explosion can be triggered in the hazardous area due to sparkover, and death or serious
bodily injury can occur.
Plugging or pulling connectors, such as a 24 V DC power supply plug, is prohibited in the
potentially explosive atmosphere.
Only plug or pull a connector when one of the following two conditions is met: The area is
no longer hazardous or the device and its plug-in connections are de-energized.

Also read the enclosed documentation for use in potentially explosive atmospheres and the
information in the section "Certificates and approvals (Page 33)".
