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 4-5 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.

-
J1 Connector type: AMP, P/N: 5747461-3
-
J1 plug description: AMP, P/N: 745211-7
-
Wire dimension range: AWG26 - AWG22
-
Extraction tool: AMP, P/N: 91232-1 or equivalent.
-
Manual Pistol grip tool:
Handle: AMP, P/N:58074-1
Head: AMP, P/N:58063-2
Before making any connections, press the AC ON/OFF power switch to the OFF position and wait until the front
panel display has turned OFF.
CAUTION
The programming return terminals (J1-12, -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
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.
