1. Introduction The product is used as an external power distribution unit in conjunction with UPS systems or large-scale voltage regulators. It allows to manually transfer the connected equipment to utility power via a bypass switch, permitting scheduled maintenance or UPS replacement without power interruption. Combined power distribution feature and the master-controlled design, it provides maintenance bypass function and power saving within a rack mechanism.
Rack Mount/Wall Mount the Unit The module can be mounted to a 19” enclosure or wall. Please follow below chart for rack/wall mount installation.

4. Operation 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.

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.

Transfer to UPS Protection After maintenance service is done, make sure the UPS operation is normal. Then, reconnect UPS to the unit by following Installation Section. Verify the Power LED is lighting. Then transfer the rotary bypass switch from “Bypass” to “Normal”. Now, all connected devices are protected by UPS.
Master/Slave Function Operation After connecting all devices to the unit, press “Master/Slave switch” to enable status ( ). The Slave On LED will light up when connecting load on master output is above 20W. Press “Master/Slave switch” to disable status ( ), the function is disabled and the Slave On LED will be on.
