With the Fronius Eco, the three phases
and the neutral conductor must be passed
through a ferrite ring. The ferrite ring is
supplied with the inverter.
The ground conductor (PE) must not be
passed through the ferrite ring.
The fastening screw must also be
tightened for an unassigned ground con-
ductor (PE) connection.
Note! Observe the torque values marked
on the side underneath the terminals.
If AC cables are laid over the shaft of the
DC main switch or across the connection
block of the DC main switch, they may be
damaged when the inverter is swung in or
they may even prevent the inverter from
being fully swung in.
IMPORTANT! Do not lay AC cables over
the shaft of the DC main switch or across
the connection block of the DC main
switch.
