5.2 Power supply (X102)
Fig. 7: Power supply X102.
To supply the CU81x0 UPS, two 9-pin connectors with push-in connection are used. For the 9-pin
connectors, cables with a cross-section of 0.5 mm² to 1.5 mm² or AWG20 to AWG16 are required. With
cable end sleeve max. 1 mm2 or AWG 17 are permissible.

No. Pin Description
1 Uin,
0V,
PE +24 V DC input, power supply for UPS.
2 U1out,
0V,
PE +24 V DC UPS output with UPS-OCT support, interface for the
device being supported.
3 U2out,
0V,
PE +24 V DC UPS output, interface for a second device being
supported e.g. control panel (display).
The U1out and U2out interfaces together must not exceed the maximum output current of the UPS.

4 UPS RDY,
0V,
PE +24 V DC output. This output is switched to 24V when the UPS
charging is above a set threshold (e.g. 80 %).
5 P FAIL,
0V +24 V DC output for power-fail-signal. This output is switched
to 24 V if the power supply fails or if P SHDN is activated. This
output can be connected with the PC_ON input on a Beckhoff
Industrial PC or any PLC input.
6 NC
NC Reserved.
7 UPS EN +24 V DC input. A falling edge from 24 V to 0 V signals the
UPS to switch off the outputs U1out and U2out immediately.
This input can be connected with the PC_STATUS output on a
Beckhoff Industrial PC or any PLC output.
8 P SHDN +24 V DC input. A rising edge from 0V to 24V at this input
triggers an immediate shutdown of the operating system. If
there is 24 V at P_SHDN on startup, the PC will first be started
with a falling edge from 24 V to 0 V.
