3.1
Installation and Connections
WARNING!
Warning of improper transport, storage, installation, and application of the
device.
Non–observance can result in death, personal injury or substantial property damage.
Trouble free and safe use of this device depends on proper transport, storage, instal-
lation, and application of the device according to the warnings in this instruction
manual.
Of particular importance are the general installation and safety regulations for work in
a high-voltage environment (for example, ANSI, IEC, EN, DIN, or other national and
international regulations.) These regulations must be observed.
3.1.1
Configuration Information
Requirements
For mounting and connection, the following conditions and limitations apply:
The rated device data is checked as recommended in the SIPROTEC
®
4 System
Manual. The compliance these data is verified with the power system data.
Connection vari-
ants
Connection examples for the current and voltage transformer circuits are given in the
Appendix.
Currents/Voltages
As the voltage inputs of the 6MD665 device have an operating range from 0 to 170
V, this means that phase-phase voltages can be assessed up to
√
3 · 170 V = 294 V.
Binary inputs and
outputs
The configuration of the binary inputs and outputs, i.e. the individual adaptation to the
system conditions, is described in /1/. The connections to the system are dependent
on this actual configuration.
3.1.2
Hardware Modifications
3.1.2.1
General
General
Hardware modifications concerning, for instance, rated currents, the control voltage
for binary inputs or termination of serial interfaces might be necessary. Follow the pro-
cedure described in this subsection, whenever hardware modifications are done.
Auxiliary voltage
The various input voltage ranges (60/110 V DC and 220 to 250 V DC) of the auxiliary
voltage can be changed to one another by changing the plug-in jumpers. When the
