(1) 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.
(2) Isolation is between input terminals and backplane.
(3) CPU hold-up time is for 0V unless specified. Hold-up time is dependent on power supply loading.
(4) See the Product Certification link at http://ab.com for Declarations of Conformity, Certificates, and other certification details.
(5) See page 70 for information on power supply under voltage operation.
