EM TEST
3.4.1.3. Phase indicator
The phase indication shows the correct connection of the supply to Phase and Neutral input of the compact
NX5. For the generator hardware both, L and N paths are potential free and a reverse connection is not relevant
for the generator operation.
For EUT where it is important that phase and neutral are correct, the LED indication shows the correct phase
connection.
