7.1 Recommended Maintenance
Toshiba International Corporation recommends the UPS have regular preventative maintenance (PM) visits to ensure
optimum operation and longevity. Toshiba recommends two Major PM's per year, at six month intervals.
A Major PM includes maintenance of the batteries and an offline inspection of the UPS. Contact Toshiba International
Corporation Service Department at 1-877-867-8773 for further details.
7.2 Battery
VRLA battery lifetime may vary according to the frequency of use and the average ambient operating temperature.
The end of battery life is defined as the state of charge resulting in an ampere-hour capacity less than, or equal to,
80% of nominal capacity.
Battery replacement is recommended if its capacity is at or below this percentage.
7.3 UPS Component Parts
UPS components have a defined life expectancy (Fans, Capacitors, Filters, etc.) Life expectancies shown are based
on normal operating conditions. Life Expectancy will shorten in more extreme operating conditions.
Contact Toshiba International Corporation for a complete parts replacement schedule. Recommended replacement
time interval varies with operating environment.
