Flowire Converter Configuration Manual

System Configuration with Industrial & Ex Devices
The Ex device (TFIX station, EAPFX access panel) located in a hazardous zone is connected to the
central equipment rack located in the safe zone using an Ex certified 2-wire shielded cable. FCDC2
is used to extend the Ethernet connection and support power distribution on the 2-wire cabling
infrastructure.
Each industrial device (TFIE station, EAPII access panel) located in an outdoor area will require its
own FCDC1 Flowire Converter.
To support the Flowire interface, the central equipment rack must be equipped with an FCDC2
Flowire Converter.

Ex devices such as the TFIX station and EAPFX access panel MUST use 24VDC power
supply for the FCDC2. The devices will be damaged if 48VDC power supply is used.
L
Do NOT use FCDC1 in the central equipment rack as this may damage the Ex devices.
