(2) Low Voltage Directive
We have self-confirmed our inverters as products compliant to the Low Voltage Directive (Conforming standard EN 61800-
5-1) and affix the CE marking on the inverters.
 Outline of instructions
 Do not use an earth leakage circuit breaker as an electric shock protector without connecting the equipment to the earth.
Connect the equipment to the earth securely.
 Wire the earth (ground) terminal independently. (Do not connect two or more cables to one terminal.)
 Use the cable sizes on page 8 under the following conditions.
Surrounding air temperature: 40°C maximum
If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5.
 Use a tinned (plating should not include zinc) crimp terminal to connect the earth 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 on page 8.
 Use the molded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
 When using an earth leakage circuit 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) specified
in IEC60664.
To use the inverter under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
To use the inverter outside of an enclosure in the environment of pollution degree 2, fix the fan cover with fan cover
fixing screws enclosed.
FR-E740-095SC or lower
FR-E720S-050SC to 110SC
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 output has basic
isolation from the inverter internal circuit.)
 Control circuit terminals on page 6 are safely isolated from the main circuit.


For the installation at an altitude above 1000m up to 2500m, consider a 3% reduction in the rated current per 500m increase in altitude.
