1.0 Introduction 1.1 Overview The UPS is a high performance standby uninterruptible power source designed to protect computers and peripheral devices such as monitors, modems, tape drives, etc. from utility line failures which could result in the loss or corruption of valuable data. In the event of a utility failure such as a blackout, brownout, swell or sag, the UPS rapidly transfers loads (computer equipment) to an alternative power source. This alternative power is derived from a battery wi

ENGLISH 2.0 Safety ! ■ To reduce the risk of electric shock, disconnect the Uninterruptible Power Source from the mains before installing a computer interface signal cable (when used). Reconnect the power cord only after all signalling interconnections have been made. ■ Connect the Uninterruptible Power Source to a two-pole, three-wire grounding mains receptacle. The receptacle must be connected to appropriate branch protection (fuse or circuit breaker). Connection to any other type of recep

FRANÇAIS 2.0 Sécurité ! ■ Pour réduire le risque d’électrocution, débranchez la prise principale de la source d’alimentation permanente (Uninterruptible Power Source), avant d’installer le câble d’interface allant à l’ordinateur (si utilisé). Ne rebranchez le bloc d’alimentation qu’après avoir effectué toutes les connections. ■ Branchez la source d’alimentation permanente (UPS) dans une prise de courant à 3 dérivations (deux pôles et la terre). Cette prise doit être munie d’une protection adéq

DEUTSCH 2.0 Sicherheit ! ■ Um die Gefahr eines elektrischen Schlages auf ein Minimum zu reduzieren, die unterbrechungsfreie Stromversorgung vom Stromnetz trennen, bevor ggf. ein Com- puter-Schnittstellensignalkabel angeschlossen wird. Das Netzkabel erst nach Herstellung aller Signalverbindungen wieder einstecken. ■ Die unterbrechungsfreie Stromversorgung an eine geerdete zweipolige Dreiphasen- Netzsteckdose anschließen. Die Steckdose muß mit einem geeigneten Abzweigschutz (Sicherung oder Leist

3.0 Installation 3.1 Receiving inspection Once the UPS has been removed from its shipping container, it should be inspected for damage that may have occurred while in transit. Immediately notify the carrier and place of purchase if any damage is found. Two output jumper cords are provided with the UPS. The packing materials are made from recyclable materials and should be saved for reuse or disposed of properly. 3.2 Placement The UPS may be installed in any protected environment. The locatio

3.0 Installation 3.4 Connecting to the utility The UPS is furnished with two 1.8 meter output power cords for connection to computer equipment having “IEC 320” male appliance couplers at their input. However, due to the variety of plug connectors required for connection to electrical service in countries where the UPS may be operated, an input line cord is not supplied from the factory. In most cases this will not be a problem as the input cord which currently powers your computer equipment may

3.0 Installation 3.6 Connecting your equipment to the UPS To ensure that your computer equipment will be protected during a utility failure and that you receive expected run time, it is important that you determine the total power needs of the equipment you wish to protect with the UPS. The power requirements of your equipment should be less than or equal to the capacity of the UPS. The capacity rating of the UPS, in both Volt-Amperes (VA) and Watts (W), is given in the Specifications section

3.0 Installation 3.6.5 Once all power requirement figures have been converted to VA units and added together, simply determine whether the power requirements of your equipment is less than or equal to the capacity of the UPS. If this is not the case, then it must be decided which equipment should be left unprotected by the UPS. See section 3.8 covering overloads. 3.6.6 An example of how to determine the power requirements of a computer system is given below. Example - labels found at system equ

3.0 Installation 3.6 Connecting your equipment to the UPS - continued 3.6.7 Once you have determined that your equipment and the UPS are compat- ible, plug your equipment into the UPS’s rear panel output receptacles. Note: Do not plug laser printers into this UPS! The power requirements of a typical laser printer are much larger than the requirements of other computer peripherals and may trip the UPS’s rear panel circuit breaker. Plug laser printers into a quality surge suppressor. Remember th

3.0 Installation 3.7 Test for proper operation - continued cord. Observe that your equipment operates normally during both transfer from utility power to UPS power and back again. Repeat this test four or five times to ensure proper operation. See the following section covering Overloads if abnormal operation is encountered. The power I/0 control switches power to your equipment. If you leave your equipment power switches on, the I/0 power control can be used as a master on/ off switch! 3.8

4.0 Principles of operation 4.1 Noise and surge suppression The UPS contains high performance EMI/RFI (Electro-Magnetic and Radio Frequency Interference) noise and surge suppression circuitry to protect your computer equipment. The UPS provides this suppression continuously, whether or not it is turned on. Normally, the UPS suppresses noise and surges without your notice; that is, the UPS doesn’t transfer your load to its internal power source. Instead, the suppression circuitry reduces the a

4.0 Principles of operation 4.2 Load transfer switch The load transfer switch is actually an electro-dynamic relay which serves to rapidly transfer your computer equipment (load) from the utility to the UPS’s alternate power source in the event of a utility failure. When the utility is restored to within safe limits, the switch acts to re-transfer the load to the utility. Except for the user control switches, the transfer switch is the only moving part in the UPS. The time required for the re

4.0 Principles of operation 4.6 Transformer The UPS’s transformer is an electrical component which “steps up” the output voltage of the inverter to the normal utility line voltage. In addition, it serves to isolate the UPS from equipment failures. 4.7 Monitoring and control electronics This block is the “brain” of the UPS. The monitoring and control circuitry detects utility failures such as blackouts, sags and brownouts; synchronizes the inverter’s output frequency and phase to that of the ut

4.0 Principles of operation 4.8 Operation during a utility failure (continued) of the battery (the battery could be charged faster, but wouldn’t last as long). Utility voltage sags are temporary amplitude reductions of the normal line voltage level. Utility voltage sags can be caused by local high power demand equipment such as elevators, air conditioners, shop tools and electric heaters. Brownouts, defined as long lasting utility voltage reductions, are sometimes initiated by the power company

5.0 Controls and indicators 5.1 Power I/0 switch The power I/0 switch controls power to the UPS and its output receptacles. When the switch is on, the UPS operates and your computer equipment will be powered. When the switch is off, the UPS is de-energized and your equipment is unpowered. If your equipment switches are left on, the entire system can be operated by using just the power I/0 switch. Under normal conditions, the lamp within the power I/0 switch illuminates whenever the UPS is switc
