INSTALLATION AND OPERATION

Inspection
Remove the unit from the shipping package and inspect it for damage that may occur during transportation. Notify the carrier and place of purchase if any damage is found. Shipping package contains:

• Maintenance bypass switch module x 1
• Quick guide x 1
• Mains power cord x 1

Connect to wall outlet:
Plug the input power cord of the unit to the wall outlet.

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. See “UPS Input” and “UPS Output” in section 2 “Parts Identification”

Connect Equipment
Connect all equipment to output of the unit. Please refer to below chart for detailed equipment connection.

OPERATION

Transfer to Maintenance Bypass
Before transferring to maintenance bypass, make sure the utility is normal. 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 service the UPS.

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. Then, transfer the rotary bypass switch from “Bypass” to “Normal”. Now, all connected devices are protected by UPS.

1. INTRODUCTION
This 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 inside a rack mechanism.

Rack Mount/Wall Mount
This module can be installed in a 19” enclosure or wall. Please follow below chart for rack/wall mount installation.

3. INSTALLATION AND OPERATION

Inspection
Remove the unit from the shipping package and inspect it for damage that may occur during transportation. Notify the carrier and place of purchase if any damage is found. The shipping package contains:

• Maintenance bypass switch module x 1
• Quick guide x 1
• Mains power cord x 1
• Screws and mounting ears

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. Power LED will be off while power failure.

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. See “UPS Input” and “UPS Output” in section 2 “Parts Identification”

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.

PLUG COMPUTER INTO MASTER OUTPUT RECEPTACLE

PLUG PERIPHERALS INTO SLAVE OUTPUT RECEPTACLES

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.

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.

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.

Status & Indicator Table

1. Utility is normal.
2. Utility fails but UPS is providing power.| Power LED (Green) on
Utility failure| Power LED (Green) off
