installation, operation, and preventive
maintenance of the Uninterruptible Power
System (UPS) and Battery Cabinet. Illustrations
showing the function of all operator controls,
instruments, alarms and indicating lights are
also given. Performance specifications at which
the UPS will operate are given in SECTION 6
-SPECIFICATIONS. Please note that some
information is kVA specific.
The Liebert Series 300UPS is available in ten
power ratings - 10, 15, 20, 30, 40, 50, 65, 75,
100, and 125 kVA. Specifications for each model
appear in SECTION 6 -SPECIFICATIONS.

1.1 DEFINITIONS
These d&nitions describe terms as they relate
specifically to series 300 installation, operation
or maintenance. Rather than being
alphabetized, they are presented in an order
most appropriate to understanding the UPS.
Uninterruptible Power System (UPS)
All components within UPS Module Cabinet
and separate Battery Cabinet which
function as a system tc provide ccntinuous,
conditioned AC power to a load.
UPS Module
Bectiiier/Chsrger and Inverter unit which,
under supervision of the Internal Control
System and Operator Controls, provides
specified AC power to a critical load.
UPS Module Cabinet
Metal enclosure containing rectitIer/charger,
inverter, static transfer switch, static bypass
line, maintcnsace bypass line, external
operator controls, and internal control
system required to provide spedfied AC
power tc a load.
Battery Cabinet

Cabinet containing sealed battery cells
sufficient to maintain UPS output according
to speciiications in SECTION 6 -
SPECIFICATIONS.
Input Power
Power provided by the electrical utility
company (or auxiliary generator) and
connected to the UPS input.
Input Filter
Reduces recti&r input current distortion to
10% THD at full load. This Slter also
improves the input power factor,
Input Isolation Transformer
A delta-to-n-ye isolation transformer for the
UPS module input. Provides common mode
noise attenuation for all system operating
modes including while on bypass. Also
provides single-point ground for the system.
Input Auto Transformer
A delta-to-wye auto transformer for the UPS
module input. Enables UPS module to be
installed with external maintenance bypass
cabinet without requiring a transformer in
the external maintenance bypass line.
Rectifier/Charger
UPS component containing equipment and
controls for converting input AC power to
regulated DC power required for battery
charging and for supplying power to the
invertm.
Inverter
UPS component containing equipment and
controls for converting DC power from
BectifierlCharger or battery to regulated AC
power required by the critical load.
Internal Control System
Signal processing circuits which regulate
power conversion processes, detect fault
conditions and control the UPS operating
sequence.
Operator Controls and Display
Rotary switch, selection pads, and digital
display used by operators to monitor and
control the UPS. See SECTION 3 -
OPERATION of this manual.
Static Bypass Line
Line conducting unconditioned input power
to critical load through Static Transfer
Switch. Transfer of load between this line
and the UPS inverter output occurs under
supervision of the Internal Control System.
Static Transfer Switch
Device transferring the critical load between
UPS inverter output and Static Bypass Line.
Transfer
The critical load is transferred from the UPS
inverter output to the Static Bypass Line.
Retransfer
The critical load is automatically
retransferred from the Static Bypass Line
back to the UPS inverter output.

0
Maintenance Bypass Line
Line conducting electricity directly from
input power to critical load during
maintenance or whenever UPS is not
completely operational. Maintenance Bypass
Line is connected when rotary switch is in
Position 1, 2, or 3.
External Maintenance Bypass Cabinet
An external maintenance bypass line in a
matching cabinet with switching
mechanism, and optional circuit breakers
and optional bypass transformer, to totally
isolate the UPS module from the electrical
system.
Slim-Line Distribution Cabinet
A cabinet extension of the UPS module to
enclose one or two 42-pole panelboards, with
a main circuit breaker for each panelboard.
1.2 MODES OF OPERATION
The UPS provides the following three power
paths between the utility source and the critical
load.
l Through the UPS Module
l Static Bypass Line
. Maintenance Bypass Line.
1.2.1 Through the UPS Module
During normal operation, the output of the UPS
Module inverter is used. Input AC power to the
UPS is converted to DC by the rectifier/charger.
The DC power charges the UPS battery and
provides input power for the inverter. The
inverter converts the DC power to conditioned
AC power which supplies the critical load. The
conversion-inversion process eliminates voltage
transients existing in the input power before it
reaches the critical load. If input power is
interrupted, the battery will immediately supply
the DC power required by the inverter to
maintain continuous AC power to the load. A
fully charged battery will provide power for the
specified time at the rated load, or longer at a
reduced load.
1.2.2 Static Bypass Line
The Static Bypass Line provides an alternate
power path during an overload condition or UPS
fault. If the load demands more power than the
inverter can supply (an overload condition), the
control system automatically energizes the
static transfer switch to transfer the load from
the UPS Module to the Static Bypass Line. If
the internal control system detects a fault in the
UPS Module while it is supporting the load, the
static transfer switch transfers the load without
interruption to the Static Bypass Line, thereby
maintaining continuous power to the critical
load.
1.2.3 Maintenance Bypass Line
The Maintenance Bypass Line is a hard-
wired line through the UPS which supplies the
critical load with unconditioned power when the
Rotary Switch is in Position 1, 2, or 3. The
purpose of this line is to route power to the
critical load during start-up or while the UPS
Module is de-energized for maintenance. The
Maintenance Bypass Line can only be selected
manually, using the Rotary Switch. When the
Rotary Switch is in Position 4, the internal
control system determines which of the other
two paths supplies power to the load.
