*1: Dust-tight conduit seal must be used when
installed in Class II and Class III environments.
*2: Installation should be in accordance with the
National Electrical Code® (ANSI/NFPA 70)
Sections 504 and 505.
*3: The configuration of Associated Nonincendive
Field Wiring Apparatus must be FM Approved.
*4: Associated Nonincendive Field Wiring
Apparatus manufacturer’s installation
drawing must be followed when installing this
equipment.
*5: No revision to drawing without prior FM
Approvals.
*6: Terminator and supply unit must be FM
Approved.
*7: If use ordinary wirings, the general purpose
equipment must have nonincendive field wiring
terminal approved by FM Approvals.
*8: The nonincendive field wiring circuit concept
allows interconection of nonincendive field
wiring apparatus with associated nonincendive
field wiring apparatus, using any of the wiring
methods permitted for unclassified locations.
*9: Installation requirements;
Vmax ≥ Voc or Vt
Imax = see note 10.
Ca ≥ Ci + Ccable
La ≥ Li + Lcable
*10: For this current controlled circuit, the parameter
(Imax) is not required and need not be aligned
with parameter (Isc or It) of the barrier or
associated nonincendive field wiring apparatus.
Electrical Data:
Maximum Input Voltage Vmax: 32 V
Maximum Internal Capacitance Ci: 1.76 nF
Maximum Internal Inductance Li: 0 µH
