6 - Operating characteristics

Introduction Ekip Touch has been developed and certified to work in specific environmental, electrical, and
mechanical conditions. All the information is available in the Technical Catalog (see page 4).
The following paragraphs only describe the electrical and power characteristics for correct
operation of Ekip Touch and related electronic accessories.
Electrical
The correct operation of Ekip Touch is guaranteed with primary power and voltage in the
characteristics
designated ranges and having well-defined characteristics:
Parameter
Primary power
Primary voltage
Rated frequency
Peak factor
Ekip Touch can also be powered directly by the internal power sensors:
Parameter
Minimum three-phase power on startup
Auxiliary power Ekip Touch can be connected to an external auxiliary power source, useful for enabling some
supply functions such as communication on the Local Bus, recording of manual operations, some
measurements, and the data logger.
The auxiliary power supply can be supplied by modules from the Ekip Supply range (see page
130 for more operational details) or be powered directly through the side terminal board.
The direct connection must guarantee the following operating conditions:
Parameter
Voltage
Tolerance
Maximum wave
Maximum surge current @ 24 V
Maximum rated power @ 24 V
Connecting cable

Compliant with IEC 60947-2
NOTE: range referred to each phase; In refers to the rated size of the Trip unit, available
in models ranging from 40 A to 250 A.
IMPORTANT: if the Trip unit is connected directly the power supply must be
galvanically isolated and must guarantee the insulation characteristics referred
to in IEC 60950 (UL 1950) or their equivalent
Rev. B
