g = Green LED (status indicator)
r = Red LED (short-circuit indicator)
F+/F- = Enable input
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. When this terminal is connected to the output voltages, the clearances in air
and leakage paths are no longer adequate to UL and CSA, but comply with VDE.
3)
By connecting L- to pin 42, a leading and trailing connection to 0 V ground is created on the module when it is inserted
and removed.
