Risk of injury!

Do not place anything between the inverter terminal and the ring cable lug.
Otherwise, this can lead to overheating.

Do not apply an antioxident to the terminals before the terminals are securely
connected.

Before establishing the final DC connection or closing the DC power switch/
circuit breaker, ensure that plus (+) is connected to plus (+) and minus (-) is
connected to minus (-).

For safe operation and the observance of regulations, it is necessary, to install a
separate DC overcurrent protection or an isolating device between the battery and
the inverter. In many applications, an isolating device may not be necessary.
Nevertheless, the installation of an overcurrent protection is still required. Please
refer to the typical current in the following table for the required fuse size or the
