Mitsubishi Electric FR-A800 Series Instruction Manual page 566

*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).
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)
*2 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.
*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
• To use the electronic bypass function, the wiring terminals R1/L11 and S1/L21 must be connected to a separate power source
that does not go through MC1. Be sure to connect using a separate power supply.
• Be sure to provide a mechanical interlock for MC2 and MC3.
• Operation of magnetic contactor (MC1, MC2, MC3)

*1 For separated converter types, the X10 signal is assigned to the terminal MRS in the initial setting. For the MRS signal, set "24" to any of Pr.180
to Pr.189 (Input terminal function selection) to assign the function to another terminal.
*2 When the MRS signal is OFF, neither the commercial power supply operation nor the inverter operation can be performed.
*3 The CS signal operates only when the MRS signal is ON.
*4 STF (STR) operates only when the MRS and CS signals are both ON.
*5 Whether or not to enable reset input using the RES signal depends on the setting of Pr.75 Reset selection/disconnected PU detection/PU
stop selection. When the RES signal and another input signal are simultaneously input, the MC operation by the RES signal has a higher priority.
*6 MC1 opens at an inverter fault.
