The XT2 and XT4 moulded-case circuit-breakers, equipped with Ekip LSI, Ekip LSIG
or Ekip M-LRIU trip unit and Ekip Com dialogue module, can be integrated in supervision systems
for control and management of electrical and technological plants.
With XT2 and XT4, equipped with thermomagnetic trip units, Ekip Com dialogue module and Elec-
tronic Motor, it is possible to read the state of the circuit-breaker remotely and to operate it.
Protocols available, for communication on bus
(G5.4)
network with circuit-breakers XT2 and XT4, are:
Q Modbus RTU (standard protocol of ABB SACE);
Q ProfiBus-DP (usable with ABB SACE devices, jointly with EP010 accessory);
Q DeviceNet (usable with ABB SACE devices, jointly with EP010 accessory).
Necessaries accessories for communications are:
Q Ekip Com communication module and electronic auxiliary contacts (1Q + 1SY) included in the
Ekip Com module. For further details about the Ekip Com communication module, see the
paragraph dedicated to this in the Accessories chapter;
Q Electronic motor operator MOE-E;
Q EP010- Field Bus Plug.
Configuration 1: Supervision (Electronic trip unit and Ekip Com)
Positioned in the right-hand slot of the circuit-breaker, the Ekip Com accessory connects to the Ekip
LSI, Ekip LSIG, Ekip E-LSIG or Ekip M-LRIU trip unit via connector supplied. Six cables come out
of Ekip Com, of which two are required for auxiliary supply, two for connection to the Modbus and
two for connection to Internal Bus.
This configuration allows you to:
Q read the measurements and settings from the electronic trip unit in remote mode;
Q program the electronic trip unit in remote mode;
Q know the state of the circuit-breaker (Open/Closed/Tripped) in remote mode;
Q visualize locally on HMI 030 all the relevant information of the CB.
Consult the Electric Diagrams chapter for further details about wiring.
