■ 220/230/240 Vac versions

The 220/230/240 Vac version UPS is not furnished with an input line cord. Instead, two

output cords are supplied. However, in most installations it will not be necessary to

purchase a UPS input power cord. Simply swap the line cords from your equipment

with the furnished output cords. Plug in the UPS using one of the swapped out

equipment cords. The UPS's input cord must be three conductor, each 1.0 mm

, rated

to 10 Amps.

In the event your equipment does not have a removable line cord, the provided

rewireable plug may be installed on the line cord. Additional output cords and adapter

plugs are available from your dealer and from the factory.

The UPS may be configured to operate where 240 Vac, 50 Hz service is provided. When

Option switch 2 is set to the on position, the UPS's transfer and on-battery output

voltages are adjusted for proper operation on 240 Vac service. See section 5.6.

4.4.2 Enable UPS

Move the UPS Enable switch to the on ( I ) position. When

shipped, this switch is in the off position to prevent accidental

activation of the UPS. The batteries will not appreciably dis-

charge if this switch is left on.

Allow the UPS to charge its battery for at least 8 hours before use. The UPS recharges

its battery whenever the utility voltage is normal and UPS Enable switch is ON. While

the UPS was shipped from the factory with the batteries in a fully charged state, the

batteries may lose some charge during shipping and storage. You may use the UPS

immediately without charging, but the Low Battery indicator may illuminate and the

UPS may have reduced backup time until the battery has had an opportunity to charge.
