Only data sensitive equipment such as a computer, monitor and external drive should be plugged into these outlets.
provided in case of a power outage. Power (AC or battery) is not supplied to these outlets when the UPS is switched off. (Do not plug surge protectors or power strips into the battery back up outlets). Caution: Never connect a laser printer or scanner to the backup outlets of UPS with other computer equipment. A laser printer or scanner draws significantly more power when in use than when idle. This may overload the UPS. To Conduct a Self Test Use the self-test to verify both the operation of the UPS and the condition of the battery. In normal utility power, push the On/Off/Test button less than 2 seconds and the UPS performs a self-test function. During the self-test, the UPS operates in back-up mode. Note! During the self-test, the UPS briefly operates on- battery backup power (the on-battery LED comes on). If the UPS passes the self -test, it returns to on-line operation. If the UPS fails the self-test, it immediately returns to on-line operation and lights the replace battery LED. The loads are not affected. Recharge the battery overnight and perform the self- test again. If the replace battery LED is still on, the battery will need to replaced. This should resolve the issue for you. If you need any further assistance on the issue, you can mail me at [email protected] . I'll be glad to help you. Bye.
