The batteries in an uninterruptible power supply must only be replaced by electri-
cal installers who have been trained for such tasks and who have the appropriate
qualifications.
The electrical installer must have read and understood this document as well as
the operating instructions on the uninterruptible power supply and must follow its
instructions.
The electrical installer must adhere to the valid national regulations in his/her
country governing the installation, functional test, repair and maintenance of
electrical products.
The electrical installer must be familiar with and correctly apply the "five safety
rules" (DIN VDE 0105, EN 50110):

Safety instructions
Warning
» It is essential that you read the following safety instructions carefully
before you start work. The information that follows is of a general
nature. You will find specific warnings at the points in the text that
describe the potentially dangerous actions.
»
Electrical systems may only be constructed, extended, modified and maintai-
ned by an authorised group of personnel.
»
Work must only be carried out when the system has been disconnected from
the power. Before starting installation and service work, the input voltage
must be disconnected and secured to prevent it being reconnected. Failure
to observe this may result in persons touching live parts or experiencing se-
rious injury.
»
The supply voltage must be connected in accordance with the regulations
that apply in the country concerned (in Germany's case, these are VDE 0100
and VDE 0160).
»
If the values specified in the technical data are exceeded, there is the risk of
the device overheating, which may result in the supply voltage device being
destroyed and the electrical safety being impaired.
»
General safety instructions on handling batteries must be observed. In parti-
cular, it is important to ensure that sufficient ventilation is available to prevent
the build-up of explosive hydrogen and air mixtures.
