Auxiliary circuit of Ekip-Com and HMI030
Description of Figures
Fig. 52 = Auxiliary circuits of the Ekip Com type interface unit and of the HMI030 type interface unit (see note E).
Notes
H) Having requested a Uaux insulated from earth, one must use “galvanically separated converters” in
compliance with 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, IEC 60364-41 and CEI 64-8.
