INTRODUCTION

The Liebert UPStation S™ Uninterruptible power supply (UPS) system protects valuable equipment, data, and processes from utility power disturbances. The high- performance, on-line, microprocessor-controlled design ensures clean, regulated, sinewave power to loads regardless of utility power fluctuations. An internal battery provides power to loads during utility power outages.

This highly intelligent UPS alerts you to unusual circumstances, or configure the UPS to serve as a source of information and a power control base for specific

applications. Programmable parameters, computer interfaces, and several network control features (remote status/control, Power Management, event logging, and others) provide maximum application flexibility.

Features

∙Input power factor correction (PFC) makes optimal use of utility power.

∙Input current total harmonic distortion (THD) of less than 5% minimizes noise on the branch circuit and reduces neutral currents.

∙Power Output Distribution (unit) facilitates UPS repair or battery replacement without disrupting power to the load on 3.5 - 6 kVA units

∙Temperature-compensated battery recharge for longer battery life.

∙Programmable voltage and frequency.

∙Tower configuration with small footprint.

∙Two-phase pulse width modulated (PWM) inverter with isolated neutral.

∙UL 1778 and CSA 22.2 listed for user safety.

Standard System Components

∙Integral Battery

∙LCD Display for comprehensive user indications and controls

∙Audible Alarm

∙Remote Emergency Power Off (REPO) capability

∙Auto-Restart capability

∙Automatic Bypass

Optional System Components

∙Communication Interfaces: SiteNet 1 Shutdown Kits, SiteNet 2 Power Surveillance, and SiteNet SNMP

∙External battery cabinets

∙Power Management for individual load control.

UNLOADING THE UPS

Refer to the figures below:

1.Remove shipping bands (A) and edge protectors (B).

2.Remove polybag and box.

3.Remove bracket mounting bolts (C) from pallet.

4.Knock out shims (D) with hammer and screwdriver.

5.Thread leveling feet (E) flush with unit bottom.

6.Remove front pallet hex bolts (F). Remove the front skid (G).

7.Slowly tilt the unit forward and roll it off the pallet. CAUTION: The units are heavy. Use at least two people for this step.

Unbolt shipping brackets (H) from unit. Inspect unit. Verify model number and check for damage. Make sure UPS Input, Output, and Battery circuit breakers are Open (OFF).
