Note: !This switch-over function is used in the external operation
mode. Always connect terminals R1, S1 (L
different power supply (power supply different from the one
for MC1) to ensure proper operation.
!MC2 and MC3 must be mechanically interlocked.

*2. When connecting an AC power supply, connect the FR-A5AR option
and use the contact output.
When connecting a DC power supply, install the following protective
diode.
