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
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).
Corrosive Gas
Sulfur dioxide (SO2)
Hydrogen sulfide (H2S)
Nitrous fumes (NO)
Chlorine (Cl2)
Hydrogen fluoride (HF)
Ammonia (NH3)
Ozone (O3)
5.4.9 Vibration
5.4.9.1 Seismic
Universal Building Code (UBC) - Seismic Code section 2312 Zone 4 (Optional)
5.4.9.2 Operating/Installed at Site
Vibration of 1.0 G Horizontal, 0.5 G Vertical at 15 to 120 Hz
Refer to Seismic UBC for frequencies lower than 15 Hz.
