Example of connection designation for an output:

(2) Q 2.6

Output 6 (6th bit); 0 to 7 possible

Address of output byte (2nd byte);

0 to 255 possible

Q = Output

2nd terminal L+ (not specified in the ad- dress)

g	=	Green LED (status indicator)
r	= Red LED (short-circuit indicator)
F+	=	Enable input, referred to 0 V ground

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. 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.
