Connection Diagram - Mitsubishi Electric FR-CC2-H355K Instruction Manual

Connection diagram
To prevent restart at fault occurrence, connect terminals So (SO) and SOC to the reset button, which are the feedback input
terminals of the safety relay module.

When not using the safety stop function, short across terminals S1 and PC, S2 and PC, and SIC and SD to use the inverter. (In the initial status,
terminals S1 and PC, S2 and PC, and SIC and SD are respectively shorted with shorting wires.)


When the internal safety circuit is operated normally (no faults occurs), terminal So (SO) and the SAFE signal remains ON until "E.SAF" is
displayed. Terminal So (SO) and the SAFE signal turns OFF when "E.SAF" is displayed.

SA is displayed when the terminals S1 and S2 are identified as OFF due to the internal safety circuit failure.

If another fault occurs at the same time as E.SAF, the other fault can be displayed.

If another warning occurs at the same time as SA, the other warning can be displayed.

&&The table shows the signal status in positive logic. &&In negative logic, the signal status is opposite.

To assign the function of the SAFE signal to an output terminal, set either value shown in the following table in any of Pr.190 to Pr.196 (Output
terminal function selection).
