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 75°C 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.
Short circuit rating
Suitable for use on a circuit capable of delivering not more than B rms symmetrical amperes, A
volts maximum.
Notes 1) A box (
) in the above table replaces S or E depending on the enclosure.
2) A box (
) in the above table replaces A, C, E, or J depending on the shipping destination.
3) Asterisks (**) in the above table denote the following:
