11.9.1 Pre-Test & Start-Up
Fast flashing Fast flashing Fast flashing
Duration 3 seconds before starting of
sinus generation.
11.9.2 Ready to Start Slow flashing Slow flashing Slow flashing
Inverter ready for generating the
sinus voltage.
11.9.3 Normal Operation
3
OFF ON OFF Normal operating of the inverter.
11.9.4 Overload Condition
Slow flashing ON ON
Avoid to operate in these conditions
(check the loads).
11.9.5 Overload Protection
ON OFF ON
No output voltage.
Generator must be switched OFF and
ON.
11.9.6 Overtemperature
Condition
Slow flashing- ON Slow flashing
Automatic current derating
activation.
11.9.7 Overtemperature
Protection
ON OFF Slow flashing
No output voltage. Generator must
be switched OFF and waited for its
cooling down (see 11.5.5).
11.9.8 Output Undervoltage (see
paragraph 11.5.7)
OFF Slow flashing OFF
No output voltage. When voltage
comes back to tolerance values, an
automatic restart will happen.
11.9.9 Output Undervoltage (not
Severe) Protection
ON Slow flashing ON
No output voltage. Generator must
be switched OFF and ON.
11.9.10 Output Undervoltage
(Severe) Protection

11.9.12 BUS Overvoltage
Protection
ON OFF Fast flashing
No output voltage. Generator must
be switched OFF and user must wait
for full discharge of BUS capacitors
(all LEDs must be OFF).
11.9.13 Inverter Failure

11.9.14 Brake Resistor Protection
ON Fast flashing Fast flashing
No output voltage. Generator must
be switched OFF and user must wait
for full discharge of BUS capacitors
(all LEDs must be OFF).
11.9.15 Generator Behavior ON ON ON
Input frequency signal lost on input
line voltage L1 – L3.
AC voltage applied to the inverter
output.

When switching on, the inverter can find a voltage already present on its output terminals and consider this still as a
normal operating situation if this voltage stays into the specification. In such case the inverter will try to put itself in
parallel with this source.
