J1 Connector Connections
WARNING
SHOCK HAZARD There is a potential shock hazard at the J1 connector when
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.
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
CAUTION
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.
