Product overview
CU8130-0120 11Version: 1.0
4 Product overview
The CU8130-0120 is a battery-backed, uninterruptible power supply (UPS) based on NiMH cells with a
maximum energy of 15 Wh and a maximum power output of 110 W.
In the case of a fault or the failure of 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).

6.1.1 Fastening to the DIN rail
For optimal dissipation of heat, mount the UPS horizontally in the control cabinet on a DIN rail. The housing
is designed so that the UPS can be held against the DIN rail and snapped onto it.
Requirements:
• DIN rail of the type TS35x15 2.3 according to EN 60715.
Fasten the UPS to the DIN rail as follows:
1. First, place the UPS against the lower edge of the DIN rail.
2. Tilt the upper part of the UPS towards the DIN rail.
3. Lightly press the UPS against the DIN rail and upwards.
ðAs soon as you press the UPS upwards, the lower springs of the DIN rail adapters give way. In this
manner, the UPS can be attached on the upper edge of the DIN rail.
4. Attach the UPS to the upper edge of the DIN rail.
ðYou have successfully mounted the UPS. Check again that the mounting is correct and that the UPS is
engaged on the DIN rail.

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. Dimension the
power supply unit according to the maximum power consumption of the connected devices. A power supply
with an output current of min. 10 A is recommended.
Fig.10: Schematic wiring of a CU8130-0120 UPS.
Connect the devices to be supported to the U1out and U2out outputs. If the external 24VDC input voltage is
lost, the UPS takes over the supply of the devices connected to it thanks to its regulated and buffered
24VDC output voltage. Use the two 9-pin connectors with push-in connection to wire the CU8130-0120
UPS.
Table8: Required cable cross-sections and strip lengths.
Cable cross-section 0.5 ... 1.5 mm2,
max. 1 mm2 with wire end sleeve

max. AWG 17 with wire end sleeve
Strip length 8 ... 9 mm 0.33 inch
Connect the UPS as follows:
1. Open a spring-loaded terminal by lightly pressing the push mechanism with a screwdriver or a mandrel.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is relieved.
ðIf the DIAG LED is green, the UPS is being supplied with power. If the DIAG LED is red, the input voltage
Uin is not present.
Fuse
When dimensioning the fuse, observe the power consumption of the load to be supported or the maximum
power consumption of the UPS (see: Technical data [}51]). The secondary side is protected by electronic,
5 A.
Grounding
In case of mounting on a DIN rail, the UPS is grounded by grounding springs on its rear side. Ground the
DIN rail in the control cabinet accordingly. A UPS with a mounting plate (optional) is grounded via the
grounding screw.
