Explanation
Failure in the 3rd external fan or the cor-
responding tacho signal. The power is not
reduced. This is done by way of tempera-
ture curtailment. All 3 LEDs light up on
the device.
The measurement or actuation of the
semiconductors failed. If applicable, the
integrated AC filter can no longer be dis-
charged below 50 V.
Semiconductor module x in channel A is
defective or the corresponding filter relay
does not close correctly.
See explanation in Status 189
See explanation in Status 189
Semiconductor module x in channel B is
defective or the corresponding filter relay
does not close correctly.
See explanation in Status 191
See explanation in Status 191
The DESAT of the IGBTs has tripped or the
power supply (24 V) of the gate drivers is
too low.
Protective shutdown due to an exces-
sively high grid voltage. It is the effective
value which is decisive for the shutdown
procedure.
See explanation in Status 203
See explanation in Status 203
AC overvoltage trip-off that was triggered
by a hardware comparator.
The data saved on the control card is er-
roneous.
Remedy
Is the fan jammed? For trained electri-
cians: Are plugs connected correctly?
Make sure there is no grounding prob-
lem.
Disconnect the device on the AC and DC
side.
Observe the wait time on the warning
sign.
Switch the device on again. If this mes-
sage is displayed again, contact Service.
Restart of the device attempted? (Discon-
nect AC/DC - switch it back on after 5
minutes.)
=> If unsuccessful, contact Service.

Restart of the device attempted? (Discon-
nect AC/DC - switch it back on after 5
minutes.)
=> If unsuccessful, contact Service.

See remedy in Status 191
If this occurs repeatedly, contact Service. -
Is the error displayed frequently?
=>Check the installation again. Other-
wise, contact Service.
Note: Error can be caused by a poor loca-
tion on the AC side. Check all connection
terminals from the inverter through to
the grid connection. A fluctuating or miss-
ing AC voltage can indicate this connec-
tion problem.
