servicing of batteries.
2. Do not dispose of batteries in a fire. The battery may explode.
3. Do not open and manipulate the battery
4. A battery can present a risk of electrical shock and high short circuit current.
Remove watches, rings or any other metal objects. Use only insulated tools.
5. Install in a protected environment.
6. Always turn off the battery circuit breaker before testing or performing
maintenance on the battery system.
WARNING
It is strongly advised not to open the UPS cabinet as the components have
very high voltages and touching them may be fatal. Only a technician from
DSPM or a DSPM trained technician may service the unit.
The ETERNALIGHT UPS (uninterruptible power system) from DSPM provides an
exceptional level of load protection and monitoring capabilities. The critical load is
provided with conditioned, regulated, computer- grade 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 internal 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 ETERNALIGHT 1 is a dual conversion single phase UPS available in output ratings
of 2 to 80 kVA. The UPS is U.L. listed under UL1778 and/or UL924. The UPS is
available with input voltages of 120, 208, 240 and 277 VAC; and output voltages of 277,
240, 208, and 120 VAC. This information is provided on the nameplate located on the
inside of the front door.
The ETERNALIGHT 1 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 ETERNALIGHT 1 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
The following describes the major sub-systems within the ETERNALIGHT 1 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.
INPUT POWER FACTOR CORRECTION - The ETERNALIGHT 1 UPS system includes
state – of – the – art input power factor correction. This greatly reduces the amount of
current demanded from your building wiring system, yielding a highly efficient “Building
Friendly” UPS System.
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 display for operator
information.
DIAGNOSTIC TESTS
When you start the UPS, a diagnostic test is automatically executed that checks the
electronics, batteries, and reports and problems on the display.
The ETERNALIGHT 1 is designed for installation indoors where it is protected from the
elements. The UPS can be installed in a variety of different environments including
computer rooms, offices, and industrial/process control locations. For the best
performance and reliability, temperature extremes should be avoided.
Listed below are the environmental specifications for the ETERNALIGHT 1 UPS
SYSTEM.
Adequate clearance around the equipment should be provided for service access and
proper equipment cooling. The UPS must be protected from contact with water and
other liquids. If the UPS is installed in a small, enclosed area, provisions for additional
cooling may be necessary.
OPERATING ENVIRONMENT. Provide an operating environment that meets the
following conditions:
o AMBIENT TEMPERATURE 32° to 104°F
0° to 40°C
o OPERATING ALTITUDE 2,286 M (7500 FT)
o NON-OPERATING ALTITUDE up to 3,048 M (10,000 FT)
o RELATIVE HUMIDITY 0% to 95% (non-condensing)
Operating the UPS and batteries at either extreme of the temperature range may affect
the long-term reliability of the system. This is especially true of the sealed,
maintenance-free batteries. Sealed, maintenance-free batteries are designed to operate
at normal room temperatures (72 to 77° F)
! WARNING ! BATTERY SHELF LIFE !
• BATTERY SHELF LIFE, WHEN STORED UNDER TEMERATURE CONDITIONS of
66° F ~ 77° F, is FOUR (4) MONTHS MAXIMUM AFTER THE SHIP DATE.
• BATTERY MUST BE RECHARGED FOR EIGHT HOURS AFTER THIS DATE
OTHERWISE THEY MAY BE DAMAGED.
The ETERNALIGHT 1 UPS system is shipped on a pallet with the batteries outside
the UPS. This Manual, battery jumper wires and accessories may be included within
the packaging, ensure that these are not discarded with the packaging. Unwrap the
UPS and carefully inspect the external surfaces for abrasions, indentations, or other
obvious damage.
File a claim with the shipping agency for any damage caused by shipping. Forward a
copy of the damage claim to DSPM.
Mount the UPS system so each side and the top has six inches of clearance for
airflow. Leave appropriate space in the front so the front door can be opened fully for
operation and installation.
3-1 INSTALLATION EQUIPMENT
The following instructions cover general requirements for standard installation of the
input and output power circuits, battery connections and control interface
connections. Install the UPS using the procedures in this section. Care must be
taken to insure the unit is properly connected. Connections should be torque as
shown in Table 2-1
THE UPS CONTAINS POTENTIALLY LETHAL VOLTAGES INSIDE, EVEN IF
THE UNIT IS NOT CONNECTED TO AN EXTERNAL SOURCE OF POWER.
ALL INSTALLATION AND SERVICE PROCEDURES SHOULD BE
PERFORMED BY QUALIFIED PERSONNEL ONLY.
The input power circuit is supplied by the customer. This provides power from the
building source to the UPS system. This circuit should be a dedicated branch circuit that
is hard wired in conduit. Size the branch circuit feeder conductors according to the
specific power rating of the unit. Refer to the latest edition of National Electric Code
(NEC) for the exact wire size required.
An insulated grounding conductor must be installed as part of the input circuit. Size the
grounding conductor in accordance with NEC and local codes. The manufacturer
recommends a parity-sized ground, with respect to the input power wires.
3-1 INSTALLATION OF EQUIPMENT (continued)
The UPS is designed to provide superior isolation and protection for sensitive loads.
The UPS can be wired as a separately derived source that allows the re-establishing of
the ground reference at the output of the UPS. This method of installation will provide
additional load isolation from noise and other disturbances.

FOLLOW THE BATTERY SAFETY PROCEDURE IN THE FRONT OF THIS MANUAL.
The UPS system has fixed battery trays. All battery systems connect the batteries in
series, i.e. plus terminal to minus terminal from one battery to another battery. The
battery circuit breaker must be off during the installation. Install the batteries and
connect the battery cables. Connect the minus (-) terminal of the battery group to the
battery circuit breaker terminal that is labeled (-). Connect the positive (+) terminal of the
battery group to the battery circuit breaker terminal that is labeled (+). (Follow Battery
diagram in the unit for installation.)
3. Use a meter and note the D.C. voltage at the battery circuit breaker. The voltage
must be the correct polarity positive lead of the meter to the positive terminal of
the circuit breaker.
4. The D.C. voltage should read between 220 to 240 VDC for an 18-battery unit and
118 to 130 for a 10-battery unit. If the D.C voltage reads below 210 volts D.C., or
115 volts DC, this means the battery cables are not connected correctly.
5. If the battery polarity and voltage level are correct, continue to “Starting the
UPS”.
The History Log is used to record certain events that reflect the status and operating
mode of the unit.
There are 64 lines (00 through 63).
It is read by holding down the Alarm Scan button. Each time the button is pressed, the
log is read sequentially with the most recent event being displayed first. After 00 is
