System Design and Installation
For a simultaneous inrush for multiple Servo Drivers, select a no-fuse-breaker with a 20-ms allowable
current greater than the total inrush current shown in the following table for the applicable Servomotor
models.

D Surge Absorbers
Use surge absorbers to absorb surges from power supply input lines due to lightning, abnormal volt-
ages, etc. When selecting surge absorbers, take into account the varistor voltage, the amount of surge
immunity, and the amount of energy resistance. For 200-V AC systems, use surge absorbers with a
varistor voltage of 470 V. The surge absorbers shown in the following table are recommended.

Note 1.
Refer to the manufacturers' documentation for operating details.
Note 2. The surge immunity is for a standard impulse current of 8/20 µs. If pulses are wide, either decrease the
current or change to a larger-capacity surge absorber.
