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.
Example of connection designation for an
input:
(1) I 1.5
Input 5 (5th bit);
0 to 7 possible
Address of input byte
(1st byte);
0 to 255 possible
I = Input
