Safety Information
This manual does not constitute a complete index of all required safety measures for operation of the equip-
ment (module, device), as special operational conditions may require additional measures. However, it
comprises important information that should be noted for purposes of personal safety as well as avoiding
material damage. Information that is highlighted by means of a warning triangle and according to the degree
of danger, is illustrated as follows.
!
DANGER
Danger indicates that death, severe personal injury or substantial material damage will result if proper
precautions are not taken.
²
!
WARNING
indicates that death, severe personal injury or substantial property damage may result if proper precautions
are not taken.
²
!
CAUTION
indicates that minor personal injury or property damage may result if proper precautions are not taken. This
particularly applies to damage to or within the device itself and consequential damage thereof.

NOTE
indicates information on the device, handling of the device, or the respective part of the instruction manual
which is important to be noted.

WARNING
Qualified Personnel
Commissioning and operation of the equipment (module, device) as set out in this manual may only be
carried out by qualified personnel. Qualified personnel in terms of the technical safety information as set
out in this manual are persons who are authorized to commission, activate, to ground and to designate
devices, systems and electrical circuits in accordance with the safety standards.
Use as prescribed
The operational equipment (device, module) may only be used for such applications as set out in the cata-
logue and the technical description, and only in combination with third-party equipment recommended or
approved by Siemens.
The successful and safe operation of the device is dependent on proper handling, storage, installation,
operation, and maintenance.
When operating an electrical equipment, certain parts of the device are inevitably subject to dangerous
voltage. Severe personal injury or property damage may result if the device is not handled properly.
Before any connections are made, the device must be grounded to the ground terminal.
All circuit components connected to the voltage supply may be subject to dangerous voltage.
Dangerous voltage may be present in the device even after the power supply voltage has been removed
(capacitors can still be charged).
Operational equipment with open circuited current transformer circuits may not be operated.
The limit values as specified in this manual or in the operating instructions may not be exceeded. This
aspect must also be observed during testing and commissioning.
²
Typographic and Symbol Conventions
The following text formats are used when literal information from the device or to the device appear in the
text flow:
Parameter Names
Designators of configuration or function parameters which may appear word-for-word in the display of the
device or on the screen of a personal computer (with operation software DIGSI), are marked in bold letters in
monospace type style. The same applies to titles of menus.
1234A
Parameter addresses have the same character style as parameter names. Parameter addresses contain the
suffix A in the overview tables if the parameter can only be set in DIGSI via the option Display additional
settings.
Parameter Options
Possible settings of text parameters, which may appear word-for-word in the display of the device or on the
screen of a personal computer (with operation software DIGSI), are additionally written in italics. The same
applies to the options of the menus.
Indications
Designators for information, which may be output by the relay or required from other devices or from the
switch gear, are marked in a monospace type style in quotation marks.
Deviations may be permitted in drawings and tables when the type of designator can be obviously derived
from the illustration.
The following symbols are used in drawings:

Overall Operation
The numerical SIPROTEC 7SJ62/64 multifunction protection devices are equipped with a powerful microproc-
essor. It allows all tasks to be processed digitally, from the acquisition of measured quantities to sending
commands to circuit breakers. Figure 1-1 and Figure 1-2 illustrate the basic structure of the devices 7SJ62 and
7SJ64.
Analog Inputs
The measuring inputs (MI) convert the currents and voltages coming from the instrument transformers and
adapt them to the level appropriate for the internal processing of the device. The device provides four current
inputs. Depending on the model, the device is also equipped with three or four voltage inputs. Three current
inputs serve for input of the phase currents. Depending on the model, the fourth current input (ΙN) may be
used for measuring the ground fault current ΙN (current transformer neutral point) or for a separate ground
current transformer (for sensitive ground fault detection ΙNs and directional determination of ground faults).

Figure 1-1 Hardware structure of the numerical multi-functional device 7SJ621/622
Voltage inputs can either be used to measure the three phase-to-ground voltages, or two phase-to-phase
voltages and the displacement voltage (VN voltage). It is also possible to connect two phase-to-phase voltages
in open-delta connection.
The 4 voltage transformers of 7SJ623, 7SJ624, 7SJ625, 7SJ626 and 7SJ64 can either be applied for the input
of 3 phase-to-ground voltages, one displacement voltage V0 or a further voltage for the synchronization func-
tion.
