2.1

Intended use

The power supply unit CX2100-0004 is part of a modular control system and is intended for mounting on a
DIN rail. The system is scalable, so that the basic PC modules, power supply units, system modules and
extension modules can be assembled and installed in the control cabinet or terminal box as required.
The power supply unit CX2100-0004 supplies power to the Embedded PCs of the CX2000 series, the
system modules and the extension modules. The Embedded PCs of the CX2000 series are then used
together with Bus Terminals to receive digital and analog signals from sensors and output them to actuators
or forward them to higher-level controllers.
The power supply units CX2100-0004 are 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.
Improper use
The power supply unit is not suitable for operation in the following areas:
• Potentially explosive atmospheres.
• 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.
2.2
