Installation manual
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 and ROTIPHIZ.
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.
It is important that REX060, REX061 and REX062 chassis are
solidly earthed. Protective earth is a separate 4 mm 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.

Making of Ethernet connections

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.
