field connections
is not permitted.
Maximum voltage in the safe area must not exceed 253 V (Um = 253V).
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/IEC60079-14
section 12.
– The safety-relevant parameters of interconnected equipment must comply with the
following values: Uo < Ui, Io < Ii, Po < Pi, Ci + Ccable < Co, Li + Lcable < Lo
The interconnection of two or more intrinsically safe outputs may require an additional
assessment of intrinsic safety in accordance with EN /IEC60079-11.
Ensure that the cover on the power supply connection is properly sealed for regular
operation.
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.
●
Wait 10 minutes after power has been removed before opening the window
cover.
●
Do not open the cover of the terminal compartment while energized unless
wiring is intrinsically safe.
●
Do not remove the cover of the power supply 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).
