Ekip LCD
The LCD version of the protection trip unit can be requested for installations in particularly aggressive
environments (low temperatures, high degree of humidity, dust or chemical substances). The LCD version
differs from the version with touchscreen display in:
• Black and white LCD display.
• Menu navigation by buttons.
• The HOME button provides direct access to the page
Menu
. The
Measurements
pages can be accessed
using the ARROW UP and ARROW DOWN buttons from the page
Histograms
. (
Main Page
and
Measuring
Instruments
area are not available).
All the protection, measurement and accessory options are the same as those of the touchscreen version.
Rating Plug
The Rating Plug defines the rated current In necessary to set the current protections on the trip unit, since
these refer to In.
It is supplied with all Ekip trip units, mounted on a front connector dedicated and accessible to the user, and
can be replaced with trip unit off and circuit breaker open.
IMPORTANT: the replacement of the Rating Plug with trip unit on or circuit breaker
closed may cause malfunction of the trip unit, or unwanted opening of the circuit-
breaker.
NOTE:
a trip unit can be equipped with any Rating Plug with a maximum rated current equal
to Iu, i.e. the rated uninterrupted current of the circuit-breaker (indicated on the rating plate
of the circuit-breaker).
The trip unit continuously checks for the presence of the Rating Plug, signalling its absence or any assembly
or installation errors.
Once mounted, when the trip unit is energized, its installation is requested.
To activate the residual current protection on the Touch, Hi-Touch, G Touch and G Hi-Touch trip units, it is
necessary to mount a Rating Plug Rc. Rating Plug L = OFF, which allow you to deactivate the protection L
are also available.
Further details about assembly and the Rating Plug installation procedure are available on the website http://
