4. The PV system's output is too low when: the green LED does not flash and no message that the
secure power supply operation mode is enabled appears on the display or the control lamp of
the outlet does not glow. Irradiation on the PV system is probably too low or the connected
load requires more power than currently available. Carry out the following measures:
• Ensure that the outlet's switch is set to secure power supply operation.
• If irradiation is too low, wait for it to increase.
• Connect a load with lower power consumption to the outlet.
5. If no voltage can be measured at the outlet, ensure that the switch of the outlet is set to secure
power supply operation, and that the switch, outlet and control light for secure power supply
operation are correctly connected.
