Some settings are required for the analog voltage inputs. Set the voltage ratio for the inputs to
1/1, for example, VTSecx = 100 V VTPrimx = 0.1 kV
The analog inputs are linked to a pre-processor block in the Signal Matrix Tool. This pre-processor
block must have the same cycle time, 8 ms, as the function blocks for STTIPHIZ (64S) and
ROTIPHIZ (64R).
The default parameter settings are used for the pre-processor block.
It is possible to connect two REG670 IEDs in parallel to the REX060 injection unit in order to obtain
redundant measurement in the two IEDs. However, at commissioning, both IEDs must be
connected during the calibration procedure.

Making of Ethernet connections

6.3.1

Connecting station communication interfaces

The numerical module (NUM) provides up to four Ethernet ports (one basic and three optional),
and the optical Ethernet module (OEM) provides two additional Ethernet ports. These ports are
used for IEC 61850 or DNP3 communication. The serial communication module (SLM) provides
four optical ports which are used for LON, SPA, IEC 60870-5-103 or DNP3 communication.
• Ports X301 to X304 on the NUM module and ports X3061 and X3062 on the OEM module are
used for IEC 61850-8-1 and IEC/UCA 61850-9-2LE communication. Ports X301/X302, X303/
X304 and X3061/X3062 are to be used in pairs for redundant communication. The optical port
connectors are of LC type and the galvanic connectors are of RJ45 type.
• Optical ports X311 A and B on the SLM module are used for SPA, IEC 60870-5-103 or DNP3
communication. The port connectors are of ST (glass) or HFBR Snap in (plastic) type.
• Optical ports X311 C and D (Tx, Rx) on the SLM module are used for LON communication. The
port connectors are of ST (glass) or HFBR Snap in (plastic) type.
Optical fibers have Transmission (Tx) and Reception (Rx) connectors, and they should be attached
to the Tx and Rx connectors on the SLM module (Tx cable to Rx connector, Rx cable to Tx
connector). Connectors are usually color coded: connect blue or dark grey cable connectors to blue
or dark grey (receive) back-side connectors. Connect black or grey cable connectors to black or
grey (transmit) back-side connectors.

Installation manual
It is important that REX060, REX061 and REX062 chassis are solidly grounded.
Protective ground is a separate 0.15" screw terminal that is a part of the metallic
chassis.
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.
