Mitsubishi Electric FR-A520-0.4K Instruction Manual page 57

(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive (compliant with Standard DIN
VDE0160).
2) Compliance
We have self-declared our inverters as products compliant to the Low Voltage Directive and place the
CE mark on the inverters.
3) Excerpts from instructions
* In the 400V class inverters, the rated input voltage range is three-phase, 380V to 415V, 50Hz/60Hz.
* Connect the equipment to the earth securely. Do not use an earth (ground) leakage circuit breaker
as an electric shock protector without connecting the equipment to the earth.
* Wire the earth terminal independently. (Do not connect two or more cables to one terminal.)
* The wire size on pages 16 and 19 are shown for following conditions.
•Ambient Temperature:40°C maximum
•Wire installation:On wall without ducts or conduits
If conditions are different from above, select appropriate wire according to EN60204 ANNEX C.
* Use the no-fuse breaker and magnetic contactor that conform to the EN or IEC Standard.
* Use the breaker of type B (breaker that can detect both AC and DC). If not, provide double or
enhanced 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 and contamination level 2 or less set
forth in IEC664.
(a) To meet the overvoltage category II, insert an EN or IEC standard-compliant insulating
transformer or surge suppressor in the input of the inverter.
(b) To meet the contamination level 2, install the inverter in a control box protected against ingress of
water, oil, carbon, dust, etc. (IP54 or higher).
* In 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. (The
relay outputs are basically isolated from the inverter internal circuitry.)
* The terminals indicated as the control circuit input and output terminals on page 12 are isolated
safely from the main circuit.
