8.0 Preventive and Scheduled Maintenance / Part Replacement
8.1 Preventive Maintenance
TOSHIBA 4200 FA 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 factory service representatives to
perform internal parts inspections semi-annually.
CAUTION
Only factory trained representatives should perform repairs or
maintenance on the UPS..
CAUTION
Proper maintenance of the battery system of this unit by a qualified
service technician is essential to the safety and reliability of your UPS
system. Refer to the battery service manual.
8.2 Parts Replacement
The following list shows intervals for periodic maintenance and replacement of certain UPS
parts.
1) Batteries: Valve Regulated Lead Acid (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.
Recommended Quarterly Maintenance
A. Visual Checks
1) Leakage.
2) Corrosion on positive terminal.
B. Check battery temperature at the negative terminal.
C. Measure and record the system float charging voltage.
D. Measure and record the float charging voltage of each unit.
Recommended Semi-Annual Maintenance
A. Repeat the quarterly checks.
B. Perform impedance checks on the individual batteries.
C. Test for the purpose of trending the battery over time.
D. Re-torque all battery connecting hardware (if applicable).
