CAUTION
Terminals 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 t o the
negative sense. Use the Isolated Programming interface
option to allow control from a programming source at a dif-
ferent potential rel
a
tive to the power supply negative.
CAUTION
To prevent ground loops and to m aintain power supply isola-
tion when programming from J1, use an ungrounded pro-
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 insulation rating equivalent to the maximum
output voltage of the power supply.
