An electric shock can be fatal. The housing may only be opened by ser-
vice technicians trained by the manufacturer. Before working with the
housing open, the device must be disconnected from the grid. A suit-
able measuring device must be used to ensure that electrically
charged parts (e.g. capacitors) are completely discharged. Ensure that
the device remains disconnected from the grid until all work is com-
plete.
Use functions only after reading the Operating Instructions in full.
Keep potential sources of ignition such as fire, sparks, and open flames
away from the battery.
Danger of explosion! Oxyhydrogen forms in the battery during char-
ging.
Battery acid is corrosive and must never come into contact with your
eyes, skin or clothing.
Ensure there is a sufficient supply of fresh air during charging.
The device can cause DC residual currents in the ground conductor. If
a residual current device (RCD) is used on the grid side to protect
against electric shock, this must be a type B RCD. The device has an
increased leakage current. This must be taken into account when in-
stalling the device in accordance with national regulations.
Do not dispose of the product with household waste, but in accordance
with the disposal regulations for waste electrical and electronic equip-
ment applicable at the place of installation.
