Emerson GXT2-PP20KRT208 user manual Parallel Communication Port, Optional Power Distribution

Major Components

3.5Parallel Communication Port

The Liebert GXT2-PP20KRT208 parallel POD has three 15-pin parallel communication ports on the upper right of the parallel POD. Several signals are provided on this port to communicate with each UPS. Use the parallel communication cables for the connection between the parallel POD and each UPS. When the UPS is powered on, it enters parallel mode automatically. Refer to 5.0 - Installation for the cable connection procedures

NOTICE

Do not disconnect the parallel communication cable while the parallel system is operating and powering the connected load. This may cause load-drop and damage the UPS or connected equipment.

If the parallel communication cable is disconnected or the connection is dropped during parallel operation, the UPS will shut down immediately.

If the parallel communication cable is not connected to the UPS, the UPS will not enter parallel mode, even if the parallel power cable is connected. Operating without the parallel communication cable may result in damage to the UPS.

3.6Optional Power Distribution

Additional power distribution options are available to provide the benefit of output receptacle conve- nience. See 5.4 - Add an Output Power Distribution Module—Optionalfor installation steps.

NOTE

The Liebert GXT2-PP20KRT208 distribution POD options are different than the distribution PODs used with individual Liebert GXT2-10000RT208 UPSs. Each POD type has different connectors and are not interchangeable.

If a Liebert GXT2-10000RT208 UPS that is to be connected to the parallel POD has a distribution POD option, then the distribution POD must be removed from the UPS to connect the parallel power cable assembly to the UPS.
