*1 Be careful of the capacity of the sequence output terminals. The applied terminals differ by the settings of Pr.190 to Pr.196 (Output terminal
function selection).
Output terminal capacity
Open collector output of inverter (RUN, SU, IPF, OL, FU) 24 VDC 0.1 A
Inverter relay output (A1-C1, B1-C1, A2-B2, B2-C2)
Relay output option (FR-A8AR)
*2 When connecting a DC power supply, insert a protective diode.
When connecting an AC power supply, use relay output terminals of the inverter or contact output terminals of the relay output option (FR-
A8AR).
*3 The applied terminals differ by the settings of Pr.180 to Pr.189 (Input terminal function selection).
*4 To use the signal, assign the function to the output terminal Pr.190 to Pr.195 (Output terminal function selection) of the converter unit. Always
set the negative logic for the ALM signal.
NOTE
• Use the electronic bypass function in External operation mode. In addition, the wiring terminals R1/L11 and S1/L21 must
be connected to a separate power source that does go through MC1. Be sure to connect using a separate power supply.
• Be sure to provide a mechanical interlock for MC2 and MC3.
