Installation (continued)
2. Charging the battery
The battery charger of the UPS automatically charges the battery
whenever the power cord of the UPS is connected to a normal
utility power.
When the UPS is running for the first time, charge the UPS for
at least six hours to ensure batteries inside are fully charged
before operation.
You may immediately use the UPS without having to wait for the
batteries to be fully charged. However, it is advisable not to do this
as the UPS will have a shorter back-up time than expected if such
action is taken.
3. Connecting the load
Calculate the power consumption of your loads to ensure that an
overload condition will not happen.
Plug the equipment into the output receptacles on the rear
panel of the UPS.
Turn on the equipment connected to the UPS.
Caution: Do not connect a laser printer to the UPS.
4. Connecting the RS-232/DRY CONTACT
Connect the interface signal cable between the RS-232/DRY Contact
port on the rear panel of UPS and COM1 or COM2 of the computer
if necessary.
The DB-9 connector can work as a dry contact or RS-232
communication port depending on the type of cable and software
used. Refer to section 8 of the communication interface for
more information.
