2.3 Use in hazardous areas
Defective pixels in the display
The manufacturing process of modern displays does not currently guarantee that all pixels of
the display are perfect. It is therefore inevitable that the display will contain a small number
of defective pixels. This does not limit the function in any way provided the defective pixels
are not all in one location.
Additional information is available in section "Technical specifications of the IFPs (Page 124)".
2.3
Use in hazardous areas
The following warnings apply to operating a device with Ex approval in hazardous areas.
Explosion Hazard
Do not disconnect while circuit is live unless area is known to be non-hazardous.
Substitution of components may impair suitability for Class I, Division 2 or Zone 2.
Risque d'Explosion
Ne pas déconnecter pendant que le circuit est sous tension, sauf si la zone est non-
dangereuse. Le remplacement de composants peut compromettre leur capacité à satisfaire
à la Classe I, Division 2 ou Zone 2.
Do not plug or pull connectors in potentially explosive atmospheres
If you plug in or pull out the cable connector during operation, you run the risk of a
flashover. An explosion can be triggered in the hazardous area due to sparkover, and death
or serious bodily injury can occur.
Plugging in or unplugging cable connectors, e.g. a 24 V DC power supply connector is not
permitted in the hazardous area.
Do not plug in or unplug a connector until either of the following conditions is met: The
area is no longer hazardous or the device and its plug-in connections are de-energized.
To switch off the device, close all open programs or the current project, and switch off the
power to the device.
Additional information for the PRO devices in UL hazardous.
The devices are open-type and are required to be installed in an enclosure suitable for the
environment and can only be accessed with the use of a tool or key.
Also observe the enclosed documentation for use in potentially explosive atmospheres and
the information in the section "Certificates and approvals (Page 84)".
