(1) The combination of all output power (5V backplane, 24V backplane, and 24V user source) cannot exceed 70 W.
(2) Power supply fuse is intended to guard against fire hazard due to short-circuit conditions. This fuse may not protect the
supply from miswiring or excessive transient in the power line.
(3) Fuse sizes specified are for end-devices only. Fuse size may need to be reduced depending on the size of circuit wiring.
(4) Equivalent fuses: 250V-3A fuse, nagasawa ULCS-61ML-3, or BUSSMAN AGC 3.
(5) Equivalent fuse: 250V-3A fuse, SANO SOC SD4, or BUSSMAN AGC 3.
(6) Equivalent fuse: 125V-5A fuse, LITTLEFUSE 233.
(7) Use time-delay type overcurrent protection in all ungrounded conductors.
(8) Isolation is between input terminals and backplane.
(9) CPU hold-up time is for 0V unless specified. Hold-up time is dependent on power supply loading.
