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.
Example of connection designation for
an output:
(1) Q 1.6
Input 6 (6th bit);
0 to 7 possible
Addressof output byte
(1st byte);
