Connecting the industrial PC
CAUTION
Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:
• Never connect or disconnect the device cables during a thunderstorm.
• Provide protective earthing for handling the device.
To prepare the industrial PC for operation, it must be connected. The first step is to ground the device. Then
you can connect the cables and the power supply.
The industrial PC is equipped with a 100-240 V
AC
, 50-60 Hz full-range power supply unit.
4.3.1
Grounding of the industrial PC
Potential differences are minimized and electrical currents are diverted to the ground through grounding or
potential equalization of electronic devices. This is to prevent dangerous touch voltages and electromagnetic
interference.
The protection provided by devices maybe impaired, if they are used in a manner not specified by the
manufacturer.
All connected devices must be SELV (Safety Extra Low Voltage)/PELV (Protective Extra Low Voltage).
Protective earth
A protective conductor is included in the industrial PC's IEC socket for connecting the power supply.
Establish the low-resistance protective earth of the industrial PC via the voltage connection, thus avoiding
dangerous touch voltages.
EMC
NOTE
Hardware damage due to electromagnetic interference
Using the industrial PC without functional earthing can lead to hardware damage due to electromagnetic in-
terference.
• Only use the device with functional earth.
Electromagnetic compatibility (EMC) of the industrial PC includes on the one hand not affecting other
devices and equipment by electromagnetic interference and on the other hand not being disturbed by
electrical or electromagnetic effects itself.
For this purpose, the industrial PC must comply with certain protection requirements. The industrial PC has
EMC interference immunity according to EN 61000-6-2. The EMC interference emission of the device meets
the requirements of EN 61000-6-4.
The functional earth is necessary for the EMC of the device. You establish functional earthing via the
grounding connection between the grounding bolt in the connection section on the top of the industrial PC
(see Fig. 16) and the central grounding point of the control cabinet in which the PC is installed. Use either a
wide, flat ground strap or a round conductor with a minimum cross-section of 10 mm
2
for the ground
connection. In the case of a round conductor, also use a cable lug with a ring and place the ring over the
grounding bolt.
