Repair of Static Trip Devices
35
Because of the complexity of the semi-conductor compo-
nents and circuits and because some of the components are
especially selected or matched, we do not recommend field
repair of static trip devices. Moreover, component failure
usually does not show up as visual damage and locating the
defective component or components requires specialized
techniques. Therefore, if the tests described in these instruc-
tions indicate that a static trip device or the test set itself is
defective, contact your nearest Siemens representative for
instructions on returning the unit to the factory or other
authorized service facility for repair
