11. Options and peripheral devices
(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.
