SECTION 1- OPERATION
1-1INTRODUCTION
The DEFENDER UPS (uninterruptible power system) from DSPM provides an
exceptional level of load protection and monitoring capabilities. The critical load is
provided with conditioned, regulated, battery backed up power at all times. Both the
voltage level and frequency are controlled at all times to the load.
When the input power is lost to the UPS, such as during a power outage, the UPS
automatically draws power from its battery supply. The critical load receives only clean
sine wave power at all times. There are no disturbances or power interruptions on the
output when the UPS transfers to battery operation. Transfers to and from battery
operations are “No Break” transfers. The internal maintenance-free batteries provide a
few minutes to hours (depending upon model) of backup power. Upon restoration of
input power, the UPS automatically resumes normal operation. Also the UPS
immediately begins to recharge the batteries.
The DEFENDER is a dual conversion three phase UPS available in output ratings of 5
to 50 kVA. The UPS is U.L. listed under UL1778 and/or UL924. The UPS is available
with input voltages of 208 and 480 VAC; and output voltages of 120, 208, 480 and 277
VAC (Other voltages available, consult factory). This information is provided on the
nameplate located on the inside of the front door.

1-2 BENEFITS
The DEFENDER is designed to fit the needs for virtually all power conditioning and UPS
applications. It has been specifically designed to power all forms of modern data
processing, communications, process control equipment, lighting and emergency
lighting equipment. The UPS does not require any derating as other UPS products may
when powering 100% electronic loads including switch-mode power supplies.
The DEFENDER protects sensitive electrical equipment, such as computer systems,
telecommunication networks, LANs, multi-user systems and instrumentation systems
from electrical interference. The UPS protects these systems from power problems
associated with poor quality AC power including complete power outages.
Electrical disturbances can come from practically anywhere: from the incoming power
lines and from within a building. Outside electrical disturbances include lightning strikes,
utility switching, brownouts, and accidents. Electrical disturbances from within the
building can be caused by load cycling (elevators, HVAC systems) fault conditions,
welders, and other electrically noisy equipment. Whether the electrical disturbances are
generated outside or from within the facility, the following power problems will occur:
• Complete power outages
• Brown-outs including momentary sags
• Voltage surges
• Transients including common-mode and transverse-
mode noise
• Frequency shifts and fluctuations
Sensitive electrical equipment needs protection from power problems. Without power
protection, users of sensitive equipment may experience:
• Loss of data including data corruption
• Database corruption
• Equipment and component deterioration
• Premature equipment failures
• Unexpected equipment failures
• Missed deadlines, especially during batch processing
• Loss of real-time transaction processing
• Loss of employee productivity

1-3 PRODUCT FEATURES
The following describes the major sub-systems within the DEFENDER UPS.
INPUT AND OUTPUT FILTER – The input filter reduces the input transients and
harmonics on the input line. This helps protect the electronic circuitry of the UPS. The
output filter filters and noise and line spikes from loads.
RECTIFIER/INVERTER
The Rectifier-Inverter system provides controlled sine wave power to the output. The
output voltage and frequency are monitored by the microprocessor and controlled to
provide precision power with changing inputs and outputs to the UPS system.
MICROPROCESSOR DISPLAY
The microprocessor monitors the input and the output to the UPS system and corrects
for any abnormal condition that may occur. This is displayed on the LCD for operator
information.
DIAGNOSTIC TESTS
When you start the UPS, a diagnostic test is automatically executed that checks the
electronics, batteries, and reports the problems on the display.

MAINTENANCE BYPASS SWITCH (MBS) (optional)
The MBS is a two position switch (Auto, and ByPass). The “Auto” position is the
“normal” position and allows full operation of the unit with the load being fed from the
inverter. The “Bypass” (MAN) position allows the load to be fed from the utility with no
power provided to the inverter. The unit must be de-energized (all feeders OFF) before
conducting service or repairs.

Hydrogen Out-gassing Switch (“HOT” Switch) (optional)
The HOT switch option prevents battery charging when a system exhaust fan is not
functioning. This option incorporates the usage of a “sail switch” (Honeywell # S688A
1007 , provided by others) in the exhaust ducting of the facility. Upon exhaust fan
failure, the sail switch will close a contact which will eliminate the battery charging of the
Defender.
Connect the Normally Closed and the Common contacts of the sail switch to the Hot
Switch terminal block (1 & 3) shown in the picture below.
To verify function, ensure that the system has been started up and is fully operational.
With the system battery breaker OPEN, turn off the facility exhaust fan (the sail switch
will return to its “at rest” position). Measure the DC bus voltage at the battery breaker
(the bottom of the breaker, not the top). This voltage should drop to apprx. 220 VDC in
an 18 battery system and to apprx. 120 VDC in a 10 battery system. Turn on the facility
exhaust fan. Measure the DC bus voltage at the battery breaker. The voltage should
rise to apprx. 237 VDC for an 18 battery system and to appx. 132 VDC in a 10 battery
system.

EXTERNAL “WRAP AROUND” BYPASS SWITCH (EMBS) (optional)
The EMBS is a three position switch (Auto, Test and Bypass). The “Auto” position is the
“normal” position and allows full operation of the unit with the load being fed from the
inverter. The “Bypass” position allows the load to be fed from the utility with no power
provided to the inverter. The “Test” position allows power to the Inverter while the load
is being fed from the Utility.

All Circuit Breakers provided by end user, that are connected to the inputs and outputs need to have a Trip
Curve which is at least 10 times the rated current for .3 seconds, this is to prevent the breakers from tripping
during startup of the unit or the loads, attached to the units. Some Manufacturers refer to these breakers as
"High Inrush" breakers.
