*1: Dust-tight conduit seal must be used when installed
in Class II and Class III environments.
*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 RP12/6 “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 Research Approved under FISCO
Concept.
*5: Associated Apparatus manufacturer’s installation
drawing must be followed when installing this
equipment.
*6: The EJA100 Series are approved for Class I, Zone
0, applications. If connecting AEx (ib) associated
Apparatus or AEx ib I.S. Apparatus to the Zone 2,
and is not suitable for Class I, Zone 0 or Class I,
Division 1, Hazardous (Classified) Locations.
*7: No revision to drawing without prior Factory
Mutual Research Approval.

Note: In the rating 1, the output current of the barrier must be
limited by a resistor “Ra” such that Io=Uo/Ra. In the rating
2 or 3, the output characteristics of the barrier must be the
type of trapezoid which are certified as the FISCO model
(See “FISCO Rules”). The safety barrier may include a
terminator. More than one field instruments may be
connected to the power supply line.
