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.
