Tripp-lite PDUB151U Bypass Switch Module
Introduction
This product is used as an external power distribution unit in conjunction with UPS systems. It enables the user to manually transfer the connected equipment to utility power via a bypass switch, permitting scheduled maintenance or UPS replacement without interruption of connected equipment. The optional ECO Switching feature enables power savings by automatically powering off Controllable Output Receptacle Group outlets when the device connected to the master outlet is powered off or goes into a low-power consumption mode.
Rack Mount or Wall Mount the Unit
The module can be mounted to a 19-inch enclosure or wall. Follow Figure 1 for
rack mounting or Figure 2 for wall mounting.

Installation
Inspection
Remove the unit from the shipping package and inspect it for damage that may have occurred during transport. Notify the carrier and your dealer if any damage is found.
Connect to the Wall Outlet
Plug the Bypass PDU main input cord to an unprotected AC outlet. This
connection is labeled MAIN INPUT on the PDU. The MAIN POWER LED will
illuminate when mains input is available. Note: For models PDUBHV101U and
PDUBHV201U, you may need to use your UPS system’s power cable to connect the
Bypass PDU to the AC power source.
Connect UPS
- Connect the UPS input cord to the outlet for UPS input power cord (4). This outlet is labeled “To UPS Input” on the Bypass PDU.
- Connect the protected UPS input power connection on the Bypass PDU to a protected UPS outlet. This connection is labeled “To UPS Output” on the bypass PDU.
- Note: For models PDUBHV101U and PDUBHV201U, use the supplied power cords to make these connections.
Connect Equipment
There are two types of outputs: Master and Controllable Group receptacles. Outlet functions are controlled by the ECO load control switch. When this switch is set to DISABLE, all outlets will operate in an always-on capacity. In this configuration, protected equipment can be connected to any outlet whether it is part of the Master or Controllable Group set of outlets for always-on operation during both Normal and Bypass Modes. When the ECO load control switch is set to ENABLE, the device connected to the load-sensing Master outlet will offer automatic power OFF/ON control of the set of Controllable Group outlets. In this configuration, powering off the device connected to the Master outlet will automatically power off the devices connected to the Controllable Group outlets. Anytime the Master outlet current is measured to be 20W or less, the Controllable Group outlets will power off within 1 second.
Plug Computer into Controllable Output Receptacle
Plug Peripherals into Controllable Output Receptacle Group
Normal/Bypass Mode Operation
Before transferring to maintenance bypass, make sure the Main Power LED is illuminated. Transfer the rotary bypass switch from NORMAL to BYPASS. At this time, the Bypass Mode LED will illuminate and all connected devices will be powered by utility power directly. You may turn off the UPS and disconnect two cables connecting to the UPS. You may now service or replace the UPS.
Transfer to UPS Protection
After maintenance service is complete, ensure the UPS operation is normal. Reconnect the UPS to the unit by following the steps in section 4. Installation. Verify the Main Power LED is illuminated. Then transfer the rotary bypass switch from BYPASS to NORMAL. All connected devices are now protected by the UPS.
ECO Mode Function Operation
After connecting all devices to the unit, press the ECO Mode function switch to ENABLE status ( ). The Controllable Receptacle Group LED will illuminate when the connected load on the master output is above 20W. Press the ECO Mode function switch to DISABLE status ( ) to disable the function. The Controllable Receptacle Group LED will be illuminated.
