2.3.2

Operation with flammable gas

Observe the following points when operating a device with
flammable gases:
— The device must be used in accordance with the
specifications in the relevant certificate.
— Only the design with the "Intrinsic Safety" type of
protection has been approved for operation with natural
gas. The pneumatic outputs must be vented in non-Ex
areas.
— The maximum ambient temperature must not exceed
60 °C (140 °F).
— During operation with flammable gases in type of
protection "Ex n", the device may only be operated with
approved cable glands.
— During operation with flammable gases, the cover cap for
the air outlets can be removed, and the air outlets can be
tubed separately. Both pipes may not be joined in one
pipe.
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.
2.3.3

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 a hazardous atmosphere getting into the
pneumatic system or that any hazardous 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.
