Ekip Multimeter; External Neutral - ABB SACE Tmax XT2 User Manual

61 - Ekip Multimeter

Ekip Multimeter is a module for remote viewing equipped with a touchscreen display that makes
it possible to view and change parameters of the Trip unit it is connected to via the local bus.
Up to four Ekip Multimers can be connected to the same Trip unit. In contrast, the module can
be connected to only one Trip unit.
Electrical characteristics
The rear connector allows powering the unit with two different electrical solutions:
Terminals / supply voltage
21.5...53 VDC
105...265 VAC/DC
The module offers an auxiliary voltage of 24 VDC (terminals 24Vout L+ and L-) that can be used
to directly supply the Trip unit.
Connections
For the local bus and the auxiliary power supply, Belden 3105A or equivalent cables with a
maximum length of 15 m must be used. The cable shield must be grounded on both sides of the
connection.

62 - External neutral

It is a current sensor for the neutral pole outside the circuit breaker for CB 3P to establish
neutral protection by connecting to the Trip unit.
To configure the sensor presence and the protection see pages 29 e 44.
More information on the connection of the external neutral can be found at

IMPORTANT: AC and DC power supplies cannot be present at the same time
CAUTION! Ekip Multimeter is sized to power only the Trip unit without additional
modules. If the auxiliary module voltage is used, it must be connected directly to
the CB terminal board, without the possibility of using Ekip Supply or other
modules
