Xantrex Technology XDL 35-5TP Manuale Utente

  

Connections 

The loads should be connected to the positive (red) and negative (black) terminals marked 
OUTPUT 1, OUTPUT 2, or AUXILIARY. 

Remote sense connections to the loads on Outputs 1 or 2, if required, are made from the 
corresponding positive (+) and negative (

−) REMOTE SENSE terminals.  Remote sense 

operation is selected from the keyboard or via a remote control interface (XDL 35-5TP only); the 
REMOTE SENSE lamp is lit when remote sense is selected.  Switching off remote sense returns 
the instrument to local sensing at the output terminals. 

The terminal marked 

 

is connected to the chassis and safety earth ground. 

The front panel AUXILIARY OUTPUT terminals are duplicated on the rear panel with screwless 
terminals marked AUXILIARY OUTPUT. 

The output and sense terminals are duplicated on the rear panel screw-terminal block marked 
Output +, Output 

−, Sense + and Sense − ; these connections are paralleled with their front panel 

equivalents. 

Remote sense operation is selected from the keyboard or via a remote control interface.   When 
the rear panel terminals are used, remote sense should always be selected to ensure that output 
regulation is maintained within specification.
