INTRODUCTION AND SYSTEM DESCRIPTION  
Congratulations on your choice of the Liebert 2U POD . The Liebert 2U POD provides main-  
tenance bypass capability as well as power output distribution. The Liebert 2U POD can be  
used on UPSs in the rack mount or tower configuration.  
The Liebert 2U POD provides an isolated path of power for your UPS system for preventive  
maintenance or service.  
System Description  
The 2U POD has two modes of operation: UPS (UPS available) and MAINS (maintenance  
bypass).  
• In UPS mode, the power is routed through the UPS system delivering conditioned power  
to the load, as shown in Figure 1.

Mains  
UPS  
• In MAINS mode, the power is routed around (bypassing) the UPS system (see Figure 2).  
Mains power is supplied directly to the load through the 2U POD.  
CAUTION  
!
Battery back-up and conditioned power are NOT available  
during the MAINS mode of operation.

INSTALLATION ON GXT 2U UPS  
NOTE  
This manual provides instructions for the 2U POD only. Refer to your UPS  
manual for UPS operation and installation instructions.  
1. Unpack the 2U POD carefully, noting the packing method. Retain the box and packing  
material for possible future shipments.  
2. Visually inspect the 2U POD for freight damage. Report damage to the carrier and your  
local dealer or Liebert representative.  
3. Verify that the 2U POD input cord, UPS input cord, and socket for the UPS are the same  
type of configuration.  
4. If you already have a UPS installed, turn off all connected loads and unplug them from  
the UPS. Turn off the UPS and disconnect the input cord.  
5. Attach the two POD securing brackets (this is optional for GXT 2U UPS) to the rear of the  
UPS (see Figure 4). You will need a long M3 Phillips head screwdriver for this procedure  
(the torque is 0.79 Nm, or 7 in-lb). The POD brackets have a hole to allow the screwdriver  
to reach the screw.

6. Next attach the POD to the securing brackets (see Figure 5). The POD can be installed to  
face one of three different directions utilizing the same mounting procedures.  
Figure 5  
Attaching POD to securing brackets  
7. Make sure the 2U POD rotary switch is in the MAINS position. Use the mains input cord  
originally used with the UPS. Plug the mains input cord from the mains input socket to  
the mains wall socket.  
WARNING: The 2U POD is now electrically live. The MAINS lamp (orange) should now  
be illuminated.  
8. Using the cord provided, connect the UPS input power socket to the POD socket labeled  
“CONNECT UPS LINE CORD HERE.”  
WARNING: The UPS system is now electrically live.  
9. Using the cord provided, connect the POD socket labeled “UPS” to one of the output  
sockets on the rear of the UPS.  
10. Plug in all loads to the output distribution sockets, evenly distributing them on the  
2U POD. The 2U POD now powers your equipment in the MAINS mode.  
11. Turn ON the loads and ensure all are up and operating according to specification.  
12. Start the UPS according to its specific user manual.  
13. Verify that the UPS lamp (green) on the 2U POD is illuminated. If so, transfer the rotary  
switch from MAINS to UPS. The load is now being supplied with conditioned power  
through the UPS.  
14. Before any operation or procedure, always verify that both the UPS lamp (green) and the  
MAINS lamp (orange) are illuminated before changing the status of the rotary switch.

RACK MOUNT INSTALLATION  
1. Rack mount installation of the 2U POD is possible with the use of the rack mounting  
brackets (shipped with the POD). See Figure 6.  
2. The rack mount brackets allow you to rack mount the POD in a 19" enclosure (23" to 19"  
rack adapters would have to purchased separately if you are using our 23" Foundation or  
equivalent cabinet).  
3. The POD can be mounted to face one of four directions depending on your application, and  
utilizing the rack mount brackets provided.  
4. Determine the desired position and direction for the POD, face it in that direction, then  
attach the brackets to the POD with the screws provided.  
5. Consult your rack/enclosure manufacturer’s recommendations for specific rack mounting  
hardware that will be required.  
6. The holes on the rack mount bracket are notched for easy installation. Tighten the POD  
securely to the rails and then follow the startup directions for the POD in the previous  
section, Installation on GXT 2U UPS.

INDICATOR LAMPS  
MAINS Indicator Lamp  
This orange lamp is illuminated when mains power is present (see Figure 7). It signals that  
you may transfer the loads to maintenance bypass (MAINS mode) operation via the rotary  
switch. During a mains power outage, this lamp will be off and the UPS will supply battery  
back-up power to the connected loads.  
UPS Indicator Lamp  
This green lamp is illuminated when there is output power available from the UPS (see  
Figure 7). It signals that it is safe to transfer the connected loads from mains power back to  
UPS output power.
