Isolation Tests - GE F650 Instruction Manual

10.4 ISOLATION TESTS

10.4ISOLATION TESTS
During all tests, the screw located on the rear of the relay must be grounded.
For verifying isolation, independent groups will be created, and voltage will be applied as follows:
2200 RMS volts will be applied progressively among all terminals in a group, short-circuited between them and the
case, during one second.
2200 RMS volts will be applied progressively between groups, during one second.
WARNING: No communication circuit shall be tested for isolation.
Groups to be created will depend on the type of modules included in F650, selectable according to the model.
The following table shows the different groups depending on the module type:
