Do not plug or pull connectors in potentially explosive atmospheres
If you plug in or pull out the connector during operation, there is a risk of sparkover. An
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
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.
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)".
Notes on commissioning and operating
Personal injury or property damage due to no earth connection
An inadequate earth connection or the lack of one may cause malfunction of the capacitive
touch screen. Functions may not work properly. This can result in personal injury or
property damage.
• Always connect the device to an earth conductor.
• The earth conductor from the device must be connected directly to earth with low
impedance (short connection, minimum cross-section 4 mm
2
).
Personal injury or property damage due to maloperation
Incorrect operation of devices with a touch screen can occur. This can result in personal
injury or property damage.
Take the following precautions:
• Configure the plant so that safety-related functions are not operated with the touch
screen.
• Switch off the device for cleaning and maintenance.
