FAQ-09 How do I change the device to 60 Hz mains frequency?

Requirements: the voltage L1 to N is at least 200 V AC and the device software is at least v516.

  1. Open the main menu and select Device.
  2. Expand the Special functions group.
  3. Select System parameter, then MainFrequency.
  4. Enter the value 1 and confirm (0 = 50 Hz, 1 = 60 Hz).
  5. Wait at least 60 seconds so that the value is stored permanently.
  6. Switch the device off and on again.
  7. Repeat the same path and check that 1 is now shown.

If the device is switched off too early, the old value is back after the restart – hence the final check.

NOTE

Some timing parameters of the device are counted in mains cycles. After changing to 60 Hz they therefore no longer correspond to the same times as at 50 Hz. Operation at 60 Hz has not been tested to the same extent as at 50 Hz – please coordinate its use with customer service.
