Note Description
With all the electronic protection releases equipped with a display interface
with LSIG protections, protection against earth faults (Gext) is available
through a current sensor positioned on the star centre of the MV/LV
G) transformer. The connection between terminals 1 and 2 of the UI/O current
transformer and the Ge+ and Ge- poles of connector X (or XV) must be
implemented with two-pole shielded stranded cable (BELDEN 9841 type or
equivalent) no more than 15 m in length.
The connection must be implemented with the 2m supplied cable. With
H) three-pole circuit-breakers Ne+ and Ne- poles of connector X (or XV) must
be short-circuited if the external neutral is not present.
I) Mandatory if any Ekip module is present.
Only for withdrawable circuit breakers as an alternative to diagrams
31-32-33.
J)
NOTE: Ekip Fan 24VDC occupies the space of the Ekip Supply and
of a Module slot in the terminal box.
Only for withdrawable circuit breakers as an alternative to the diagrams
31-32-33.
K)
NOTE: Ekip Fan 220VAC occupies the space of the Ekip Supply and
two Module slots in the terminal box.
In the presence of diagram 32, up to three applications can be provided
between diagrams 41... 58 taken only once. In addition, it is possible to
L)
duplicate an Ekip Com module that may be selected choosing between
diagrams 61...66.
In the presence of diagram 33, up to three applications can be provided
M) between diagrams 41... 58 taken only once. It is possible to duplicate the
selected Ekip Com module choosing between diagrams 61...66.
In the presence of diagram 34, only one application among diagrams 41...
N)
58 can be provided.
In the presence of multiple Ekip Com modules with circuit-breakers in
O) withdrawable version, the contact S75I/5 must be connected only once on
a single module.
The auxiliary voltage Uaux allows all the functions of the EKIP electronic
protection releases to be activated "Galvanically separated converters"
conforming to standard IEC 60950 (UL 1950) or the equivalent standards,
P)
able to guarantee current in the common mode or leakage current (see IEC
478/1, CEI 22/3) that is no more than 3.5 mA (IEC 60364-41 and CEI 64-8)
must be used since the Uaux must be isolated from the earth.
Q) The maximum length of the cable for the local bus is 15 metres.
