7-1 Operation
The UPS system contains no user-serviceable parts. If the battery service life (3~5
years at 25
ambient temperature) has been exceeded, the batteries must be replaced.
In this case please contact your dealer.
7-2 Storage
If the batteries are stored in temperate climatic zones, they should be charged every
three months for 8-10 hours (see Chapter 5 "Connection and Operation"). You should
shorten the charging intervals to two months at locations subject to high temperatures.
