Output Terminal Insulation
Cautions when using the external voltage (Vext)
Connect the cables so that output is not shorted. See the following figures for examples of
shorted output.
A connection in which the output is shorted by the grounding of Vext (example of a prohib-
ited connection)
A connection in which the output is shorted by the shield (example of a prohibited connec-
tion)
CAUTION
The signal cable may burn out.
• Do not ground the Vext output, that is, leave it floating.
• If you are connecting the shield to the Vext side, do not connect the shield to the output ter-
minal of the PWX750ML.
