Note 1. When using the servo amplifier as an EC/EN/UL/CSA standard compliant product, refer to appendix 4.
2. Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until
closure of contacts) of 80 ms or less.
3. When not using the servo amplifier as an EC/EN/UL/CSA standard compliant product, molded-case circuit breaker
of 30 A frame can be used.
4. A molded-case circuit breaker will not change to select regardless of use of a power factor improving AC reactor.
5. Use a molded-case circuit breaker which has the same or more operation characteristics than our lineup.
(2) For control circuit power supply
When the wiring for the control circuit power supply (L11, L21) is thinner than that for the main circuit
power supply (L1, L2, L3), install an overcurrent protection device (molded-case circuit breaker or fuse)
to protect the branch circuit.
