Vertiv Liebert PSA5, Installation And User Manual, Page: 10 / 26

2.4.2 Connecting for Network, Telephone or TV Protection
Protection from electrical surges to your computer network or telephone is provided. Use the
network/telephone surge-protection ports on the rear panel. Connect the “IN” port to the line from the
wall jack and the “OUT” port to your device port. Use of this feature is not required for proper operation of
the UPS.
Surge protection for your cable modem, DSS Receiver, or cable-TV connection is also provided using the
coax surge-protection ports on the rear panel. Connect the “IN” port to the line from the wall jack and the
“OUT” port to your device port. Use of this feature is not required for proper operation of the UPS.
2.4.3 USB Communication Connection
You can connect the PSA5 to a computer via USB allowing unattended, controlled-shutdown of your
computer in case of UPS input power failure. The UPS works with the computer running software built-in
within the Microsoft® Windows® operating system or the Liebert Multilink™ Shutdown software located at
www.VertivCo.com. Use of this feature is not required for proper operation of the UPS. To use this feature,
plug the provided USB cable into USB Type-B port located on the rear panel of the UPS and the other end
into an open USB port on your computer.
2.4.4 USB Charging Ports
The PSA5 has two easily-accessible, front-panel USB Type-A charging ports. These ports charge phones
or other small USB powered devices. The ports provide up to 2.1 A of charge total shared dynamically
between both ports. You may plug devices into these ports at any time during installation and operation.
NOTE: Charging is only available when the UPS is in an On mode.
2.4.5 Connecting AC Input
Ensure that all the loads are first powered off. Connect to an input-power supply/wall outlet that is
properly protected by a circuit breaker in accordance with national and local electrical codes. The input
receptacle must be grounded. See Specifications, for input cord rating.
Once the UPS is plugged into the wall outlet, it begins charging the battery.
NOTE: While every precaution has been taken to ensure that the battery is in good condition, we
recommend allowing the UPS to be plugged into AC input and to charge the battery for at least 12
hours prior to providing full back-up time protection for any utility-power abnormality.
