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 and has to be discharged at the place of installation (e.g. in
the switch cabinet) in accordance with the climatic conditions.

elements
Resistive loads and Molybdenum Disilicid heating elements:
Heating element data: Load voltage = 140V; load current = 90A
h Determine the max. load voltage actually taken (e.g. 140 V) 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., 8.5.
The power loss (W) is obtained by multiplying this power loss factor by the
load current (e.g. 90A)
IPC type: 709050/82-12-400-150-100/252
Load voltage = 150V
Load current = 100A
Voltage supply to the power section = 400V
