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 his own expense.

Safety Instructions

Important: Save these instructions.

This manual contains important instructions for Comet EXtreme UPS Models that must be followed during installation, operation and maintenance of the UPS and batteries.

The Comet EXtreme UPS Models that are covered in this manual are listed below.

Tightening torque for all input and output terminal blocks shall be 10.6 - 12.3 in - lbs. (1.2 - 1.4 Nm) for 4.5

and 6 kVA models and 21.8 - 26.1 in - lbs (2.5 - 3 Nm) for 9 and 12 kVA models.

The normal battery voltage for all models is 240 VDC.

The Comet EXtreme server UPS is intended for installation in a temperature controlled indoor area, free of conductive contaminants.

86-153719-00 B00

Safety of persons

A UPS has its own internal power source (the battery). Consequently, the output terminals may be energized even if the UPS is disconnected from the AC-power source.

Dangerous voltage levels are present within the UPS. It should be opened exclusively by qualified service personnel.

The UPS must be properly earthed.

The battery supplied with the UPS contains small amounts of toxic materials. To avoid accidents, the directives listed below must be observed.

◗

Never operate the UPS if the ambient temperature and relative humidity are higher than the levels specified in the documentation.

◗

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.

Product safety

The UPSs connection to the AC-power source must be protected by a circuit breaker that is easily accessible.

The UPS can be disconnected from the AC-power source by opening the circuit breaker.

◗

Never install the UPS near liquids or in an excessively damp environment.

◗

Never let a liquid or foreign body penetrate inside the UPS.

◗

Never block the ventilation grates on the front or back of the UPS.

◗

Never expose the UPS to direct sunlight or a source of heat.

Special precautions

The UPS connection instructions contained in this manual must be followed in the indicated order.

Check that the indications on the rating plate correspond to your AC-power system and to the actual electrical consumption of all the equipment to be connected to the UPS.

If the UPS is positioned flat, check that not more than five modules are stacked on top of each other.

If the UPS must be stored prior to installation, storage must be in a dry place.

The admissible storage temperature range is -40

°

C to +50

°

C.

If the UPS remains de-energized for a long period, we recommend that you energize the UPS for a period of 24 hours, at least once every month.

This charges the battery, thus avoiding possible irreversible damage.

Warning

Batteries can present a risk of electrical shock and/or burn from high short circuit current. Observe proper precautions. Do not open battery packs. There are NO user-servicable parts within. Do not allow anything to touch the battery terminals. Do not pierce battery pack wiring insulation. Do not allow conductive tools or jewelry to touch battery packs or battery terminals.

2.7 Emergency Power Off (EPO)

The end user is responsible for the installation of an emergeny power off function. Installation must be carried out in compliance with local code regulations.

To power down the entire installation via an emergency power off function, the action should perform the following via a single device:

◗

◗

◗ sever the AC input power to the Comet EXtreme remotely trip off the battery circuit breaker on the Comet EXtreme remotely trip off the circuit breaker for the additional battery cabinet(s), if applicable

Battery circuuit breaker shunt trip connection

To accomodate the EPO function, the Comet EXtreme UPS and battery cabinets come equipped with battery circuit breakers with shunt trip mechanisms. By applying 24 Vdc or 24 VAC across the shunt trip coil, the circuit breaker will trip off, thereby disconnecting battery input to the inverter.

◗

◗

◗

Check that the upstream circuit breaker on the low voltage switchboard, the input circuit breaker, and the battery circuit breaker are all in "off" position

◗

Connect the 24Vdc or 24 VAC output of the EPO circuit to the shunt trip coil across terminals 1 and 4

Once the connections are made, reposition the connection cover panel and reset all circuit

This operating mode may be personalized using the "UPS Driver" software (see section 3.5).

It saves battery power when no equipment is connected to the UPS.

The UPS automatically restarts when the AC-power source returns to within tolerances.

Return of AC input power

If, in spite of the return of AC input power, the UPS does not restart, check that the automatic-restart function

(activated by return of AC input power) has not been disabled (see section 3.5).

Forced shutdown

Ten-second interruption in the supply of power to the connected equipment following a system shutdown, even if AC input power returns during the interruption period.

Frequency-regulation rate

The rate at which the UPS frequency is synchronized with that of the AC-power source. Two possible cases:

1. The installation comprises a single UPS. The frequency-regulation rate is set to "Standard".

2. The installation comprises two UPSs connected in series. The AC-power source supplies power to the first UPS which in turn supplies the second UPS.
