8.3 Parts Replacement
The following list shows intervals for periodic maintenance and replacement of certain UPS parts.
1) Batteries: VRLA (Valve Regulated Lead Acid) batteries do not require the adding of water or electrolyte. The charging voltage, temperature, performance and connection resistance must be monitored periodically. Necessary corrective maintenance must be made in order to assure the UPS supplies safe reliable power. These 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 to eliminate the possibility of multiple failures due to resistances of the batteries.
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 individual unit’s float charging voltage.
Recommended Semi-Annual maintenance
A. Repeat the quarterly checks.
B. Perform impedance checks on the individual batteries.
C. Optionally test for the purpose of trending the battery over time.
D. Re-torque all inter-battery connecting hardware (if applicable).
2) Aluminum electrolytic capacitors: Replace once every 5 years.
3) Fuses: Replace once every 7 years.
4) Cooling fan: Replace once every 3 years.
