CAUTION

1.Use sink logic (factory setting) when the FR-HC is connected. The FR-HC cannot be connected when source logic is selected.

2.The power input terminals R, S, T must be open. Incorrect connection will damage the inverter. Opposite polarity of terminals N, P will damage the inverter.

3.The voltage phases of terminals R, S, T and terminals R4, S4, T4 must be matched before connection.

4.Use Pr. 60 to Pr. 63 (input terminal function selection) to assign the terminals used for the RES and MRS signals.

5.Do not insert NFB between terminals P-N (P - P, N - N)

6.The N terminal is not provided for the FR-S520E-0.1K to 0.75K.
