Conformity to UL standards and Canadian standards (cUL certification) 
If installed according to the guidelines given below, inverters marked with UL/cUL are considered as 
compliant with the UL and CSA (cUL certified) standards. 
1.  Solid state motor overload protection (motor protection by electronic thermal overload relay) 
is provided in each model. 
Use function codes F10 to F12 to set the protection level. 
2.  Connect the power supply satisfying the characteristics shown in the table below as an 
input power supply of the inverter. (Short circuit rating) 
3. Use 75qC(167qF) Cu wire only. 
4.  Use Class 1 wire only for control circuits. 
5.  Field wiring connection must be made by a UL Listed and CSA Certified closed-loop 
terminal connector sized for the wire gauge involved. Connector must be fixed using the 
crimp tool specified by the connector manufacturer.
6. Short circuit rating 
  Suitable for use on a circuit capable of delivering not more than 100 kA rms symmetrical 
amperes, 240 volts maximum for Three-phase or Single-phase 230 V input class. 
  Suitable for use on a circuit capable of delivering not more than 100 kA rms symmetrical 
amperes, 480 volts maximum for Three-phase 460 V input class.
