Preventive Maintenance

Toshiba's 1600 Plus 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.
