CAUTION
！
・
Internal maintenance and inspection should be performed only by technically
qualified personnel. Electric shock, injury, burning, fuming or fire could
otherwise result.
・
Before beginning inspection, shut down the UPS completely, and remove the
input power. Failure to do so may result in an electric shock.
・
While the batteries are connected to the equipment, hazardous voltage is
present. Never touch any parts with your hand. Doing so may result in an
electric shock.
(1)
Inspection of external appearance and internal visual check
Inspect the components on the circuit boards for signs of overheating or corrosion. This
inspection is especially important if the equipment is installed in an environment
subject to corrosive gases or high humidity.
(2) Dust or dirt adhering to parts inside the UPS may cause it to malfunction. Remove any
dust or dirt adhering to the intake and exhaust vents and fan.
The projected service life of the UPS is about 7 years. If you intend to continue using the
UPS after its projected service life, contact your supplier regarding purchase of
components that must be replaced. If the components are not replaced at the end of the
service life, the UPS will not function properly.
(1) Battery Once every 4.5 years
See §11.4 “Battery Maintenance” for more information about exchanging the battery.
Note
・
The projected service life of the components is based on use in an ambient temperature of 25°C
(77°F). Higher temperatures result in shorter service life.
・
Parts replacement should not be attempted by customers: contact your supplier or Sanyo Denki
representative when replacement is needed.
