11.1 Daily Inspection

Check the control panel LED indicators to confirm that no error is indicated. No other special inspection or maintenance is required.

11.2 Periodic InspectionInspect the following items once every 6 months.

qualified personnel. Electric shock, injury, burning, fuming or fire could

 

otherwise result.

 

・ Before beginning inspection, shut down the UPS completely, and remove the

CAUTION

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.

11.3Parts Replacement

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.
