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 transducer DVT-XXXA is designed to convert a sinusoidal
AC voltage into a DC current or voltage signal proportional
to the measured value. It does not require a separate power
supply.
