Shock
The inverter in its shipping container withstands shock developed when one edge
of the container is dropped six inches while the opposite edge is resting on the
ground, or it is dropped two inches without any physical damage or degradation of
the electrical performance.
Vibration
The inverter in its shipping container, withstands vibration encountered in shipping
without physical damage or degradation of the electrical performance.
Altitude
This inverter is capable of operation at altitudes up to 3,300 feet at an ambient
temperature of up to +50°C (122°F) and 10,000 feet at an ambient temperature of
up to +40°C (104°F).
Ventilation
The inverter should be mounted so that ventilating openings are not blocked and
air entering the cabinet does not exceed 50° C (122°F).
