PowerWalker Maintenance Bypass Switch 19" - Manual (Page 2)

Connect UPS
Connect a power cord from UPS input to UPS input socket on the unit. Use one power cord to
connect UPS output to UPS output socket on the unit.
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.
Switch
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.
