NOTES: 1. Connections to an Intrinsically Safe Apparatus /Associated Apparatus/Loop must be in acordance with notes 2 thru 5 2. Intrinsic Safety Entity Concept: The Intrinsic Safety Entity Concept allows the interconnection of two or more Approved Intrinsically Safe devices or Associated Apparatus with entity parameters not specifically examined in combination as a system when: 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
4. The Fluke 725Ex Multi Function Calibrator may only be connected to terminals with compatible entity parameters except as indicated in Note 2 and must not be connected to internal circuitry of Associated Apparatus or Intrinsically Safe Apparatus. Failure to comply with this rule violates approval.
6. Refer to the 725Ex User Manual (provided on the CD) for additional safety information. 7.No revision to this drawing is permitted without approval from CSA and KEMA 12345
