(1)
Power supply fuse is to guard against fire hazard due to short-circuit conditions. Fuse may not protect the supply from miswiring or excessive transient in the power line.
(2)
Use time-delay type overcurrent protection in all ungrounded conductors.
(3)
Isolation is between input terminals and backplane.
(4)
CPU hold-up time is for 0V unless specified. Hold-up time is dependent on power supply loading.
(5)
Fuse sizes specified are for end-devices only. Fuse size may need to be reduced depending on the size of circuit wiring.
(6)
Equivalent fuses: 250V-3A fuse, nagasawa ULCS-61ML-3, or BUSSMAN AGC 3.
