P URPOSE The purpose of this test was to apply a postulated design basis electrical

' fault to the input and output of the isolator module.

The faul t wa s applied in the transverse mode.

The characteristics of the fault are as follows:

(1) 120 VAC to the input of the module and (2) 120 VAC to the output of the module.

A hi-pot test was conducted at the conclusion of the fault testing to verify that no isolation breakdown had occurred.
