CAUTION
⋅ Use the commercial power supply switchover function in external operation mode. Be sure to connect the other power
supply since the function is not performed normally unless the connection terminals R1/L11, S1/L21 are not connected to
the other power supply (power supply that does not pass MC1).
⋅ Be sure to provide mechanical interlocks for MC2 and MC3.
