2. Installation 2. Installation 2.1 Installation precautions CAUTION Handle the inverter with care to prevent damage to the plastic components. Do not hold the inverter by the front cover. It may fall off. 2 Install the inverter in a place where it is immune to vibration (5.9 m/s or less). The inverter is under great influence of ambient temperature. Install in a location where temperature is within the permissible range (-10~50 °C). Maximum Surrounding Air Temperature is 50°C.

2. Installation When two or more inverters are installed or a ventilation fan is mounted in inverter panel, the inverters and ventilation fan must be installed in proper positions with extreme care taken to keep the ambient temperature of the inverters below the permissible value. If they are installed in improper positions, the ambient temperature of the inverters will rise and ventilation effect will be reduced. Install the inverter using screws or bolts to insure the inverter is f
