J1 Connector Connections

 

SHOCK HAZARD There is a potential shock hazard at the J1 connector when

WARNING

 

using a power supply with a rated output greater than 40V. Ensure that the

 

load wiring insulation rating is greater than or equal to the maximum output

 

voltage of the power supply.

 

 

 

External programming and monitoring signal are located on the J1

 

connector. The power supply is shipped with a mating plug that

 

makes it easy for you to make your wire connections. It is essential to

 

use this plastic-body plug to conform to safety agency requirements.

 

If a shield is required for the J1 wires, connect the shield to the

 

ground screw located on the power supply chassis.

 

Refer to the following figure for the pin assignments. A description of

 

the pins is given in chapter 1.

Pins on this side are referenced to the negative sense (-S) terminal.

Pins on this side are isolated from output terminals and are referenced to chassis ground.

 

The mating plug specifications for the J1 connector are as follows:

 

Mating Plug:

AMP part number 745211-2

 

Wire Size:

AWG 26 to AWG 22

 

Extraction tool:

AMP part number 91232-1 or equivalent

 

Manual pistol grip tool:

Handle: AMP p/n 58074-1

 

 

Head: AMP p/n 58063-1

 

Pins 12, 22 and 23 of J1 are connected internally to the negative sense (-S)

potential of the power supply. Do not attempt to bias any of these pins relative

to the negative output terminal. Use an isolated, ungrounded, programming source to prevent ground loops and to maintain the isolation of the power supply when programming from J1.

Chapter 3 describes how to configure the J1 connector when using it to program the output voltage and current.
