X1 connector. Connect each signal connector terminal of screw compression type
with one 0.14 to 6 mm
2
(AWG 35 - AWG 3) wire or with two 0.14 to 1.5 mm
2
(AWG 35 - AWG 15) wires.
Protective conductor terminal must be connected to the cubicle or station protective
earthing system. Electrical codes and standards require that protective earth cables
are green/yellow conductors with a cross section area of at least 2.5 mm
2
(AWG
14). The cubicle must be properly connected to the station earthing system. Use a
conductor with a core cross section area of at least 4 mm
2
(AWG 12).
6.2.3 Connecting and setting voltage inputs
GUID-BE3E0554-3E96-4489-B8C9-E62953853BB7 v4
The RIM module of REX060 has two analog output channels that shall be
connected to two voltage input channels of the IED.
If both stator and rotor protection are used, there are two possible methods to
perform the connection.
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.
