Quick start guide
Changing the active setting group will inevitably change the IED's operation. Be careful
and check regulations before making the change.
Avoid touching the enclosure of the coupling capacitor REX061 unit and the shunt
resistor REX062 unit. The surface may be hot during normal operation. The temperature
can rise 50°C in REX061 and 65°C in REX062 above the ambient temperature.
