Primary operating currents
The Ekip Dip release can be powered directly by the internal current sensors, with clearly
defined primary currents.
The operating conditions for proper operation are listed below:
Parameter
Minimum three-phase turn-on current
Rated frequency
Harmonic distortion
Auxiliary power supply
The Ekip Dip release can be connected to an external auxiliary power source, useful for
activating some functions such as communication on the local bus or recording of manual
operations.
The auxiliary power can be supplied by the modules of the Ekip Supply range (for further
functional details, see page 162), or with direct connection to a terminal box.
The direct connection must be made guaranteeing the operating following conditions:
Parameter
Voltage
Tolerance
Maximum ripple
Maximum inrush current @ 24 V
Maximum rated power @ 24 V
Connection cable
IMPORTANT:
• With a direct connection, the power must be galvanically isolated and must
ensure the insulation characteristics retrieved from IEC 60950 (UL 1950)
or equivalent standards that ensure a common mode current, or leakage
current, (see IEC 478/1, CEI 22/3) no greater than 3.5 mA.
• The Ekip Supply modules do not require galvanic insulation.
