wires.
Grounding (PE). Protective earth is a separate 4 mm screw terminal.
5.5.3 Connecting and setting voltage inputs
There are two different methods for connecting the IED to the REX060 injection
unit if both stator and rotor protection is used, either using two analog input
channels on the IED for both rotor and stator voltage and current measurements, or
two analog IED input channels for the rotor and another two IED channels for the
stator measurements.
1. The same voltage input is used for both stator and rotor voltage measurement
and another voltage input is used for both stator and rotor current
measurement. The REX060 outputs to IED are connected in series.

2. Two different voltage inputs are used for stator and rotor voltage measurement
and two other voltage inputs are used for stator and rotor current measurement.
This means that the inputs for STTIPHIZ is separated from the inputs for
ROTIPHIZ.
