Preventive and Scheduled Maintenance/Parts Replacement
8.1
Preventive Maintenance
Toshiba's 1400SE 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 from the system. Schedule authorized service
centers to perform internal parts inspections annually.

Parts Replacement
The following list shows intervals for periodic maintenance and replacement of certain
UPS parts.
1)
Batteries: VRLA batteries are maintenance free with respect to electrolyte only.
The charging voltage, temperature, performance and connection resistance must
be monitored periodically. Necessary corrective actions must be made in order to
assure safe reliable power is supplied by the UPS. The aforementioned items
affect the life of batteries, so replacement should be once every 3 to 5 years as a
minimum. All of the batteries must be replaced at the same time.
Quarterly maintenance
a) Visual checks
b) Check battery temperature at the negative terminal.
c) Measure and record the system float charging voltage.
d) Measure and record the individual units float charging voltage.
Semi-Annual maintenance
a) Repeat the quarterly checks.
b) Perform a 10 second high rate (e.g. 100 amp) load test on the
c) Optionally test for the purpose of trending the battery over time.
d) Re-torque all inter-battery connecting hardware (if applicable).
e) Perform inter-battery connector resistance checks.
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.
