3 Installation
3.3 Ambient conditions
Misuse The instrument is not suitable for use in areas with an explosion hazard (Ex
areas).
Mounting site The installation site should be free from vibration, dust and corrosive media.
Climatic
conditions - Relative humidity: 5...85 % no condensation (3K3 as per EN 60721)
- Max. air inlet temperature 35°C
- Ambient temperature range: 5 ... 40 °C (3K3 as per EN 60721)
- Storage temperature range: -10...70 °C
Power loss Power loss occurs in the form of thermal discharge at the cooling body of the
power converter, at the EMC filter and choke and has to be discharged at the
place of installation (e.g. in the switch cabinet) in accordance with the climatic
conditions.
Example of the
Molybdenum
Disilicide
heating
elements
Resistive loads and Molybdenum Disilicide heating elements:
Heating element data: Load voltage = 110V; load current = 65A
h Determine the max. load voltage actually taken (e.g. 110V) and find the
point intersecting with the curve for the voltage supply in the power section.
The Y axis shows the attendant power loss factor of, e.g., 7.8.
IPC type: 709050/81-12-400-120-070/252
Load voltage = 120V
Load current = 70A
Voltage supply to the power section = 400V
