1. Read first and then …
The proper and safe operation of the device
assumes that the Operating Instructions is
read carefully
and the safety warnings given
in the various Sections
4. Mounting
5. Electrical connections
are
observed
.
The device should only be handled by appropriately
trained personnel who are familiar with it and authorised
to work in electrical installations.
2. Brief description
The transducer SINEAX U 539 is designed to convert a
sinusoidal AC voltage into a DC current or voltage proportio-
nal to the measured value.
