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

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).
