4.0 Installation
4.5 Connect UPS to service and enable - continued
220/230/240 Vac versions
The 600VA and 900VA 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
2
, rated to 10 Amps.
In the event your equipment does not
have a removable line cord, the pro-
vided 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 2000VA model UPS is furnished
with an input line cord terminated with a "continental" European plug. Where this plug
is improper, one of the supplied plug adapters is used. Where none of the adapters are
appropriate, a three conductor 16 Amp line cord terminated with an IEC 320 C19 coupler
must be purchased - contact you dealer.
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.
4.5.2 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 discharge if this
switch is left on.
Allow the UPS to charge its battery for at least 16 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.
