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 battery
contacts and other conductive parts.
» For this reason, you should remove any watches, bracelets, rings
and other metal objects before starting work on the open interruptib-
le power supply.
» Only use tools with handles that have standard insulation.
Risk of electric shock!
Before opening the housing of the uninterruptible power supply, you
must disconnect it from the power. Failure to observe this may result
in persons touching live parts or experiencing serious injury.
