SED2 VFD Operation & Maintenance Manual
6 Siemens Building Technologies, Inc.
Environmental Conditions
Temperature:
Maximum operating temperature: +104°F (+40°C) *
Minimum operating temperature: +14°F (-10°C)
* Be aware of the potential increase in temperature inside a control cabinet (derating is
required).
Humidity: Maximum 95% rh noncondensing
Height Above Sea Level: If installing the SED2 at an altitude of higher than 3280 ft
(1000 m), derating is required.
Overheating/Ventilation: Install the SED2 vertically for optimum ventilation. Do not obstruct
the SED2 vents. Additional ventilation may be required if the drive is mounted horizontally.
If installing SED2 drives one above the other, the necessary clearance varies according to
the size and protection standard of the drives. See the Mounting section in this manual for
clearance data.
Electromagnetic Radiation: Do not install the SED2 near powerful sources of
electromagnetic radiation.
Atmospheric Pollution: Do not install the SED2 in an environment with atmospheric
pollutants such as dust and corrosive gases. SED2 drives (IP20) need additional protection
from dust, atmospheric pollutants, and water.
Shock: Do not install the SED2 in a location that is exposed to repeated shock or vibration.
