5.4.7
Elevation
Note
†
Elevation shall not exceed 2000 m for compliance to 61010-1.
Equipment elevation is related to the equivalent ambient air pressure:
•
Normal operation: 0 to 1000 m (0 to 3280.8 ft) at 101.3 to 89.8 kPa
•
Extended operation: 1000 to 3000 m
†
(3280.8 to 6561.7 ft) at 89.8 to 69.7 kPa
The extended operation and shipping specifications exceed EN50178.
•
Shipping: 4600 m (15091.8 ft) at 57.2 kPa max
Note
For extended altitude operation, the maximum ambient temperature rating of the equipment should be reduced by 1°C
(3.4 °F) for each additional 410 m (1345 ft) above 1000 m (3280.83 ft). Therefore, an I/O pack rated for 65°C (149 °F) at
1000 m (3280.8 ft) will be rated for 62.6°C (144.7 °F) at 2000 m (6562 ft).
5.4.8
Contaminants
The control equipment withstands the following concentrations of corrosive gases at 50% relative humidity and 40°C (104 °
F):
Note
This meets EN50178 Section A.6.1.4 Table A.2 (m).
