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 DW5-xxxx converts to active power of a
three-phase system with balanced or unbalanced loads.
The output signal is proportional to the measured value of the
active power and is either a load independent DC current
or a load independent DC voltage.
