Operating The Device - Siemens SIMATIC IPC477E Product Information

Procedure
Note
Reverse-polarity protection
The 24 V DC power supply is protected against polarity reversal. If you mix up the 24 V DC connecting cables and ground, the
device is not damaged but does not switch on. After the power supply has been connected correctly, the device will again be
ready to operate.
Securing cables
Procedure
Use cable ties to secure the connected cables for strain relief:
1. USB cables to vertical fixing elements.
2. LAN cables to special horizontal fixing elements.
3. Remaining cables to the marked fixing elements.
Make sure that the cables are not crushed by the cable tie.

Operating the device

You operate the multi-touch screen with one or multiple fingers. You can also operate it using gestures with up to five fingers
at a time.
WARNING
Personal injury or property damage due to no earth connection or protective conductor connection
An inadequate earth connection/protective conductor connection or the lack of one may cause malfunctions 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 grounding conductor or the protective conductor.
• The grounding conductor from the device must be connected directly to earth with low impedance (short connection,
minimum cross-section 2.5 mm
• The protective conductor connection on the device must be connected to the protective conductor of the control
cabinet or system in which the device is installed using a wire with a minimum cross-section of 2.5 mm
You can find additional information on connecting the grounding conductor in the section "Connecting the 24 V DC power
supply (Page 16)".
