8.2 Replacing batteries
Lead-acid AGM batteries contain hazardous, poisonous substances.
When handling the batteries, and during transport and disposal,
local regulations must be adhered to.
Warning!
Batteries are subject to the risk of an excessively high short-circuit
current. To prevent this, do not connect anything between the bat-
tery contacts and other conductive parts.
The batteries must only be replaced with the original battery set (order no.
00 0648 85). Other batteries may result in problems because of their connections
and dimensions.
Risk of electric shock!
Before opening the housing of the power supply unit UPS, you must
disconnect it from the power. Failure to observe this may result in
persons touching live parts or experiencing serious injury.
