SIMATIC IPC277G
88 Operating Instructions, 08/2021, A5E50059956-AA
Operation
upto 85% at 30 °C, no condensation
Gradient ≤ 10℃/h
Storage/transport
upto 90% at 25/55 °C, no condensation
Gradient ≤ 20℃/h
Atmospheric pressure
Operation 1080 to 627 hPa, corresponds to an altitude of -1000
to 3000 m
Storage/transport 1080 to 660 hPa, corresponds to an altitude of -1000
to 3500 m
Multiplication factors for equipment ambient temperature of operation at altitudes up to
3000m, tested in accordance with IEC 61131-2:2017

: Equipment ambient temperature rating at 2000 m.
2
: Atmospheric pressure and air density increases with decreasing altitude. Therefore utilization of
the derating factor for 0 m to 2000 m for altitudes below sea level is considered conservative.
