NOTE: Cutting Ground Fault jumper JP1 voids UL/NFPA Style/Class identifications for circuits
unless Ground Faults are being monitored by an FACP connected to the power supply. Cut
jumper JP1 only if a panel connected to the power supply is monitoring for Ground Faults or with
the approval of AHJ (Authority Having Jurisdiction).
