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 |
| 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
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 |
| Wire Size: | AWG 26 to AWG 22 |
| Extraction tool: | AMP part number |
| Manual pistol grip tool: | Handle: AMP p/n |
|
| Head: AMP p/n |
| Pins 12, 22 and 23 of J1 are connected internally to the negative sense | |
CAUTION | ||
| 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.
