The combination of all output power (5V backplane, 24V backplane, and 24V user source) cannot exceed 70 W.
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.
Use time-delay type overcurrent protection in all ungrounded conductors.
Isolation is between input terminals and backplane.
CPU hold-up time is for 0V unless specified. Hold-up time is dependent on power supply loading.
