Note: AL1024ULX series power supply is designed to work with batteries up to 65AH. Please note, line [I]
must not exceeds 36AH. You have to reduce either standby current consumption or standby time in order to
comply with requirement.
To determine actual battery size please round line [J] to the nearest larger standard battery size
(e.g. 3.5 AH = 4.0 AH).
