Preventive Maintenance/Parts Replacement

7.1

Preventive Maintenance

Toshiba's 1400 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 from the system.

Parts Replacement

The following list shows recommended intervals for periodic replacement of certain
UPS parts.
1) Batteries: In order to maintain system reliability, the UPS unit's batteries
should be replaced once every 3 to 5 years. To ensure reliable operation, all
of the batteries should be replaced at the same time.
2) Aluminum electrolytic capacitors: Replace once every 5 years.
3) Fuses: Replace once every 7 years (see output fuse rating chart below).
4) Cooling fan: Replace once every 3 years.
