Table 9 Required Cable Cross-Sections And Strip Lengths - Beckhoff CU8110-0060 Manual

Connect 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 CU8110-0060
UPS.

Cable cross-section
Strip length
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.
ð If 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.
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.
