be FM approved.
9.3 The control drawing of field equipment or other equipment must be followed at the installation.
9.4 The following conditions must be met. See tables for the nonincendive field wiring parameters of
ProSafe-RS.
Vmax ≥ Voc or Vt; Imax ≥ Isc or It; Ca ≥ Ci + Ccable; La ≥ Li + Lcable
9.5 For current controlled circuits, Imax of the nonincendive field wiring apparatus is not required
and need not be aligned with parameter Isc or It of ProSafe-RS or other associated nonincendive
field wiring apparatus.
