(2) Low Voltage Directive
We have self-confirmed our inverters as products compliant to the Low Voltage Directive (Conforming standard EN 50178) and affix the CE
marking on the inverters.
Outline of instructions
* Do not use an earth leakage current breaker as an electric shock protector without connecting the equipment to the earth. Connect the
equipment to the earth securely.
* Wire the earth terminal independently. (Do not connect two or more cables to one terminal.)
* Use the cable sizes on page 16 under the following conditions.
⋅ Surrounding air temperature: 40°C (104°F) maximum
If conditions are different from above, select appropriate wire according to EN60204 Appendix C TABLE 5.
* Use a tinned (plating should not include zinc) crimping terminal to connect the earth (ground) cable. When tightening the screw, be careful
not to damage the threads.
For use as a product compliant with the Low Voltage Directive, use PVC cable whose size is indicated on page 16.
* Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
* When using an earth leakage current breaker, use a residual current operated protective device (RCD) of type B (breaker which can detect
both AC and DC). If not, provide double or reinforced insulation between the inverter and other equipment, or put a transformer between the
main power supply and inverter.
* Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) condition of the power supply), overvoltage
category III (usable with the earthed-neutral system power supply, 400V class only) and pollution degree 2 or lower specified in IEC664.
⋅ To use the inverter of FR-A720-01150 (FR-A740-00570) or more (IP00) under the conditions of pollution degree 2, install it in the enclo-
sure of IP 2X or higher.
⋅ To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
⋅ To use the inverter of FR-A720-00900 (FR-A740-00440) or less (IP20) outside of an enclosure in the environment of pollution degree 2,
fix a fan cover with fan cover fixing screws enclosed.

FR-A740-00060, 00090
* 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 A1, B1, C1, A2, B2, C2) should be 30VDC, 0.3A. (Relay outputs are basically
isolated from the inverter internal circuit.)
* Control circuit terminals on page 6 are safely isolated from the main circuit.
