Preventive and Scheduled Maintenance / Part Replacement

8.1

Preventive Maintenance

Toshiba's 1600XPi Series of UPS battery cabinets have been designed to provide years of trouble-free
operation requiring a minimum of preventive maintenance.
The best preventive measure that the battery cabinet 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 from the air
inlet vents. Schedule authorized service centers to perform internal parts inspections annually.
