4.5 REAR PANEL J1 PROGRAMMING AND MONITORING CONNECTOR
The J1 Programming and Monitoring connector is a DB25 subminiature connector located on the
power supply rear panel. Refer to Table 4-4 for description of the connector functions. The power
supply default configuration is Local operation which does not require connections to J1. For remote
operation using J1 signals use the plug provided with power supply or equivalent type. It is essential
to use plastic body plug to conform with Safety Agency requirements. If a shield is required for J1
wires, connect the shield to a power supply chassis ground screw.
- J1 connector type: AMP, P/N: 5747461-3
- J1 plug description: AMP, P/N: 745211-7
- Wire dimension range: AWG26-22
- Extraction tool:AMP, 91232-1 or equivalent.
- Manual Pistol grip tool:
Handle:AMP, P/N: 58074-1
Head:AMP, P/N: 58063-2
Before making any connection, turn the AC On/Off switch to the Off position and wait until the front
panel display has turned Off.
4.5.1 Making J1 connections
To prevent ground loops and to maintain the isolation of the
power supply when programming from J1, use an
ungrounded programming source.
CAUTION
The programming return terminals (12, 22 and 23) are
referenced internally to the -V potential of the power supply.
Do not attempt to bias any of these terminals relative to the
-V or any other potential. Use the Isolated Programming
interface option to allow control from a programming source
at a different potential relative to the power supply negative
output.
CAUTION
There is a potential shock hazard at the output when using a
power supply with rated output greater than 40V. Use wires
with minimum insulation rating equivalent to the maximum
output voltage of the power supply.
