Mitsubishi Electric FR-F820-00077 Instruction Manual page 507

Parameters
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)
Inverter relay output (A1-C1, B1-C1, A2-B2, B2-C2)
Relay output option (FR-A8AR)
When connecting a DC power supply, insert a protective diode.
When connecting an AC power supply, use the relay output option (FR-A8AR) and use contact
outputs.
The applied terminals differ by the settings of Pr. 180 to Pr. 189 (input terminal function selection).
To use the signal, assign the function to the output terminal Pr. 190 to Pr. 195 (output terminal
function selection) of the converter unit. It is recommended, that the wiring of the ALM signal is
always proof against wire breaks. High signal = no fault.
NOTES 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.
