g = Green LED (status 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) Only 128 to 255 permissible with group signal and interrupt.
3) The terminal is not connected internally. When this terminal is
connected to the input voltages, the clearances in air and
leakage paths are no longer adequate to UL and CSA,
but comply with VDE.
4) The terminal is not connected internally. When this terminal is
connected to the input voltages, the clearances in air and
leakage paths remain adequate to UL, CSA and VDE.
