Note 1. When not using the servo amplifier as a UL/CSA Standard compliant product, K5 class fuse can be used.
2. Be sure to use a magnetic contactor with an operation delay time of 80ms or less. The operation delay time is the time interval
between current being applied to the coil until closure of contacts.
