" These components are provided with RGU standard options. Not all RGUs will have these components.
➁ If your M-code RGU is equipped with a 4kHz carrier frequency control power filter (EA10), then F4 and F6 will be 17.5 KLDR (380V AC, 5kVA
transformer) or will be 15A KLDR (460V AC, 5k VA transformer). All other fuses remain the same.
