Preparation

Checking winding connections

With an open winding design, i.e. when the windings start and end directly at the terminal box
(see the "Terminal marking" (Page 66) section), the connections are made using jumpers in
the terminal box. The jumpers for the open connection must not be removed when testing the
winding; refer to the relevant circuit diagram.
● Check that the connections (star or delta) comply with the specifications on the rating
● Ensure that the connection values correspond to the information on the rating plate.
