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.

3.4ConnectingtotheUtility

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 be swapped with one of the supplied output cords. Hence, the swapped out line cord can be used instead as the input line cord for the UPS. If this is not the case, ask your local dealer or the factory about obtaining an input line cord for your application. Extra output power cords are also available from the factory.

The UPS is compatible with all 220, 230 and 240 Vac mains voltages. During a mains failure, the UPS powers your load at a nominal voltage of 225 Vac.

3.5Batterycharging

The UPS is shipped from the factory with its internal battery in a fully charged state. However, the battery may lose some charge during shipping and storage. The battery
