Altitude Derating
Install the bypass in a location that has an altitude of 1000 m (3281 ft) or lower.
Derate the output current by 1% for each 100 m (328 ft) to install the bypass in altitudes between 1000 to 4000 m
(3281 to 13123 ft).
It is not necessary to derate the rated voltage in these conditions:
