Possible causes
- The automatic phase
and null fuses from the
general supply panel are
not connected.
- The power supply cable
from the 230V AC
network is broken.
Short-circuit at the L1-L2
terminals of the Terminal
or L1-L2 terminals of the
Outdoor Panel, or both
terminals of the Power
supply.
The connection cable
between the Terminal
and the Power supply is
broken or the wires are
not well fastened in the
connectors, either at the
Power supply, or at the
Terminal.
The connection cable of
the Outdoor panel to the
Power supply is broken
or the wires are not well
fastened in the
connectors, either on the
Power supply, or at the
Outdoor panel.
The connection cable of
the Terminal to the Power
supply was incorrectly
connected to L1-L2
Outdoor Panel and the
connection cable of the
Outdoor panel was
connected to the L1-L2
Terminal.
±
Solutions
Connect the phase and null
fuses.
Verify the integrity of the
power supply cable.
Eliminate the short-circuit;
the LED of the Power
supply must be
permanently GREEN.
Check if the wires are well
fastened in the connectors
both at the Power supply,
and at the Terminal.
Check the integrity of the
connection cable with an
Ohmmeter; replace the
broken cable.
Check if the wires are well

and at the Outdoor panel.
Check the integrity of the
connection cable with an

broken cable.
The outdoor panel and
terminal connection cables
are correctly connected to
the Power supply: the
Outdoor panel is connected
at L1-L2 Outdoor Panel and
the Terminal at L1-L2
Terminal.
