* This is the net value at the rated load. When actually selecting fuses, determine the capacity using the prescribed
derating.
** Operating characteristics (at 25°C): 2 seconds or more for 200%, 0.01 second or more for 700%
Note: 1. A fast-operating fuse cannot be used because the servo amplifier power supply is a capacitor input
type. A fast-operating fuse may blow when the power is turned ON.
2. XtraDrive servo amplifiers do not have built-in ground protection circuits. To configure a safer
system, install a ground fault interrupter with or without a circuit breaker for protection against
overload and short circuit conditions.
