-
before connecting the power supply, verify that the mains voltage falls
between the limits indicated on the tag plate
- ATTENTION: the converters on dc power supply line (LLV version: 10-35
Vdc) they not protected against the inversions of polarity.
- For the wiring use only approved conductors, with fire-proof properties.
- The power supply line must be equipped with a external protection for
current overload (fuse or automatic line breaker with limiting capacity not
greater than 10 A).
- Provide in the proximity of the instrument a circuit breaker that must be
easily accessible from the operator and clearly identified.
- from the operator, and clearly identified.
