3. Check the supply air to the operating area. Please note:
To filter the inlet air at the air filter, use a G3 or G4 class filter (EN
|
779).
Inlet air must be free of combustible, explosive, aggressive, caustic
|
or corrosive gases, vapours or dusts.
Maximum relative humidity 95% (non-condensing).
|
Inlet and exhaust air separated to prevent an air short circuit.
|
4. The flow rate is checked for each device. Please note:
Required air flow rate: 4000 m³/h.
|
5. Inspect the area around the device. Please note:
The operating area must be dry, clean and free of foreign objects.
|
Foreign objects such as film, plastic bags and pieces of paper may
be sucked in by the fans, putting the device at risk.
The operating area must be free of combustible or explosive
|
substances.
6. Check the temperature and humidity. Please note:
T = –20°C to +50°C
|
At T = +45 °C, the output is automatically reduced in devices with
|
the level of performance 350 kVA.
Maximum relative humidity 95% (non-condensing).
|
The operating area has been checked.
Check the device fan
1. Top of the device: Inspect the connector of the fan set.
