Description of Figures
Fig. 23 = One Contact for electrical signalling of stored energy motor operator that can be operated remotely.
Fig. 53 = Auxiliary circuits of the electronic trip unit type Ekip LSI, Ekip LSIG or Ekip M-LRIU connected to
interface unit type Ekip Com and with actuator unit type MOE-E for the stored energy motor operator.
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.
