Note 1. When not using the servo amplifier as a UL/cUL Standard compliant product, K5 class fuse can be used.
2. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of
contacts) of 80ms or less.
3. S-N18 can be used when auxiliary contact is not required.
4. Use a molded-case circuit breaker which has the same or more operation characteristics than our lineup.
To prevent the servo amplifier from smoke and a fire, select a molded-case circuit
breaker which shuts off with high speed.
Always use one molded-case circuit breaker and one magnetic contactor with one
servo amplifier.
