3.3.3 Use in areas with combustible dust
Observe the following points when operating a device with
combustible dust:
— To prevent loss of type of protection, the housing may not
be opened.
— Only use cable glands which are approved for the type of
protection and correspond to IP rating ≥ IP-6X.
— Avoid hazardous propagating brush discharge.
3.3.4 Operation in temperature class T6
During operation in temperature class T6, when the equipment
is partially or fully depressurized, ensure that there is no
possibility of an explosive atmosphere getting into the
pneumatic system or that any explosive atmosphere is
removed prior to compression by taking suitable action.
When commissioning in temperature class T6, flush the
pneumatic system with 1.4 (+/- 0.1) bar until all traces of any
explosive mixture have been removed (at least 5 minutes).
Ventilate and evacuate the EDP300 fully several times.
3.4 Temperature data
NOTICE
Legibility of the display is guaranteed at an ambient
temperature of -20 … 70 °C. At -20°C and lower, legibility
can become limited. Legibility can be compensated by
adjusting contrast. Contrast adjustment can be made
manually directly on the device.
The display can fail at temperatures below -20°C. Moreover,
functioning of the device is guaranteed up to -40°C.
