(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive (Standard to
comply with: EN50178).
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
leakage circuit breaker as an electric shock protector without connecting the
equipment to the earth (ground).
* Wire the earth terminal independently. (Do not connect two or more cables to
one terminal.)
* The wire size on pages 18 and 19 are shown for following conditions.

Wire installation:

If conditions are different from above, select appropriate wire according to
EN60204 ANNEX C TABLE 5.
* Use the no-fuse breaker and magnetic contactor which conform to the EN or
IEC Standard.
Design notice: Where residual-current-operated protective device (RCD) is
used for protection in case of direct or indirect contact, only
RCD of Type B is allowed on the supply side of this Electronic
Equipment (EE). Otherwise another protective measure shall
be applied such as separation of the EE from the environment
by double or reinforced insulation or isolation of EE and supply
system by a transformer. (Extract from EN51078)
* Use the inverter under the conditions of overvoltage category II and
contamination level 2 or higher specified in IEC664.
* 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.
* The terminals indicated as the input and output terminals for control circuit on
page 13 are isolated safely from the main circuit.
