Xantrex Technology XDL 35-5TP manual Front Panel Connections, Rear Panel Connections

Connections

Front Panel 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.

Rear Panel Connections

Auxiliary Output Terminals

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

Main Output Terminals (XDL 35-5TP only)

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.

RS232 (XDL 35-5TP only)

9−pin D−connector compatible with addressable RS232 use. The pin connections are shown below:

Pin	Name	Description
1	−	No internal connection
2	TXD	Transmitted data from instrument
3	RXD	Received data to instrument
4	−	No internal connection
5	GND	Signal ground
6	−	No internal connection
7	RXD2	Secondary received data
8	TXD2	Secondary transmitted data
9	GND	Signal ground

Pin 2, 3 and 5 may be used as a conventional RS232 interface with XON/XOFF handshaking. Pins 7, 8 and 9 are additionally used when the instrument is used in addressable RS232 mode. Signal grounds are connected to instrument ground. The RS232 address is set from the keyboard.
