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 connect
supply default configuration is Local operation, which does not require connections to J1. For remote
tion using J1 signals, use the plug provided with power supply (or equivalent type). It is essential
ug to conform to Safety Agency requirements. If a shield is r
wires, connect the shield to a power supply chassis ground screw.

Before making any connection, turn the AC On/Off switch to the Off position a
panel display has turned Off.
The programming return terminals (12, 22 and 23) are re
erenced internally to the
V potential of the power supply. Do
ny of these terminals relative to the
negative sense. Use the Isolated Programming interface
option to allow control from a programming source at a di
ferent potential relative to the power supply negative output.
To prevent ground loops and to maintain power supply isol
when programming from J1, use an ungrounded pr
There is a potential shock hazard at the output when using a
power supply with rated output greater than 4
with minimum insulation rating equivalent to the maximum
output voltage of the power supply.
