When should I consider buying the “XM” Option over the standard HG7 filter?

The HG7 standard product is a high performance filter that will perform the function of mitigating excessive harmonics related to the drive system. The “XM” Option goes beyond that to allow additional control, alarm, and monitor features. The “XM” Option would be the desired version to specify if the customer is looking for alarm features should a filter fault occur or be able to turn off the filter circuit without shutting down the drive.
