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 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.
3.5 Battery charging
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 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 the position of the power I/0 switch.
