MAJOR COMPONENTS Input L TVSS & EMI / RFI Filters Transfer Switch Battery Charger Battery Output L Inverter N N G G Transient Voltage Surge Suppression (TVSS) & EMI / RFI Filters These UPS components provide surge protection and filter electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize surges or interference present in the utility line and keep the sensitive equipment protected.
WHAT’S INCLUDED The PowerSure PSP is shipped with the following components: • Quick-Start guide • PowerSure family user manual on CD • Warranty card • MultiLink™ software CD • MultiLink serial cable (M3LS9P9S), 10 ft. (3m) • RJ-11 cord, 7 ft. (2.1 m) • USB cable, 6 ft. (1.8m) PowerSure PSP MultiLink software CD USB cable 6 ft. (1.8m) RJ-11 cord 7 ft. (2.1m) 8 MultiLink serial cable (M3LS9P9S) 10 ft.
INSTALLATION 1. Visually inspect the UPS for freight damage. Report damage to the carrier and your local dealer, Liebert representative or the Liebert Worldwide Support Group. 2. Decide where to place the PowerSure PSP. Install the UPS indoors in a controlled environment, where it cannot be accidentally turned off. Place it in an area of unrestricted airflow around the unit, away from water, flammable liquids, gases, corrosives, and conductive contaminants.
5. Connect Phone/Fax/DSL/Internet/Modem devices to data line connectors. Serial port for MultiLink cable connection 6. Press and release the ON/OFF/Alarm Silence button to turn on the UPS. The UPS will beep and the Utility Indicator will illuminate (green). 7. Turn on connected equipment. 8. Communication options (see Communications section for details): Option 1—Serial Communications Serial communications provides parametric data, for example, input voltage and battery voltage. a.
CONTROLS AND INDICATORS ON/OFF/Alarm Silence Button This button controls output power to the connected load and has three functions: • ON • OFF • Alarm Silence ON/OFF/Alarm Silence ON When the UPS is off, pressing and releasing the main ON/ OFF button will start the UPS, and an audible alarm sounds briefly. The UPS is capable of starting on battery (battery start).
Status Indicators: Fault, Utility, Battery There are three (3) status indicators on the front of the UPS (Utility, Battery and Fault), as shown in the diagram below. Each indicator illuminates to specify the status of the UPS (see Troubleshooting section for details). Utility Indicator (Green) The Utility Indicator illuminates green when the UPS is operating and supplying power to connected loads.
Site Wiring Fault Indicator (Red) The Site Wiring Fault Indicator on the rear panel, as shown below, illuminates red when the UPS detects a line-neutral reversal or a poor neutral-ground. (Refer to Troubleshooting Chart if this indicator is illuminated.
MODES OF OPERATION Normal Mode During Normal mode operation, the PowerSure PSP supplies conditioned, computer-grade power to the connected equipment: utility power passes through the EMI/RFI filters and TVSS circuitry and then through the Transfer Switch to the connected equipment. When the UPS is in Normal mode, the Utility Indicator illuminates green. Utility Indicator (Green) The PowerSure PSP continuously monitors the batteries to maintain them in a fully charged state.
Battery Mode The UPS switches to Battery mode in the event of an extreme voltage/ frequency condition or complete utility failure. The battery system supplies power through the Inverter to generate power for the connected equipment. When the UPS is in Battery mode, the Battery Indicator illuminates green and an alarm sounds every 10 seconds. Battery Indicator (Green) When a low battery condition occurs, the Battery Indicator changes to flashing amber and the alarm sounds every half-second.
COMMUNICATIONS DB-9 Connector The UPS has a DB-9 (9 pin female) connector on the rear to allow UPS status communications with a computer system running MultiLink™ software. The DB-9 is capable of supplying serial communication, on battery and low battery signals. MultiLink, Liebert’s UPS monitoring and shutdown software, is shipped with the UPS, along with a 10-ft. (3m) DB-9 cable required for running MultiLink.
Remote Shutdown Via the DB-9 Connector The PowerSure PSP can be shut down remotely by shorting Pins 5 and 6 or via Pins 4 and 5 of the DB-9 connector. Shutdown Via Pins 5 & 6 When Pin 6 is shorted to Pin 5, the UPS output is shut off regardless of what mode the UPS is operating in. The UPS cannot be started as long as the pins are shorted. When the short is removed, the UPS output can be enabled by pressing the ON/OFF/Alarm Silence button.
MAINTENANCE The PowerSure PSP UPS requires very little maintenance. Follow these practices to prevent problems. Cleaning the UPS The following will help ensure trouble-free operation for years: • Vacuum dust from the ventilation intake occasionally. • Wipe the cover periodically with a dry cloth. Maintaining Batteries The batteries are valve-regulated, nonspillable, lead acid and must be kept charged to retain their design life.
Battery Replacement Procedure Replacement requires removing the battery cover plate on the bottom of the UPS. No tools are needed. To replace the batteries: 2. Pull the white tab towards you to remove the battery from the UPS. Pivot battery 90 degrees clockwise as shown below. 1. Remove the battery cover plate on the bottom of the UPS.
