Note Description
For the zone selectivity and Local bus functions an auxiliary power supply is
A)
required (see diagram 1SDM000091R0001, figures 31-32).
When there are mixed auxiliary contacts, Q1 and Q2 are 400V, while Q3 and Q4 are
B)
24V. Then Q5, Q6 and Q7 are 400V while Q8, Q9 and Q10 are 24V.
C) Always supplied with Ekip Com module.
D) Always supplied with the motor for loading the closing springs in Figure 13.
Voltage transformer, mandatory in the case of external outlet sockets. External
E) outlet sockets, mandatory for systems with rated voltage greater than 690 V. The
maximum secondary rated voltage admitted is 230V.
The connections between the residual-current protection RC sensor and the poles of
connector X (or XV) of the circuit-breaker must be implemented with a screened four-
F)
pole cable with paired braided conductors (BELDEN 9696 paired type or equivalent),
no more than 10m in length.
With all the electronic protection trip units equipped with a display interface with
LSIG protections, protection against ground faults (Gext) is available through
a current sensor positioned on the star centre of the MV/LV transformer. The
G)
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.
Make the connection using the ABB cable supplied. There must be no break in the
cable. Use of other cables or extensions using intermediate terminal boxes is not
H) allowed. With a three-pole circuit-breaker, poles Ne+ and Ne- of connector X (or
XV) are short-circuited (unless the external neutral is present): realize short-circuit
connection if absent.
I) Obligatory in the case of presence of any Ekip module.
In the presence of Fig. 32, for circuit-breakers E2.2, E4.2 and E6.2, up to three
applications can be supplied between Fig. 41...58 taken only one; for E1.2 circuit-
L) breakers, instead, up to two applications can be supplied between Fig. 41...58
taken only once. In addition it is possible to duplicate an Ekip Com module that may
be selected choosing between Fig. 61...66.
Opening and closing commands via the Ekip Actuator module can be obtained with
M)
coils YC and YO, with 110-120VDC and 240-250VAC maximum voltage values.
N) Use cable type Belden 3105A or equivalent.
In the presence of several Ekip Com modules with withdrawable version circuit-
O)
breakers, the contact S75I/5 should be connected only once to a single module.
The auxiliary voltage Uaux allows all the functions of the Ekip electronic protection
P) trip units to be activated "Galvanically separated converters" conforming to standard
IEC 60950 (UL 1950) or the equivalent standards.
Belden type 3105A or equivalent cables must be used, with a maximum length of
Q)
15m.
R) Suggested RJ45 cable: CAT6 STP
For the EIA RS485 serial interface connection, see the "Technical Application
S)
Handbook - vol. 9: Communication with ABB circuit-breakers via BUS"
Short circuit the 120 Ω on terminals if you wish to insert a terminating resistor on the
T)
Local Bus.
Use Belden type 3105A or equivalent cables. For further details see the White
U)
Paper 1SDC007412G0201 "Communication with SACE Emax 2 circuit-breakers".
Use Belden type 3084A or equivalent cables. For further details see the White Paper
V)
1SDC007412G0201 "Communication with SACE Emax 2 circuit-breakers".
Ekip Supply cannot be used to supply the electronic trip unit via terminals K1 and
Z)
K2.
AA) For W3 and W4 connection see figure 31 or 32
Use a twisted pair shielded and stranded cable type BELDEN 8762/8772 or
AB) equivalent. The shield must be earthed on the selectivity input side (for zone
selectivity) or on both sides (for others applications).
AC) The maximum secondary rated voltage admitted is 120V.
(1)
Only for E2.2-E4.2-E6.2.
