The inverter connection compartment must only be opened by an autho-
rised installation engineer.
Never open the connection compartment when the power is connected.
The separate power module housing must only be opened by a trained
Fronius service technician and only when in a de-energised state.
The design and operation of the inverter ensures maximum safety when
installing the Fronius Signal Card. The DC and AC sides are fully galvani-
cally (electrically) isolated from one another to ensure optimum levels of
safety.
To provide maximum safety during operation, the connections of the Fro-
nius Signal Card are also fully galvanically (electrically) isolated.
Never route leads connected to the Fronius Signal Card together with
mains leads.
Repairs to the inverter and the Fronius Signal Card may only be carried
out by a trained Fronius service technician.
