Low Voltage Directive
We have self-confirmed our inverters as products compliant to the Low Voltage Directive and affix the CE marking on the
inverters.
• Low Voltage Directive: 2014/35/EU
• Conforming standard: EN 61800-5-1:2007
 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
• Ambient temperature: 40°C maximum
If conditions are different from above, select appropriate wire according to EN60204-1, IEC60364-5-52.
• Use a tinned (plating should not include zinc) crimp terminal to connect the earth (ground) 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
• Use the molded case circuit breaker and magnetic contactor which conform to the EN or IEC Standard.
• DC current may flow from the inverter to a protective earth (ground) conductor. When using a residual current device
(RDC) or residual current monitor (RDM), connect a type B RCD or RCM to the power supply side.
• Use the inverter under the conditions of overvoltage category II (usable regardless of the earth (ground) 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.
• On the input and output of the inverter, use cables of the type and size set forth in EN60204-1, IEC60364-5-52.
• The operating capacity of the relay outputs (terminal symbols A1, B1, C1, A2, B2, C2) should be 30VDC, 0.3A. (Relay
output has basic isolation from the inverter internal circuit.)
• Control circuit terminals on

Maximum altitude

For installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.
• Install the inverter at a place where ultraviolet radiation is not applied directly.
 Wiring protection
Class T, Class J, Class CC fuse, or UL 489 Molded Case Circuit Breaker (MCCB) must be provided.
(Use a product which conforms to the EN or IEC Standard.)
