2 INSTALLATION
2.1 What's Included
•USB cable; one 2 m (6.5 ft) long
•Coax cable; one 1 m (3 ft) long (PST5-660MT120and PST5-850MT120 models only)
•Quick Installation Guide
•Safety and Regulatory Guidelines
•Wall-mounting template
The following are available online at www.VertivCo.com:
•PST5 Installer/User Guide (this document)
•Liebert MultiLink™ Shutdown Software
2.2 Unpacking and Inspection
Unpack the UPS and conduct the following checks:
•Inspect the UPS for shipping damage. If any shipping damage is found, report it to the carrier
and your local dealer or your Vertiv representative immediately.
•Check the accessories included in packaging list. If there is any discrepancy, contact your local
dealer or your Vertiv representative immediately.
2.3 Preparation for Installation
2.3.1 Installation Environment
•Install the UPS indoors in a controlled environment, where it cannot be accidentally turned Off.
The installation environment should meet the specifications listed in Specifications table, see
Specifications on page 21.
•Place it in an area of unrestricted air-flow around the unit, away from water, flammable liquids,
gases, corrosives, and conductive contaminants. Avoid direct sunlight.
•The socket outlet should be nearby and easily accessible.
•This UPS is not for use in a computer room as defined in the standard for the Protection of
Electronic Computer/Data Processing EquipmentANSI/NFPA75.
NOTE: Operating the UPS in temperatures above 77°F (25°C) reduces battery life.
2.3.2 Installation Clearances
Maintain at least 4 in. (100 mm) clearance in the front and rear. Do not obstruct the air inlets on the front
panel and rear panel. Blocking the air inlets reduces ventilation and heat dissipation, shortening the
service life of the UPS.
2.4 Installing the UPS
2.4.1 Connecting Loads
The UPS has 4 battery-backed outlets and surge-protected receptacles and 4 surge-protected-only
receptacles. Plug your critical equipment (such as computer, monitors, etc.) into the battery-backed
receptacles and your less-critical equipment (such as printers and other less-often used peripherals) into
the surge-only receptacles. Take note not to exceed the output-load rating of the UPS.
Vertiv | Liebert® PST5™ Installer/User Guide | 11

2.4.2 Connecting for Network or Telephone 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.
2.4.3 Connecting for Television/Cable Protection
NOTE: For PST5-660MT120and PST5-850MT120 models only.
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.
2.4.4 USB Communication Connection
You can connect the PST5 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 side panel of the UPS and the other end
into an open USB port on your computer.
2.4.5 USB Charging Ports
NOTE: For PST5-660MT120and PST5-850MT120 models only.
The PST5 has an easily-accessible, side-panel USB Type-A charging port. This port charges phones or
other small USB powered devices. The port provides up to 2.0A of charge current. You may plug devices
into this port at any time during installation and operation.
2.4.6 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 on page 21, 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.
Vertiv | Liebert® PST5™ Installer/User Guide | 12

3 OPERATION
3.1 Modes of Operation
NOTE: In all of the following modes, including Off mode:
The UPS always provides surge protection and input-breaker protection to the 4 battery backed-up
outlets and the 4 surge-only outlets. The UPS does not need to be On to provide this protection.
The surge-only outlets always have the same voltage level as the UPS input voltage, even when the
UPS is Off. The surge-only outlets are not voltage regulated, battery backed-up, or switched by the
UPS.
3.1.1 Off Mode
The UPS input is plugged into a stable, 120-VAC source, but the battery-backed-up outlets are turned off.
The internal batteries are charging.
NOTE: The surge-only outlets will still have power.
3.1.2 On/Normal Mode
The UPS input is plugged into a stable, 120-VAC source, and the battery-backed-up outlets are turned
on. The internal batteries are charging.
3.1.3 On/Battery Mode
The UPS input is not plugged in, or the voltage source has become extremely low or high and unusable.
The UPS automatically switches to the internal battery to provide normal, usable voltage to the battery-
backed-up outlets.
NOTE: The surge-only outlets will not have power.
3.1.4 Fault Mode
An error or fault condition has occurred. The battery-backed-up outlets are shut off and the internal
batteries are not charging.
NOTE: The surge-only outlets may still have power if the UPS input is plugged in.
3.1.5 Battery Self-test Mode
The UPS enters a cycle of approximately 10 seconds during which it tests the internal battery. The
battery-backed-up outlets are still temporarily powered by the internal battery. Self-test mode occurs at
the following instances:
•At start-up turning the UPS On.
•Automatically every 8 weeks as a self-check.
•Manually by pressing and holding the power button for 3 seconds when the unit is On.

4 MAINTENANCE AND BATTERY REPLACEMENT
4.1 Precautions
Although the PST5 is designed and manufactured to ensure personal safety, improper use can result in
electrical shock or fire. To ensure safety, observe the following precautions:
•Turn off and unplug the UPS before cleaning it.
•Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.
•Never block or insert any objects into the ventilation holes or other openings of the UPS.
•Do not place the UPS power cord where it might be damaged.
4.2 Battery Charging
The batteries are valve-regulated, non-spill-able, lead acid and should be kept charged to attain their
design life. The PST5 charges the batteries continuously when it is connected to the utility input power. If
the PST5 will be stored for a long time, we recommend connecting the UPS to input power for at least
24hours every 4to6months to ensure full recharge of the batteries.
4.3 Battery Replacement
IMPORTANT! Before you proceed, please review the battery safety precautions available at
https://www.vertivco.com/ComplianceRegulatoryInfo.
You may safely replace the internal battery pack. See the Specifications, for the part number of the
replacement battery for your UPS model number.
To replace the battery:
1. Power-off the UPS and disconnect the input power.
2. Turn the UPS upside down.
3. Remove the battery-compartment screw, then slide off the battery-compartment cover, see
Figure 4.1 on the next page.
4. Lift the white tab and pull the battery out, see Figure 4.1 on the next page.
Vertiv | Liebert® PST5™ Installer/User Guide | 19

Figure 4.1 Removing the cover and battery
5. Disconnect the red battery connector, then the black battery connector.
6. Orient the replacement battery in the same way as the removed battery, connect the black
battery connector, then the red battery connector.
NOTE: When connecting the last wire to the battery, there can be a small spark. This is normal.
7. Seat the battery fully into the UPS and replace the compartment cover and screw.
8. Press-and-hold the power button for 3 seconds to initiate the battery self-test and clear any
previous battery fault warning.
9. Properly dispose of the old batteries at an appropriate recycling facility or return them to
Vertiv in the packing material for the new batteries.
