NOTE
If a residual current circuit breaker is necessary due to the installation specification, a type A residual current
circuit breaker must be used.
For questions regarding the appropriate type, please contact the installer or the system manufacturer's service
department.
NOTE
When the line resistance is high, i.e. long cables on the grid side, the voltage drop on the line increases, and the
terminal voltage is higher or lower than the country-specific limit value, the device shuts down.
1. Ensure that the cable cross-sections are sufficiently large or that the cable lengths are sufficiently short.

Connecting the battery to the device
DANGER
Risk of fatal injury due to electric shock!
When connecting the batteries and installing supply lines, arcs may occur that may cause serious injury and
property damage.
1. Insert internal fuse before connecting the DC voltage.
2. Repair damage to the DC line without delay.
3. Batteries must be fitted with potential equalisation in protection class I and with double-insulated DC cable
in protection class II.
CAUTION
Danger caused by reverse polarity at the DC connection.
The device does not have reverse polarity protection on the DC connection. This can lead to destruction of the device.
1. Check polarity using suitable measuring equipment before connecting the DC cable.
2. Failure to observe these warnings may lead to device damage which is not covered by the manufacturer warranty.
