This must be connected to terminals 1 (V
via the shortest possible routing. An approximately
0.33µF 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.

Note on Thermal Protection Characteristics:
The thermal protection circuit is intended for protection
against heat during instantaneous short-circuiting. Its
operation, including reliability, is not guaranteed for
short-circuiting over an extended period of time.
