4 MAINTENANCE AND BATTERY REPLACEMENT
4.1 Precautions
Although the PSA5 is designed and manufactured to ensure personal safety, improper use can result in
electrical shock or fire. To ensure safety, observe the following precautions:
•
Turn off and unplug the UPS before cleaning it.
•
Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.
•
Never block or insert any objects into the ventilation holes or other openings of the UPS.
•
Do not place the UPS power cord where it might be damaged.
4.2 Battery Charging
The batteries are valve-regulated, non-spill-able, lead acid and should be kept charged to attain their
design life. The PSA5 charges the batteries continuously when it is connected to the utility input power. If
the PSA5 will be stored for a long time, we recommend connecting the UPS to input power for at least
24 hours every 4 to 6 months to ensure full recharge of the batteries.
