For Control Circuit Power Supply - Mitsubishi Electric -MR-CV User Manual

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, fuse, etc.) to protect the branch circuit. The following
table lists the selection of overcurrent protection devices (molded-case circuit breaker, fuse, etc.) that are connected only to
the converter unit. When crossing over the wiring of the control circuit power supply, refer to the drive unit/servo amplifier
user's manual and instruction manual.
