8.0 Preventive Maintenance/Parts Replacement
8.1 Preventive Maintenance
Toshiba's 1400XL Plus 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.
Before performing any maintenance, the certified repair
technician must be familiar with and follow the important
safety instructions located on pages v and vi.
8.2 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 on a regular schedule. To ensure reliable operation, all
of the batteries should be replaced at the same time. Use the following
chart for replacement:
2) Aluminum electrolytic capacitors: Replace once every 5 years.
3) Fuses: Replace once every 7 years.
