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.
Unauthorized repair or alteration of the unit invalidates
the warranty.
2. Brief description
The DCT-xxx transducer is designed to convert a sinus oidal
AC current into a DC current or voltage proportional to the
measured value.
