Shock
The battery charger 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 battery charger in its shipping contained, withstands vibration encountered in
shipping without physical damage or degradation of the electrical performance.
Altitude
This battery charger is capable of operation at altitudes up to 10,000 feet at an
ambient temperature of up to +40 degrees C.
Ventilation
The unit should be mounted so that ventilating openings are not blocked and air
entering the cabinet does not exceed 50 degrees C (122 degrees F).
