Fan Replacement
Under normal conditions, the original fan installation will last several years. However,
the internal fan assembly is replaceable.
CAUTION: The fan circuitry is not isolated from AC mains. Turn off
power to the UPS prior to fan replacement. Fan replacement must be
performed by qualified electrical service personnel.
ATTENTION: Before removing the fan assembly, note the fan
orientation. For proper installation and connectivity, the replacement
fan must remain in its original orientation.
