currents.
The operating conditions for proper operation are listed below:
Parameter
Minimum three-phase turn-on current
Rated frequency
Harmonic distortion
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 61), 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.
