Routine Maintenance

5.1 UPS Maintenance

NO TICE

● Only trained personnel are allowed to perform maintenance tasks. Before

performing operations on the UPS, wear electrostatic discharge (ESD) clothes,

ESD gloves, and an ESD wrist strap. Remove conductive objects such as jewelry

or watches during operations to avoid electric shocks or burns.

● Use insulated tools when maintaining internal devices. Only trained personnel

are allowed to perform maintenance. Customers are not allowed to maintain

components behind protective covers that can be removed only using tools. If

the components are to be maintained, contact technical support.

● Only maintenance engineers are allowed to maintain power modules and

bypass modules.

● Maintain UPSs regularly based on the following requirements. Otherwise, the

UPSs may fail to operate properly and the service life may be shortened.
