Appropriate Use
The CX1020 device series is a modular control system designed for top-hat rail installation. The system is scalable,
so that the required modules can be assembled and installed in the control cabinet or terminal box as required.
The UPS Modules are designed to supply CX10x0 Embedded PCs and their bus terminals.

Product overview
System overview
UPS module is available in three variations:
CX1100-0900
CX1100-0910
CX1100-0920
The UPS module is used for the uninterruptible power supply of CX CPUs and any connected CX components. In the
event of a failure of the external supply, the module ensures that the application software can save important data, e.
g. on a Compact Flash card, NOVRAM or in a database via the network. During the UPS retention time, the machine
or process can be transferred into a defined state, and the operating system can be shut down. The retention time
can be set via a rotary switch or via software. The use of state of the art capacitors makes this UPS module – unlike
other battery powered techniques – absolutely maintenance-free and offers rapid charging. The module can simply
added to a CX system. Only a 24 V DC supply cable is needed. The 24 V DC output voltage of the UPS is protected
against short circuit and overload. The CX1100-09xx may be retrofitted on site. A DPRAM user interface provides
options for settings and UPS status messages. The functionality of the UPS is therefore independent of the operating
system to be used. No driver software is required. The TwinCAT System Manager recognizes the UPS module
automatically, and the UPS signals are available to the PLC programmer. A controlled 24 V DC power supply unit
with a minimum output current of 4 A is required.

Note
The maximal output current for UPS module CX1100-0900 is 550 mA!
For higher output current make use of the UPS modules (CX1100-0910 / CX1100-0920), with bigger
output current.
The maximal output current is not suitable for the CX1020 Embedded PCs. So it is strongly
recommended to make use of the UPS modules (CX1100-0910 / CX1100-0920), with bigger output
current.

Product overview
CX1100-09xx Connections
The UPS-Modules are supplied with power by 5-pin "Open Pluggable Connector". The other components of the
embedded system are supplied via the PC 104 bus with 24V DC. (-15 % to +20 % tolerance)
Pin assignment "Open Pluggable Connector":
Pin Assignment
5 0 V DC OUT ( UPS output current)
4 24 V DC OUT ( UPS output current)
3 PWR FAIL (digital output)
2 0 V DC IN (UPS incoming power supply)

Product overview
Connection to power supply
For power supply units with K-bus / E-bus connection (CX1100-0002, CX1100-0003 und CX1100-004) the supply is
realized as follows:
Though the power supply CX1100-0001 has no terminal bus interface the module is connected to the upper input
connectors (24V). Older versions of the power supply are labeled with UPS -/+. These input are not used and more
and must not be connected. The figure shows the correct connection.

Product overview
Power-Fail-Signal Connection
The UPS modules can also be used to supply other bus couplers. To use the UPS module with the bus coupler the
power supply has to be connected with the UPS. The power supply for the bus terminals has to be connected
seperaty. This depends on the terminal bus load. The Power-Fail connection should be connected to a digital input
terminal. (see picture below)
In case of power failure the UPS module rises the POWER-FAIL signal. The PLC program reads the input via the
terminal bus and can shutdown the application. In this mode the control of the UPS module is controlled by the torque
switch at the front side of the module.

Warning
Danger of damage to the unit!
During transport in cold conditions, or if the unit is subjected to extreme temperature swings, condensation on and
inside the unit must be avoided.
Prior to operation, the unit must be allowed to slowly adjust to room temperature. Should condensation occur, a delay
time of approximately 12 hours must be allowed before the unit is switched on.
Installation
The devices are designed for installation in control cabinets. You will find installation instructions in the chapter
mechanical mounting.
Shipping and relocation
Despite the robust design of the unit, the components are sensitive to strong vibrations and impacts. During
transport, your computer should therefore be protected from excessive mechanical stress. Therefore, please use the
original packaging.
