Pair 1 Pair 2 Pair 3
Fieldbus Voltage Ui = 14 Volt DC Ui = 17.5 Volt DC Ui = 32 Volt DC
Fieldbus Current li = 570 mA li = 319 mA li = 100 mA
CAUTION
Make sure that the sum of power supply voltage and fieldbus supply voltage does not exceed
60 VDC!
Explosion hazard
Do not disconnect equipment unless power has been removed or the area is known to be
non-hazardous.
Observe relevant national regulations, standards and directives
This manual does not supersede the relevant national regulations, standards and directives.
These must be observed and have to be applied according to the national conditions!
3.1.1.2 Hazardous Location - European and International Approval (ATEX, IECEx)
The equipment has been assessed as based on the following standards and editions:
a) EN IEC 60079-0:2018
b) IEC 60079-11:2011 Ed. 6 + Corr. 2012 / EN 60079-11:2012
c) EN IEC 60079-7:2015+A1:2018
If indicated on the device label or by technical documentation, the FG-200 is suitable for use in gas-Ex
atmospheres of Zone 2 in the explosion groups IIA, IIB and IIC in temperature class T4, if accommodated in
a tested enclosure.
§
IECEx BVS 15.0055 x marking for explosion protection: Ex ec IIC T4 Gc,
Ex ec [ic] IIC T4 Gc
§
BVS 15 ATEX E 063 X marking for explosion protection: II 3G
The Ex protection method [ic] corresponds only to the FF-H1 fieldbus interfaces.
The FG-200 HSE/FF Modbus complies with the applicable standards and regulations and meets the
requirements of Directive 2014/35/EU. The requirements for erecting the device as part of the system in
potentially explosive atmospheres (e.g. IEC / EN 60079-14) must be strictly adhered.
