This must be connected to terminals 1 (V
via the shortest possible routing. An approximately
0.33 F capacitor with good high frequency
characteristics must be connected in parallel in case of
inductive input lines or long-distance wiring. Tantalum
capacitors are recommended for C
at low temperatures.
Required as protection against reverse biasing between
input and output.
