*1 The inverter must not be subjected to sudden changes in temperature that will cause condensation to form.
*2 Do not install the inverter in an environment where it may be exposed to cotton waste or moist dust or dirt which will clog the heat sink
in the inverter. If the inverter is to be used in such an environment, install it in the control board of your system or other dustproof
containers.
*3 If you use the inverter in altitude above 3300 ft (1000 m), you should apply a reduction factor of withstand voltage test and an output
current reduction factor as listed below when selecting the inverter properly.
