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.
•
Batteries should be replaced periodically.
Batteries used after their service life has passed may cause a fire.
The projected service life of the UPS is about 7 years. During this period, the battery must be replaced
periodically. If you intend to continue using the UPS after its projected service life, components other
than the battery also need to be replaced (a fee will be charged). Contact your supplier. If these
components are not replaced at the end of the service life, the UPS may not function properly.
There are routine checks to be performed by the user and maintenance to be performed by service
personnel. Some maintenance items are not able to be performed by the user, so be sure to submit a
request for such work to your supplier when maintenance is required.
Parts replacement should not be attempted by customers.
Contact your supplier or Sanyo Denki representative
when replacement is needed.
