Preventive Maintenance/Parts Replacement
Preventive Maintenance
Toshiba 1600XP Series of uninterruptible power systems have been designed to provide years of trouble-
free operation requiring a minimum 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.
CAUTION
Only a qualied 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.
Cleaning the Touchscreen
The touchscreen display is covered with a protective Teon coating. It should be cleaned with a clean,
damp cotton cloth to avoid scratching the coating.
