1. Read fi rst 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 SINEAX G 537 converts the phase angle diffe-
rence of two synchronised supplies into a load independent
DC current or a load independent DC voltage proportional
to the measured value.
