This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at user's own expense.
To reduce the risk of fire or electric shock, install in a controlled indoor environment free of conductive contaminants.
This equipment is intended only for installations in a RESTRICTED ACCESS LOCATION.
Pour réduire le riske d'inccendie ou d'électrocution, installer dans une enciente intérieure contrôlée en température et humidité et sans contaminants conducteurs.
Ce matériel est destiné seulement pour des installations dans un EMPLACEMENT RESTREINT D'ACCES.
Um die Gefahr von Feuer und elektrischem Schock zu reduzieren, muss das Gerät in einem temperatur - und feuchtigkeitskontrollierten Raum, frei von leitungsfähigen Verunreinigungen, installiert werden. Dieses Gerät ist nur für die Installation an einem Ort mit qeingeschränkter Zugangserlaubnis vorgesehen.
Diese Ausrüstung ist nur für Anlagen in einem EINGESCHRäNKTEN ZUGRIFF STANDORT bestimmti.

Certification Standards - Three Phase UPS
IEC 1004/ANSI C62.41 Standards for Surge Withstand Ability.
FCC Part 15, Subpart J, Class A.
UL/cUL 1778, Standard for Uninterruptible Power Supply Equipment.
NEMA PE 1 - Uninterruptible Power Systems.
NFPA 70 - National Electrical Code.
ISO 9001.
Safety of Persons
The UPS has its own internal power source (the battery). Consequently, the power outlets may be energized even if the UPS is disconnected from the AC power source.
The UPS must be properly grounded.
The battery supplied with the UPS contains small amounts of toxic materials. To avoid accidents, the directives listed below must be observed:
-Never burn the battery (risk of explosion).
-Do not attempt to open the battery (the electrolyte is dangerous for the eyes and skin).
-Comply with all applicable regulations for the disposal of the battery.
-Batteries constitute a danger (electrical shock, burns). The short-circuit current may be very high. Precautions must be taken for all handling: remove watches, rings, bracelets and any other metal objects, use tools with insulated handles.
-Do not lay tools or metal parts on top of batteries.
Product Safety
A protection circuit breaker must be installed upstream and be easily accessible.
The UPS can be disconnected from the AC power source by opening the input circuit breaker.
UPS must be connected to a nearby power source that is easily accessible.
Never block the ventilation grates of the UPS.
The UPS must be installed in a controlled environment.
Special Precautions
The UPS connection instructions and operation described in the manual must be followed in the indicated order.
Check that the indications on the rating plate correspond to your AC powered system and to the actual electrical consumption of all the equipment to be connected to the UPS.
Before and after the installation, if the UPS remains de-energized for a long period, the UPS must be energized for a period of 24 hours, at least once every 3 months (for a normal storage temperature less than 25°C). This charges the battery, thus avoiding possible irreversible damage.

System Description and Specifications
1.0Scope
Provides a general description of the Comet 40-150kVA Uninterruptible Power Systems major components, available options, and system specifications.
1.1General Description
The Comet family consists of compact, high-efficiency Uninterruptible Power Systems which are available in power ratings from 40-150kVA, and are optimized for compatibility with nonlinear computer-type loads. Computer-aided UPS diagnostics and modular construction assure that any required service can be identified and completed rapidly. Remote system monitoring, remote annunciation of UPS performance signals and communication capabilities allow total control of the UPS by its user. See Figures 1-1 and 1-2.
The Comet UPS and its auxiliary equipment are designed for installation in a room where humidity and temperature can be controlled. The recommended and maximum environmental parameters are listed in the Specifications section of this document.

Comet 40-150kVA
Figure 1-3, and 1-4 show single-line diagrams of a typical UPS system installation. During normal operation, utility power (Main Input) is supplied to the UPS Rectifier where it is converted to DC voltage. The Inverter converts the DC voltage from the Rectifier to three-phase regulated AC voltage, which supplies the critical load. During power failure conditions, the Inverter is supplied by the stored energy in the batteries, and the load is powered continuously with no disruption.

Installation and User Manual
1.2Major Components
The following is a description of the cabinets and major components. Refer to Figures 1-5 to 1-8.
UPS Cabinet |
Converts the input AC power to direct current and charges the battery. DC power |
|
is converted back to clean AC power by the inverter for the critical load. Section |
|
3 describes the operation in detail. |
Auxiliary Cabinet |
Performs the voltage conversion for the input AC and/or bypass AC using step- |
|
up and/or step-down transformers. |
Battery Cabinet |
The battery cabinet stores energy for use by the Inverter. The stored energy is |
|
utilized in the event that the AC input power from the utility source fails, or falls |
|
outside of acceptable tolerances. The internal Battery Charger maintains the |
|
charge of the battery system. The DC output voltage of the charger is tempera- |
|
ture regulated to ensure an optimal charge voltage. If a customer supplied battery |
|
system is to be used, an external battery charger may be necessary. |
|
The standard battery system is housed in a separate enclosure. For systems where |
|
additional back-up time is required, up to two (2) additional battery cabinets are |
|
available. |
|
A standard battery cabinet is available in an adjacent configuration or a stand- |
|
alone configuration. Adjacent battery cabinets are attached to the right side of the |
|
UPS using c-brackets provided with the cabinet. Stand-alone battery cabinets |
|
are remote from the UPS. Refer to the battery cabinet installation drawing for |
|
more details. An external battery system can also be supplied by the customer. |
Rectifier |
Converts the AC input voltage from the utility source into a DC voltage, supplying |
|
the Inverter. |
Inverter |
Converts the DC voltage supplied from either the Rectifier or the battery system into |
|
a three-phase AC voltage. An AC output filter is used to achieve a computer-grade |
|
sinewave output voltage waveform, with a total harmonic distortion of less than 2% |
|
under linear-load conditions. |
Static Switch |
Transfers the load between the Inverter output and the bypass AC source without |
|
interrupting the supply of power to the load, allowing the load to continue |
|
operation in the event of a UPS fault. The Static Switch circuit assures that |
|
voltage from the UPS output cannot be fed back to the utility input lines. |
Battery System |
Stores energy for use by the Inverter. The stored energy is utilized in the event |
|
that the AC input power from the utility source fails, or falls outside of acceptable |
|
tolerances. The internal Battery Charger maintains the charge of the battery |
|
system. The DC output voltage of the charger is temperature regulated to ensure |
|
an optimal charge voltage. If a customer supplied battery system is to be used, |
|
an external battery charger may be necessary. |
