Is the 2230G-HRM Harmonic Reduction Module required in the U.S.?

No, the 2230G-HRM is not required for operation in the United States.
This product is required by new European harmonic standards for use with the 2230G series power supplies to reduce line power current harmonics.
The supply does not require this module when used in Asia or the Americas, as the standard does not apply in these regions.
