2.1 Intended use
The CU8110-0060 UPS is intended for mounting on a DIN rail in an industrial control cabinet or terminal box.
Alternatively, the UPS can be equipped with a mounting plate and mounted on the rear panel of the control
cabinet. The UPS supports in particular Industrial PCs, Embedded PCs, Panels and Panel PCs in case of
voltages fluctuations or failures and this way ensures a safe shutdown of the system.
The UPS has been developed for a working environment that satisfies 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. The specified limits for electrical
and technical data must be adhered to.
The CU8110-0060 UPS is maintenance-free. The energy module (EDLC) does not need to be replaced even
after several decades.
Improper use
The UPS is not suitable for operation in the following areas:
• Potentially explosive atmospheres.
• In areas with an aggressive environment that is enriched, for example, with 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 Staff qualification
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 Industrial PC and the associated network.
All interventions must be carried out with knowledge of control programming, and the qualified personnel

Assembly
• Never work on live equipment. Always switch off the power supply for the device before installation,
troubleshooting or maintenance. Protect the device against unintentional switching on.
• Avoid polarity reversal of the data and supply cables, as this may cause damage to the equipment.
• Observe the relevant accident prevention regulations for your machine (e.g. the BGV A 3, electrical
systems and equipment).
• Note the temperature limit values for operation. If the UPS is operated outside of these temperature
limit values, electrolyte can escape, heat up or in the worst case explode.
• The UPS location must be adequately ventilated. In case of a fault, the UPS can release flammable
gases that could cause an explosion.
• Do not store the UPS in an airtight container or bag. The battery pack can release gases that could
explode if the UPS is kept in an airtight enclosure.
• If you come into contact with electrolyte, rinse the affected body part immediately with water.

CU8110-0060 11Version: 1.0
4 Product overview
UPS-OCT availability
UPS-OCT should be available from Q2 2024 (new hardware required).
The CU8110-0060 is a capacitive uninterruptible power supply (UPS) based on double-layer capacitors
(EDLC) with a maximum energy of 0.3 Wh and a maximum power output of max. 55W.
In the event of a fault or the failure in the 24 V DC input voltage, the UPS takes over the supply of power to
the connected devices with a controlled and buffered 24 V DC output voltage. All Beckhoff components or
components from third parties, especially industrial PCs, embedded PCs, panels and panel PCs, can be
equipped with the CU81xx UPS series. The UPS has a total of two 24-V outputs. In addition to the industrial
PC, a panel or terminal segment can be supplied with uninterrupted power on the second output.
OCT (One Cable Technology), USB 2.0, and digital signals are available for communication between the
UPS and the industrial PC. A special feature of OCT is that the connecting lines (+24 V, 0 V) between the
industrial PC and UPS are used not only to supply power to the industrial PC, but also for bidirectional,
modulated data transmission.

4.3 Block diagram
The block diagram for the CU81xx UPS is described in this chapter. The input voltage Uin typically comes
from a single-phase (230V) or three-phase (400V) AC power supply, the secondary side of which provides
the 24 V DC operating voltage for the UPS. The charging electronics takes the energy for charging the
energy carrier, i.e. the batteries or capacitors, from this input voltage. The charging electronics ensures that
all parameters of the energy carrier (e.g. maximum charge or discharge currents, temperatures, minimum
energy) remain within the permitted limits.
Fig.3: CU81x0-x00x block diagram.
If the input voltage is at least 24V -15% (20.2V), the UPS, which is connected between the AC power
supply and the load to be supported, always supplies at least 24V at the output due to a step-up converter.
If the input voltage drops below this value, operation is switched to UPS mode and the output is supplied by
the energy storage device (UPS mode). The UPS then continues to supply exactly 24V. In the case of an
input voltage from 24V to 24V+20% (28.8V), this is present directly at the output due to the bypass
circuit. If the input voltage exceeds the threshold of 28.8V, a transition to UPS mode takes place in order to
protect the end devices. At the same time, an overvoltage warning is output. Therefore, less than 24V and
more than 28.8V can never be present at the UPS output.
The complete control of the UPS is handled by the central UPS controller, which orchestrates the interaction
of all other microcontrollers (UPS-OCT communication, charge controller).

CU8110-0060 19Version: 1.0
6.1.2 Installing the mounting plate (optional)
In this chapter, we show you how to install a mounting plate on the UPS. With the mounting plate, the UPS
can subsequently be fastened to the rear panel of a control cabinet. To do this, the two DIN rail adapters and
the grounding springs on the rear side of the UPS have to be dismounted. The mounting plate is not included
in the scope of delivery (see: Accessories [}51]).
Requirements:
• C9900-M675 mounting plate made of black anodized aluminum.
• Screwdrivers.
Install the mounting plate as follows:
1. Loosen the six M4 screws and remove the DIN rail adapter.
2. Loosen the M3 screws and remove the grounding springs from the UPS.
3. Fasten the mounting plate to the rear panel of the UPS with four M4 screws.

CU8110-006020 Version: 1.0
6.2 Power supply
An external power supply unit is required for the supply of power to the UPS, which provides a 24V DC
voltage (-15% / +20%). Connect the external power supply unit to the Uin input of the UPS.
Fig.10: Schematic wiring of a CU8110-0060 UPS.
The cabling of the UPS in the control cabinet must be done in accordance with the standard EN
60204-1:2006 PELV = Protective Extra Low Voltage:
• The "PE" and "0 V" conductors of the voltage source for a UPS must be on the same potential
(connected in the control cabinet).
• Standard EN 60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective earth conductor system.
Selecting the appropriate power supply unit
Dimension the power supply unit according to the maximum power consumption of the connected devices
including the current consumption when charging the UPS. For example, if a CX9020 with a power
consumption of 5W (= 0.21A) is connected, the calculation looks as follows: 0.21A + 2.2A = 2.41A. In this
calculation example, at least a 2.41A power supply unit is required for the CX9020.
