Preparation for Installation

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.
• 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.

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.

Installing the UPS

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.

Connecting for Network or TelephoneProtection

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.

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.

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. 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.

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.

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.

OPERATION

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.

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.

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.

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 batterybacked-up outlets.

NOTE: The surge-only outlets will not have power.

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.

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.
