17. Preventive Maintenance/Parts Replacement
17.1 Preventive Maintenance
Toshiba T1000 is designed to provide years of trouble-free operation requiring a minimum amount of
preventive maintenance.
The best preventive measure that the UPS user can take is to keep the area around the unit, particularly the
air inlet vents, clean and free of moisture and dust accumulations. If the atmosphere of the installation site
is very dusty, use a vacuum cleaner to periodically remove dust accumulations around and from the unit.
Only a qualified Toshiba representative should be allowed to perform any
routine maintenance or service on this equipment other than those preventive
maintenance details which are described directly above this caution.
17.2 LCD Display Cleaning
The LCD display should be cleaned with a clean, damp cotton cloth to avoid scratching the coating.
17.3 Battery Replacement
The T1000 comes equipped with internal backup batteries packaged in three sets of 6 batteries per bat-
tery pack.
Ensure the T1000 battery packs are replaced with battery packs of the same part num-
ber. Failure to do so may cause unexpected loss of backup power.

1.
Electrolytic capacitor PC Board: Replace capacitor boards once every 5 years.
(The electrolytic aluminum capacitors are mounted on a PC Board)
