3 - Ekip Multimeter
Ekip Multimeter is a remote display panel-front module with touchscreen display allowing the parameters of
the Trip unit to which it is connected via local bus to be displayed and edited.
Up to four
Ekip Multimeter modules can be connected to the same Trip unit. On the other hand, the module
can only be connected to one Trip unit.
The rear connector allows the unit to be supplied in two different ways:
Terminals / supply
voltage
Frequency Power input Inrush current
21,5 ÷ 53 VDC - Maximum 10W Maximum 2 A for 20 ms
105 ÷ 265 VAC/DC 45 ÷ 66 Hz Maximum 10 VA/W Maximum 2 A for 20 ms
IMPORTANT: AC and DC supplies cannot be present at the same time
The module provides for 24 VDC auxiliary voltage (terminals 24Vout L+ and L-), which can be used to directly
supply the Trip unit.
WARNING! Ekip Multimeter is sized to supply the Trip unit alone, without additional
modules: if auxiliary voltage is used via module, it must be connected directly
to the terminal box of the CB without the possibility of using Ekip Supply or other
modules
Connections
Belden 3105A cables or equivalent, up to 15 m in length, must be used for the local bus and auxiliary supply.
The cable shield must be earthed on both sides of the connection.

4 - Rc Toroid
Rc is an external differential current sensor which can be installed on Ekip Touch Trip units equipped with Rc
Rating Plug
.
When Ekip Touch is being programmed, check in the Settings - Circuit breaker - Ground protection menu to
make sure that the toroid is present (page 37, the configuration menu of the Rc protection parameters must
be activated in the
Advanced menu (page 35).
IMPORTANT: the toroid can be choosen as an alternative to the S.G.R. one: protections
Gext, MDGF and Rc are alternatives to each other
Further details about the Rc toroid connection are available in ABB Library, especially in document
1SDH001000r0521 .
5 - S.G.R. Toroid
S.G.R. or Source Ground Return is an external single-pole current sensor available for LSIG version Ekip
Touch Trip units
When Ekip Touch is being programmed, check in the
Settings - Circuit breaker - Ground protection menu to
make sure that the toroid is present (page 37, the configuration menu of the Gext protection parameters must
be activated in the
Advanced
menu (page 35).
IMPORTANT: the toroid can be choosen as an alternative to the Rc one; protections
Gext, MDGF and Rc are alternatives to each other
Further details about the S.G.R. toroid connection are available in ABB Library, especially in document
1SDH001000r0507 .
