NOTES:
1. The Fluke 707Ex Calibrator must not be used in Division 1 Hazardous (Classified) Locations.
NOTE
The Fluke 707Ex Calibrator cannot be installed using standard NEC Division 2 wiring
practices. Note 2 must be adhered to.
2. The Fluke 707Ex Ca
librator can only be used Division 2 Hazardous (Classified) Location provide
the following conditions are satisfied.
a.
The area is free of Flammable Vapors OR
b.
The connections are to a device(s) with nonincendive field wiring parameters (see notes
5 & 6) OR
c.
The connections are to a device(s) with Intrinsic Safety (see notes 4 & 6)
.
3.
Connections to an Intrinsically safe Apparatus/Associated Apparatus/Loop
must meet the requirements of notes 4, 6, & 7
Connections to an Nonincendive wiring Apparatus/Associated Apparatus/Loop
must meet the requirements of notes 5, 6, & 7
4. Intrinsic Safety Entity concept:
The Intrinsic Safety Entity concept allows the interconnection of devices with entity parameters:
Uo or Voc or Vt ≤ Vmax or Ui. Io or Isc or It ≤ Imax or Ii.
Ca or Co ≥ Ci + Ccable. La or Lo ≥ Li + Lcable. Po ≤ Pi.
Uo or Voc or Vt of Associated Apparatus ≤ Ui of Fluke 707 Ex Calibrator.
Uo (Voc) of Fluke 707 Ex mA Calibrator ≤ Vmax or Ui of Intrinsically Safe Apparatus and
≤ Uo or Voc or Vt of Associated Apparatus
Io (Isc) of Associated Apparatus ≤ Ii of Fluke 707Ex
Notes for Fluke 707Ex connected to Associated Apparatus
Vt(loop) = Vo(707Ex) + Voc or Vt of Associated Apparatus.
It(loop) = Io(707Ex) + Isc or It of Associated A
pparatus.
Pt(loop) = Po(707Ex) + Po of Associated Apparatus
Vt(loop) ≤ Ui of Intrinsically Safe Apparatus.
It(loop) ≤ Ii of Intrinsically Safe Apparatus.
Pt(loop) ≤ Pi of Intrinsically Safe Apparatus.
Uo (Voc) of Fluke 707 Ex Calibrator ≤ Vmax or Ui of Intrinsically Safe Apparatus.
Ct(loop) = Co(707Ex) + Co of Associated Apparatus + Ci of Intrinsically Safe Apparatus + Ccable
Lt(loop) = Lo(707Ex) + Lo of Associated Apparatus + Li of Intrinsically Safe Apparatus + Lcable
It(loop) ≤ Itable for calculated Vt(loop)
Ct(loop) ≤ Ctable for calculated Vt(loop)
Lt(loop)
≤
Ltable for calculated It(loop) calculated Vt(loop)
5. Nonincendive wiring concept:
The Nonincendive wiring concept allows the interconnection of devices with
Nonincendive wiring parameters:
Voc or Vt ≤ Vmax
Ca or Co ≥ Ci + Ccable
La or Lo ≥ Li + Lcable.
Voc or Vt of Associated Nonincendive Field Wiring Apparatus
≤ Vmax of Fluke 707 Ex Calibrator.
Voc of Fluke 707 Ex Calibrator ≤ Vmax of Nonincendive Field Wiring Apparatus
and ≤ Voc or Vt of associated nonincendive field wiring Apparatus
Notes for Fluke 707Ex connected to associated nonincendive field wiring Apparatus (NI)
Vt(loop) = Voc(707Ex) + Voc or Vt of Associated Nonincendive Field Wiring Apparatus.
It(loop) = Isc (707Ex) + Isc or It of Associated Nonincendive Field Wiring Apparatus.
Vt(loop) ≤ Vmax of Nonincendive Field Wiring Apparatus.
Voc of Fluke 707 Ex Calibrator ≤ Vmax of Nonincendive Field Wiring Apparatus.
Ct(loop) = Ca(707Ex) + Ca of Associated Nonincendive Field Wiring Apparatus
+ Ci of Nonincendive Field Wiring Apparatus + Ccable
Lt(loop) = La(707Ex) + La of Associated Nonincendive Field Wiring Apparatus
+ Li of Nonincendive Field Wiring Apparatus + Lcable
It(loop) ≤ Itable for calculated Vt(loop)
Ct(loop) ≤ Ctable for calculated Vt(loop)
Lt(loop) ≤ Ltable for calculated It(loop) calculated Vt(loop)
6. Installation must be in accordance with Article 500 of the NEC® (ANSI/NFPA 70)
and ANSI/ISA RP12.6
7. The Fluke 707Ex Calibrator may only be connected to loop terminals and must not be connected to
internal circuitry of Associated Apparatus or Intrinsically Safe Apparatus. Connection to internal
circuitry of Associated Apparatus or internal circuitry of Intrinsically Safe Apparatus violates Approval.
8. Applying more than 28 volts to the input terminals invalidates the Calibrator’s Ex- Approval and results
in permanent damage to the unit so it can no longer be used.
9. Refer to the 707Ex Users Manual (provided on the CD) for additional Safety Information
10.
