Menu The specific configuration area will activate in the Settings - Modules - Ekip Measuring menu if the Measurement
module is detected correctly by Ekip Touch.
The following parameters can be configured in this menu:

Parameter Description Default
Voltage Transf. Selects the presence or absence of the external transformer Absent
Available in the absence of a transformer; defines rated voltage Un.
Rated voltage The value is given as absolute value (Volts) and can be set within 400 V
the range: 100 V to 690 V with variable steps.
Available in the presence of a transformer; defines rated voltage Un
of the installation.
Primary voltage 400 V
The value is given as absolute value (Volts) and can be set within
the range: 100 V to 1150 V with variable steps.
Available in the presence of a transformer; defines the secondary
voltage of the transformer.
Secondary voltage 100 V
The value is given as absolute value (Volts) and can be set within
the range: 100 V to 230 V with variable steps.
Defines the power flow required for D protection; there are 2
options available (page 73):
Positive Power flow • High → Low: the power flows from the low terminals to the high High → Low
ones (load connected low)
• Low → High: opposite power flow (load connected high)
Available with 3P CB; allows the presence of the external Neutral
to be enabled.
Neutral connection Absent
NOTE: presence of the neutral activates phase voltage
measurement

About The About-Modules menu contains the specific menu of the module with the serial number and version of
the module itself.

Test The Measurement module must be disconnected from Ekip Touch (according to the procedure available on
the front label) and the external sockets must be disconnected from the terminal box in the following cases:
Module Measurement enabler
Test Module Measurement enabler (1)
with voltage sockets
Dielectric test x
Isolation between phases x x

(1) disconnection to be performed also in the presence of Ekip Touch without Measuring package

Replacement The Measurement module can be replaced on its Trip unit, for details consult document 1SDH001000r0528.
If the Measurement module is replaced, module change is indicated on the display by an alarm in the
diagnosis bar when the apparatus is powered for the first time.
To install the new module:
• Confirm the installation module which appears automatically on the display
• Execute manual control, available in the Settings menu (page46)
WARNING! if the Class 1 Power & Energy Metering package is present, module
replacement could impair the performance values indicated on page 117; consult
ABB to assess solutions able to comply with your requirements
