SIF5600 - Manual - 03 - 2008
Identification
Identifying labels:
- a transparent adhesive label applied to the front panel comprising the complete code, the list of
protective functions, the operational range of the auxiliary supply voltage and t
he CE mark;
- connection diagram on the right hand side;
- the test certification label including the serial number and the test operators initials.
Current connections
The current input circuits do not have any automatic short-circuit devices for the current trans-
former secondary circuits, consequently it is necessary to avoid disconnecting such connections
prior to performing a short-circuiting step outwith the relay.
It
is recommended that cabling of a suitable thickness be used in order to limit wear of the CT sec-
ondary circuits.
Environmental Conditions
The SIF5600 relay must be used under the environmental conditions indicated in the technical speci-
fications.
For use under any other conditions, special arrangement must be made prior to commissioning (air
conditioning systems, humidity control etc...).
In the presence of any potentially polluting substances (dusts, corrosive substances etc.) appropri-
ate filter systems must be used.
Symbols
The manual uses CEI/IEC standardised symbols wherever available:
e.g.: 50 = ANSI code for Instantaneous overcurrent relay protective function
T
he following typographic formats are used in this manual:
Menu titles are highlighted in bold
e.g.: “Set”
E
xamples of display messages are shown using the Courier font,
e.g.: “SIF DK5600”
