g = Green LED (status indicator)
F+ = Enable input
Connect L- of the power supply unit to the reference potential (PE).
1) Changeover of enable mode with jumper X20:
Jumper inserted = Enable input active (factory setting)
Jumper open = Enable input inactive.
2) The terminal is not connected internally. Even when this terminal is connected to input voltages, the clearances in air
and leakage paths remain adequate to UL, CSA and VDE.
