10.2 Auto circuit breaker (FAB, MCCB), earth leakage circuit breaker (ELCB) and magnetic contactor (MC) : Recommended Fuji’s
type
FAB or ELCB is installed on the power supply side for turning power supply and promptly cutting off a fault current such as short-circuit current.
MC is used when amplifiers are disconnected from the power supply with an external signal or in the case of power ON/OFF from remote
operation panels.
The types are applicable to the power supply capacity is up to 500 [kVA], specified cable diameter size with the wiring length within 20 [m] is
used, and ON/OFF of the primary side of one amplifier is performed. Connect an AC reactor if the power supply capacity exceeds 500 [kVA].

10.3 Surge suppressor (surge killer)
Shown below are recommended surge suppressors (for 250 [V] AC or less ) to be installed on peripheral devices (magnetic contactor,
solenoid, brake, etc. ) of amplifier.
DC equipment should be equipped with a diode for surge voltage suppression.
