Connect Equipment
There are two types of output receptacles: Master, and Slave.
To save power consumption, the unit is equipped with Master and Slave output receptacles. The
Master output receptacle will sense if master device (computer) is on. If the master device is no
longer drawing current, it will automatically shut down the power to the Slave output
receptacles. Please refer to below charts for detailed equipment connection.
NOTE: When the computer is turned off, the Master output receptacle shuts off power to the
slave output receptacles. However, when the computer goes into “sleep mode” or the power
consumption of connected device to Master output receptacle is below 20 W, the Master output
receptacle may not properly recognize the reduced power level.
Connect Modem/Phone Port for Surge Protection
Connect a single modem/phone line into surge-protected “IN” outlet on the unit. Connect from
“OUT” outlet to the computer with phone line cable.

Transfer to Maintenance Bypass
Before transferring to maintenance bypass, make sure the Power LED is lighting. Transfer the
rotary bypass switch from “Normal” to “Bypass”. At this time, all connected devices are powered
by the utility power directly. You may turn off the UPS and disconnect two cables connecting to
UPS. Then you may now service the UPS.
Transfer to UPS Protection
After maintenance service is done, reconnect UPS to the unit by following Installation Section.
Verify the Power LED is lighting. Then transfer the rotary bypass switch from “Bypass” to
