[Skunkworks] Help with UPS NO load Cut Off

I have a su-kum line interactive UPS 600VA which works well on loads like a PC but connecting loads that draw low power it turns off as it does when no load is connected when in backup mode. The devices are low power (less than 8 watts peak) How can i ensure it works okay under the current load. -- Regards, Job Njogu Muriuki, Phone: (+254) - 772333075 | 736333075 Skype: heviejob | Yahoo: heviejob Address: 42665 00100 Nrb
