Connecting
1. The recommended connection require four analog channels of the IED: two IED voltage
channels are used for the measured quantities for ROTIPHIZ; two more IED voltage channels
are used for the measured quantities for STTIPHIZ.

2. It is possible to use a mixed connection that requires only two IED voltage channels for both
ROTIPHIZ and STTIPHIZ. REX060 outputs are connected in series. This connection is not
recommended and can be used only in applications where it is prove the possibility to use it.
the use of this connection leads to reduced performances of both ROTIPHIZ and STTIPHIZ.
