                        Introduction Ekip Touch has been developed and certified to function in specific environmental, electrical and mechanical
                                    conditions; full details are available in the Technical catalog.
                                    The following sections describe the electrical and power supply characteristics that enable Ekip Touch and
                                    the relative electronic accessories to operate correctly.



             Electrical characteristics The Ekip Touch measurement and protection functions described in this document are provided with primary
                                    voltage and current values within the following nominal ranges:
                                     Parameter                      Rated operating range
                                     Primary current                0,004 ÷ 16 In  (1)
                                     Primary voltage                5 ÷ 690 V AC  (2)
                                     Rated frequency                45 ... 55 Hz (with fn= 50 Hz) / 54 ... 66 Hz (with fn= 60 Hz)
                                     Peak factor                    Complying with standard IEC 60947-2

                                    (1)  range with reference to each phase; In refers to the rated size defined by the Rating plug installed on the Trip
                                    unit, available in models from 100 A to 6300 A
                                    (2)  rated highest line-to-line voltage connected directly to Trip unit, also to sockets inside the CB; external
                                    transformers must be used for higher voltage values, consult the chapter dedicated to the Measurement
                                    modules


                         Self-supply The internal current sensors are able to supply the Trip unit directly; versions Hi-, G, G Hi- are also fitted
                                    with the Measurement enabler with voltage sockets module, which allows the Trip unit to be supplied by the
                                    installation voltages as well:
                                     Parameter                      Operating limits
                                                                    > 30 A (E1.2-E2-2-E4.2 with Rating Plug < 400 A)
                                     Minimum three-phase turn-on current  > 80 A (E1.2-E2-2-E4.2 with Rating Plug ≥ 400 A)
                                                                    > 160 A (E6.2)
                                     Minimum three-phase turn-on voltage  > 80 V




               Auxiliary power supply Ekip Touch can be connected to an external auxiliary supply source, which is useful when certain functions
                                    such as communication via Local Bus, recording manual operations,  certain measurements and the
                                    datalogger must be activated.
                                    The auxiliary supply can be provided by modules from the Ekip Supply range or by direct connection to the
                                    terminal box.
                                    Direct connection must guarantee the following operating conditions:
                                     Parameter                      Operating limits
                                     Voltage                        24 V DC galvanically isolated
                                     Tolerance                      ±10%
                                     Maximum ripple                 ±5%
                                     Maximum inrush current @ 24 V  10 A per 5 ms
                                     Maximum rated power @ 24 V     4 W
                                                                    Insulated with grounding cable (same characteristics as Belden
                                     Connection cable
                                                                    3105A/B or higher)


                                           IMPORTANT: if connection is direct, the power supply must be galvanically insulated
                                           and provide the insulation characteristics established by standard IEC 60950 (UL
                                           1950) or equivalent.
