Use in hazardous areas
The following warnings apply to operating a device with Ex approval in hazardous areas.
WARNING
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.
WARNING
Do not plug or pull connectors in potentially explosive atmospheres
When you plug or pull the plug-in connector during operation, there is a risk of an arcover.
An explosion can be triggered in the hazardous area due to sparkover, and death or serious
bodily injury can occur.
Pulling or plugging of plug-in connectors, for example, a 24 V DC power supply connector as
well as the memory card is
prohibited
in the hazardous area.
Plug or pull a plug-in connector only when one of the following two requirements 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.
Also read the enclosed documentation for use in potentially explosive atmospheres and the
information in the section "Certificates and approvals (Page 33)".
