5.8.11 Magnetic Contactor
5-82
(3) Magnetic Contactor with Coil Drive Unit for Three-phase 400 V SERVOPACKs
The magnetic contactors for three-phase 400 V SERVOPACKs include coil drive unit.
The rated voltage of the operating coil in the coil drive unit is 24 VDC.
Maintain the power supply voltage within the specified range. The voltage below the allowable range causes
malfunction, resulting in the magnetic contacts seizing or the coil burning out.
If a voltage above 24 V is applied, the unit will be damaged. Confirm the voltage at the trial operation after
installation.
