The
RSTi-EP remote I/O system is able to operate in height >2000 m (6561.68 ft) above sea
level, with the following limitations:
There is a derating for ambient temperatures while the RSTi-EP Station is in operating
mode. Refer to the following derating table.
Altitude (m, ft) Factor for Temperature Derating
< 2000 m (6561.68 ft) 1
2001 to 3000 m (6564.96 to 9842.52 ft) 0.88
3001 to 4000 m (9845.80 to 13123.36 ft) 0.78
4001 to 5000 m (13126.64 to 16404.20 ft) 0.68
Example:
Height 3000 m (9842.52 ft): maximum operational temperature is 60° C (140 °F) x 0.88 = 52.8°C
(136.76 °F) at maximum 8A .
