Installation Notes for FISCO Concepts in FM:
1. The Intrinsic Safety FISCO concept allows the interconnection of FM Approved Intrinsically safe devices
with FISCO parameters not specifically examined in combination as a system when:
Uo or Voc or Vt
2. Control equipment connected to the Associated Apparatus must not use or generate more than 250 Vrms
or Vdc.
3. Installation should be in accordance with ANSI/ISA RP12.06.01 (except chapter 5 for FISCO
Installations) "Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations" and the
National Electrical Code® (ANSI/NFPA 70) Sections 504 and 505.
4. The configuration of associated Apparatus must be Factory Mutual Approved under the FISCO concept.
5. Associated Apparatus manufacturer's installation drawing must be followed when installing this
equipment.
6. The ND9100P / ND9100F Series Valve Controllers are Approved for Class I, Zone 0, applications. If
connecting AEx[ib] Associated Apparatus or AEx ib I.S. Apparatus to the ND9100P / ND9100F Series
Valve Controller Fieldbus System, the ND9100P / ND9100F Series Valve Controller is only suitable for
Class I, Zone 1, or Class I, Zone 2, and is not suitable for Class I, Zone 0 or Class I, Division 1,
Hazardous (Classified) Locations.". In addition, if any Associated Apparatus or I.S. device connected to
the Fieldbus System is rated for IIB only, the ND9100P / ND9100F Series Valve Controllers must only be
installed in a Group IIB environment
7. The metallic enclosure of the ND9000 valve controller must be grounded and bonded in accordance with
the National Electrical Code ANSI / NFPA 70, Article 250
8. The cover of the ND9000 enclosure may be removed in hazardous location for reading the display and
operating the push buttons. The internal cover of the electronic circuits must not be removed in
hazardous areas.
9. The shield in the field wiring cable shall be connected to the earth ground of the shunt diode / FISCO
supply barrier in the unclassified location.
10. If you agree, please revise the control drawing by adding this note.
11. The valve controllers ND9100P/U2 and ND9100F/U2 are non-incendive for Class I, Division 2, Groups
A,B,C and D; Class I, Zone 2, Groups IIC, IIB, IIA T4 / T5 / T6 hazardous (classified) locations and need
to be connected to an associated apparatus with a max. output voltage of 24,0V.
12. No revision to drawing without prior Factory Mutual Approval.
