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, VDE, IEC, EN, DIN, or other national and
international regulations). These regulations must be observed.
For installation and connections the following conditions must be met:
The rated device data has been tested as recommended in the SIPROTEC 4 System
Description and their compliance with the Power System Data is verified.
General diagrams are shown in the Appendix A.2. Connection examples for current
and voltage transformer circuits are provided in Appendix A.3. It must be checked that
the settings for configuration (Subsection 2.1.3) and the Power System Data (Subsec-
tion 2.1.4) match the connections to the device.
The setting of the protected object (address 105) must correspond to the object to
be protected. An incorrect setting may cause unforeseeable reactions by the device.
Please note that for auto-transformers PROT. OBJECT = autotransf. and not
3-phase transf. must be set. For single-phase transformer , the centre phase L2 is
not used.
Connection of the CT currents depends on the mode of application.
With three-phase connection the three phase currents are assigned to the measuring
locations. Connection examples for the various protected objects are provided in the
Appendix A.3. Please refer also to the Appendix A.2 for the general diagrams that
apply to this device. Check that the measuring locations are correctly assigned to the
sides of the protected object and to the measuring inputs on the device.
With two-phase connection of a single-phase transformer the centre phase will not be
used. Appendix A.3 shows connection examples. Even if there is only one current
transformer, both phases (IL1and IL3) will be used. Also observe the General Dia-
grams in annex A.2 that apply to the current device.
