Note 1. When having the servo amplifier comply with the IEC/EN/UL/CSA standard, refer to app. 4.
2. Use a magnetic contactor with an operation delay time (interval since a current is applied to the coil until the contact closes) of
80 ms or shorter.
3. S-N18 can be used when auxiliary contact is not required.
4. Use a molded-case circuit breaker having the operation characteristics equal to or higher than Mitsubishi Electric general-
purpose products.
The Type E Combination motor controller can also be used instead of a molded-case circuit breaker.

Select a molded-case circuit breaker with a fast shut-off time to prevent smoke or
a fire.
Always use one molded-case circuit breaker and one magnetic contactor with one
servo amplifier.
