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 re-
lay) 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 in-
put power supply of the inverter.(Short circuit rating)
3. Use 75C 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 termi-
nal connector sized for the wire gauge involved. Connector must be fixed using the crimp
tool specified by the connector manufacturer.
Short circuit rating
Suitable for use on a circuit capable of delivering not more than B rms symmetrical amperes,
A volts maximum.
