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 a plastic body plug to conform
to Safety Agency requirements. If a shield is required for the J1 wires, connect the shield to
a power supply chassis ground screw.
4.5.1. Making J1 Connections
J1 Connector type: AMP, P/N:5747461-3
J1 plug description: AMP, P/N:749809-9 or equivalent.
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.
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 negative sense. 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
To prevent ground loops and to maintain power supply isolation when
programming from J1, use an ungrounded programming source.
WARNING
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.
