Preventive Maintenance
Toshiba's 1600EP 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.
Only a qualified 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.
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 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:
