4.5 REAR PANEL J1 PROGRAMMING AND MONITORNG 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 descript
ion of the connector functions. The power
supply default configuration is Local operation, which does not require connections to J1. For remote
o
p
eration using J1 signals, use the plug provided with power supply (or equivalent type). It isessential
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.

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
Termi
nals 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 terminals relative to the
negative sense. Use the Isolated Programming interface
option to allow control from a
programming source at a di
f-
ferent potential rel
a
tive to the power supply negative.
CAUTION
To prevent ground loops and to maintain power supply isol
a-
tion when programming from J1, use an ungrounded pr
o-
gramming 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 insula
tion rating equivalent to the maximum
output voltage of the power supply.
