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.
