(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
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage Directive and place the
CE mark on the inverters.
3) Outline of 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 (ground) securely. Do not use an earth (ground) leakage circuit
breaker as an electric shock protector without connecting the equipment to the earth (ground).
* Wire the earth (ground) 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 (104°F) maximum
•Wire installation:
If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5.
* Use the moulded case circuit 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 lower
specified 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.)
* Control circuit terminals on page 12 are safely isolated from the main circuit.
