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
Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes.
1. Solid state motor overload protection (motor protection by electronic thermal overload relay)
is provided in each model.
Adjust function codes F10 to F12 and H89 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
Cu wire only.
4. Use Class 1 wire only for control circuits.
Short circuit rating
When protected by class J fuses, suitable for use on a circuit capable of delivering not more
than B rms symmetrical amperes, A volts maximum.
