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-XXXX is designed to convert a sinusoidal 
AC voltage into a DC current or voltage proportional to the 
measured value.
