FR-D740-080 or less
FR-D720S-070 and 100
Example for FR-D740-036
Note, the protection structure of the Inverter units is considered to be an IP00.
∗ On the input and output of the inverter, use cables of the type and size set forth in EN60204 Appendix C.
∗ The operating capacity of the relay outputs (terminal symbols A, B, C) should be 30VDC, 0.3A. (Relay outputs are
basically isolated from the inverter internal circuit.)
∗ Control circuit terminals on page 4 are safely isolated from the main circuit.
