A.1.2 Low Voltage Directive
We have self-confirmed our converter units as products compliant to the Low Voltage Directive (conforming standard
EN 61800-5-1) and place the CE mark on the converter unit.
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 11 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 11.
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 converter unit 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, 400 V class only) and
pollution degree 2 or lower specified in IEC60664.
– To use the converter unit under the conditions of pollution degree 2, install it in the enclosure of IP2X or higher.
– To use the converter unit under the conditions of pollution degree 3, install it in the enclosure of IP54 or higher.
On the input and output of the inverter and the converter unit, 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) should be 30 VDC, 0.3 A. (Relay outputs are
basically isolated from the inverter internal circuit and the converter unit.)
Control circuit terminals on page 3 are safely isolated from the main circuit.
