Note: !This switch-over function is used in the external operation mode. Always connect terminals R1, S1 (L11, L21) to a different power supply (power supply different from the one for MC1) to ensure proper operation.

!MC2 and MC3 must be mechanically interlocked.

*1. Note the sequence output terminal capacities. The terminals used depend on the Pr. 190 to Pr. 194 settings.

Output Terminal Capacity	Permissible Output Terminal Load
Inverter's open collector outputs	24VDC 0.1A
(IPF, OL, FU)
FR-A5AR (option output)	230VAC 0.3A
	30VDC 0.3A

*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.

*3. The terminals used depend on the Pr. 180 to Pr. 186 settings.
