When the relay is delivered from factory, it is preset ("7SJ602") and the version of the implemented firm
to operate with a rated frequency of 50 Hz. If the ware (e.g. "V3.00*").
rated system frequency is 60 Hz, this must be
matched accordingly. Switch-over to 60 Hz is ex Pressing the key \!leads to the main menu item "PA
