2.1 Intended use
The CX51x0 Embedded PC is a control system and is intended for mounting on a DIN rail in a control
cabinet or terminal box. The Embedded PC series is used in conjunction with Bus Terminals for recording
digital or analog signals from sensors and transferring them to actuators or higher-level controllers.
The Embedded PC is designed for a working environment that meets the requirements of protection class
IP20. This involves finger protection and protection against solid foreign objects up to 12.5 mm, but not
protection against water. Operation of the devices in wet and dusty environments is not permitted, unless
specified otherwise. The specified limits for electrical and technical data must be adhered to.
Potentially explosive atmospheres
Device modification CX2900-0107 is mandatory for operation of the Embedded PC in potentially explosive
atmospheres, zone 2/22. The device modification includes a factory-installed retainer bracket for
mechanically securing the plug connectors.
The device modification is mandatory for operating the Embedded PC in the following potentially explosive
atmospheres:
1. For Zone 2 atmospheres in which gas is present as a combustible material. Zone 2 means that an explosive atmosphere does usually not occur during normal operation, or only for a short time.
2. For Zone 22 atmospheres in which dust is present as a combustible material. Zone 22 means that an
explosive atmosphere in the form of a cloud does usually not occur during normal operation, or only
for a short time.
The Embedded PC must be installed in a housing, which ensures protection class IP 54 for gas according to
EN 60079-15. A housing with protection class IP 54 is required for non-conductive dust. IP 6X is required for
conductive dust according to EN 60079-31.
Improper use
The Embedded PC is not suitable for operation in the following areas:
• In potentially explosive atmospheres, the Embedded PC may not be used in other zones except for
2/22 and not without a suitable housing.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• Living areas. In living areas, the relevant standards and guidelines for interference emissions must be
adhered to, and the devices must be installed in housings or control boxes with suitable attenuation of
shielding.

All operations involving Beckhoff software and hardware may only be carried out by qualified personnel with
knowledge of control and automation engineering. The qualified personnel must have knowledge of the
administration of the Embedded PC and the associated network.
All interventions must be carried out with knowledge of control programming, and the qualified personnel
must be familiar with the current standards and guidelines for the automation environment.
2.3 Safety instructions
The following safety instructions must be followed during installation and working with networks and the
software.
Explosion protection
Device modification CX2900-0107 is mandatory for operation of the Embedded PC in potentially explosive
atmospheres, zone 2/22. The device modification entails the modification and relocation of the device label
and a factory-fitted retainer bracket for mechanically securing the connectors.
WARNING
Operation without device modification
Without the CX2900-0107 device modification, the USB plug connectors may slip out of the
USB ports due to vibration, which may trigger a deflagration or explosion.
The Embedded PC must only be used with the device modification, and the USB plug connectors must be secured to the retainer brackets with cable ties.
Tighten the screws of the DVI plug connector and, if present, also the screws of the fieldbus plug connectors,
in order to prevent the plug connectors slipping out. Only use RJ45 connectors with an intact latch. Use
cable ties to secure the USB plug connectors and RJ45 connectors to the retainer brackets.
The CXxxxx-N020 optional interface (audio interface) may not be used in potentially explosive atmospheres.
The Embedded PC must be installed in a housing, which ensures protection class IP54 for gas according to
EN 60079-15. A housing with protection class IP54 is required for non-conductive dust. IP6X is required for
conductive dust according to EN 60079-31.
Observe the temperature at the cable entry points into the housing. If the temperature during nominal
operation is higher than 70 °C at the entry points or higher than 80 °C at the wire branching points, cables
must be selected that are designed for these high temperatures and operation in potentially explosive
atmospheres.
Maintain the prescribed ambient temperature during operation. The permissible ambient temperature lies
within the range from 0 °C ... +60 °C.
Take measures to prevent the rated operating voltage exceeding 119 V through short-term interference
voltages.
Switch off the power supply and ensure that no explosive atmosphere occurs when:
• Bus Terminals are connected or removed,
• the Embedded PC is wired or cables are connected,
• the front flap is opened,
• the CFast card, MicroSD card or battery is replaced.

Product overview
CX51x0 17Version: 1.9
The interfaces (USB, DVI, and LAN) are standard interfaces. Devices that meet the corresponding standard
can be connected to and operated at these interfaces. A VGA monitor can be connected to the DVI-I
interface with an adapter.
Intel® i210 Gigabit Ethernet controllers are used as network controllers. There are two independent Ethernet
interfaces. Both LAN interfaces are gigabit-capable.
