9.1 Operation
The UPS system contains no user-serviceable parts. If the battery service life
(3~5 years at 25°C ambient temperature) has been exceeded, the batteries
must be replaced. In this case please contact your dealer.
9.2 Storage
If the batteries are stored in temperate climatic zones, they should be charged
every three months for 1~2 hours. You should shorten the charging intervals to
two months at locations subject to high temperatures.

Battery replacement should be performed only by qualified personnel.
It recommends to shut off the UPS completely before the replacement. If there
is a battery breaker then turn it off first. Disconnect the battery cable carefully
and make sure no any exposed wires can be touched. Reconnect the new
batteries to the UPS by following section 5.8. Then turn on the battery breaker
and start the UPS.
If it needs to replace the batteries while the UPS is running, make sure the
UPS would not shut down during the replacement. If there is a battery breaker
