7. Maintenance

7.1 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.

7.2 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.
