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, or sag, the UPS rapidly transfers loads (computer equipment) to an alternative power source. This alternative power is derived from a battery within t

1.4 Test / Alarm Disable switch A dual function Test / Alarm Disable switch (400VA and 600VA models) allows you to check for proper operation by initiating a transfer to on-battery operation. This test ensures that the UPS is not overloaded and will support the system load during an actual power disturbance. By using the Test function throughout the life of the UPS, you can estimate when the UPS's battery should be replaced. During a utility failure, the Alarm Disable portion of the switch ca

2.0 Safety ! Caution! ■ 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 re- ceptacle. The receptacle must be connected to appropriate branch protection (fuse or cir- cuit breaker). Connection to any other type of r

2.0 Sécurité ! Françias Attention! ■ 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 protec

2.0 Sicherheit ! Deutsch V orsicht! ■ Um die Gefahr eines elektrischen Schlages auf ein Minimum zu reduzieren, die unterbrechungsfreie Stromversorgung vom Stromnetz trennen, bevor ggf. ein Computer- 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 od

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 recyclable. Save for reuse or disposed of them properly. 3.2 Placement The UPS may be installed in any protected environment. The location should provide adequate air

ferroresonant type regulating transformers are not recommended. Use of a surge suppressor connected to the output of this UPS may unnecessarily load the UPS when on- battery. This UPS contains high performance surge suppression - additional suppression components are not required and are not recommended. If in doubt, please consult the equipment manufacturer or the factory. 3.4 Connecting to the Utility The UPS is furnished with two 1.8 meter output power cords for connection to computer equi

should be recharged before conducting the following Test for proper operation (section 3.7) and to ensure that the UPS will provide expected run time. The UPS may be used immediately upon receipt, but may not provide expected run time in the event of a utility failure. The battery will recharge to full capacity within 6 hours when the UPS is plugged in and switched on. Once the battery has obtained a full charge, the UPS will maintain the charge as long as the UPS is plugged in, regardless of

capacity of the UPS, don’t worry. The next section describes a test that you can perform to determine whether or not your equipment and the UPS are compatible, even if the computed power requirement of your equipment is 50% greater than the capacity of the UPS! 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, th

Note: Do not plug laser printers into this UPS! The power require- ments 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 that print jobs can be re-queued when the power is restored! 3.7 Test for Proper Operation After the UPS has had a chance to recharge its battery, turn on the UPS’s power I/0 control and switch on your computer equipm

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. Nor- mally, the UPS will continuously filter surges and electrical noise without using the battery charge. The suppression circuitry will reduce the amplitude of these power disturbances to conform to the strict requir

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. The time required for the relay to transfer your load to either power source is much, much faster than that which is required by any modern computer or

4.6 T ransformer 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 utility; detects low battery

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 itself. During the hot season, the utility may choose to reduce the line voltage in order to cope with the huge power requirements of home and commercial use a

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! The lamp within the power I/0 switch illuminates whenever normal voltages are present at the outpu
