RSD PEFS-EL Series
4 Operation
4.1 Normal operation:
The PEFS will automatically switch to the off position, breaking the DC connection between the solar panels and the inverter,
after the AC power to the PEFS is interrupted for longer than five seconds. The PEFS will automatically switch to the on position,
restoring the DC connection between the solar panels and the inverter, once the AC power to the PEFS is restored longer than
five seconds.
4.2 Special Operation:
If the temperature inside the PEFS enclosure exceeds the 70℃, the PEFS will automatically switch to OFF to protect the internal
components and create a safe situation. When the installation is checked and the PEFS is not affected, the PEFS can be
switched ON again by removal and re-applying the AC voltage to the PEFS. The PEFS will also automatically switch to OFF if
there is an internal failure. If this occurs please try to reset the PEFS by removal and re-applying the AC voltage to the PEFS.
