APPENDIX

A.1.2 Low Voltage Directive

We have self-confirmed our inverters as products compliant to the Low Voltage Directive (conforming standard

EN 61800-5-1) and place the CE mark 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 10 under the following conditions.

– Surrounding air temperature: 40°C 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 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 10.

 Use the moulded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.

 This product can cause a DC current in the protective earthing conductor. Where a residual current-operated protective

(RCD) or monitoring (RCM) device is used for protection in case of direct or indirect contact, only an RCD or RCM of

Type B is allowed on the supply side of this product.

 Use the inverter under the conditions of overvoltage category II (usable regardless of the earth 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. An insulating transformer needs to be installed in the input side of the FR-A820

series inverters.

– To use the inverter FR-A820-01540(30K) or more and FR-A840-00770(30K) or more (IP00) under the conditions of

pollution degree 2, install it in the enclosure 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 FR-A820-01250(22K) or less and FR-A840-00620(22K) or less (IP20) outside of an enclosure in

the environment of pollution degree 2, fix a fan cover with fan cover fixing screws enclosed.

 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 4 are safely isolated from the main circuit.
