C. DC-ok LED (green)
Indicates a normal operation. The LED is on
if the output voltage is higher than 43.2V.
D. Warning LED (yellow)
- A steady-state light indicates an output
current higher than the nominal current
and that the internal shutdown timer is
running.
- A double flash indicates a phase-loss or
too low / too high input voltage.
(< 3x400Vac or > 3x560Vac)
- A fast flash warns of an impending
temperature shut-down. A shut-down
can be expected within 10 minutes, if
the ambient temperature or the load
current stays constant.
E. Shut-down LED (red) and reset button F.
The red LED flashes when the device has
shut down. Pressing the reset button or
cycling the input power (10s required)
initiates a restart. When the fault is
cleared, the device will operate normally.
