External Sense Connection - Pacific 110ACX Operation Manual

3.7

EXTERNAL SENSE CONNECTION

The ACX Power Source includes connections for external sense of the output voltage. This
allows measurement of the output voltage at an external sense point. This feature can be
completely disabled, so the wiring detailed in this paragraph is optional.
LETHAL VOLTAGES ARE PRESENT AT THE OUTPUT TERMINALS OF THIS DEVICE!
WHEN EXTERNAL SENSE IS CONNECTED, THE SAME VOLTAGE APPEARS ON THE SENSE TERMINALS.
REFER OUTPUT CONNECTION TO A QUALIFIED ELECTRICIAN.
DES TENSIONS A CARACTERE MORTEL SONT PRESENTES SUR LES BORNES DE SORTIE
DE CET EQUIPEMENT! SI LES SENSE EXTERNES SONT RACCORDEES, LES MEMES TENSIONS
SONT PRESENTES SUR LES BORNES DE SENSE. VEUILLEZ VOUS REFERER A UN ELECTRICIEN
Figure 3.6 shows external sense wiring for the ACX. There is very little current flowing through the
External Sense Feedback lines. Standard 22 AWG, 600 Volt control wire is recommended for this
application. Twisting the External Sense wiring is recommended and, in some cases, can
improve performance. In noisy environments, shielding may become necessary to minimize
interference. If shielded cable is used, be sure to ground the shield at one end only to prevent the
possibility of creating a ground loop.
