Connect to the Wall Outlet
Plug the input power cord of the unit to the wall outlet. The Power LED will light up when the
mains is normal. The Power LED will be off while power failure.
Connect Equipment
There are three types of output receptacles: Master, Slave, and Uncontrolled.
Master/Slave Output Receptacles
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: Do not connect devices to the slave output receptacles if you want them to continue
running when your computer is off.
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.
Uncontrolled Output Receptacles
Equipment connected to uncontrolled output receptacles will continue running when the unit
is powered on and utility is normal even though Master device is shut down.
After connecting all devices to the unit, press “Function switch” to enable master/slave
function. The Function LED will light up. Press “Function switch” to disable the function and
the Function LED will be off.
