For extended life, prevent dust and other contaminants from entering the
inverter.
When installing the unit inside a sealed enclosure, make sure the enclosure is
sized correctly for proper heat dissipation or that a cooling system has been
installed in the panel.
Protect the inverter against conductive and corrosive gases,
liquids and other contaminants. Water or mist should not be allowed
into the inverter.
The F5 elevator drive must be installed in an explosion-proof enclosure
when operating in an explosion-proof environment.
Maximum Surrounding Air Temperature 45°C! The operating temperature
range of the unit is -10°C to + 45°C (14°F to +113°F). Operation outside of
this temperature range can lead to shutdown of the inverter.
The unit can be stored (power off) in the temperature range of -25°C to 70°C
(-13°F to +158°F).
The power rating of the inverter must be derated for operation above 3,300 ft
(1000 m). Reduce the rated power by 1% for each additional 330 ft (100 m).
The maximum elevation for operation is 6,560 ft (2000 m).
The relative humidity shall be limited to 95% without condensation.
