5.13.5 External Voltage Sense Connections

HAZARDOUS OUTPUT: The power source output may be set to hazardous voltage levels. It provides
basic isolation from the ac input mains. Therefore the external voltage sense must also always be
considered hazardous. Connections must be inaccessible to operator in all situations when ac input
mains voltage is applied.
Always disconnect power supply from the mains before connecting or disconnecting to the
hazardous external voltage sense terminals.
SORTIE DANGEREUSE: La sortie de l´appareil peut être réglée à des niveaux de tension dangereux.
L´appareil fournit une isolation de base du réseau d'entrée AC. Par conséquent, les connexions de
sense externes doivent toujours être considérées comme dangereuses. Les connexions doivent être
inaccessibles à l'opérateur dans toutes les situations où la tension d´entrée secteur est appliquée.
Toujours débrancher l'alimentation secteur avant de connecter ou déconnecter les bornes de
connexions de sense externes.
When using external voltage sense, sense wires must be connected between the rear panel
External voltage sense terminal and the load. These wires do not carry any load current so
can be sized accordingly.
Note: If the external sense connections are not used, the power source will use the local
(internal) sense points at the output terminals instead to sense the output voltage.
This means the sensed voltage may be higher than the voltage at the load as load
wire voltage drops is not compensated when using internal sense.
Note: Units are shipped with the mating External Voltage Sense connector installed and
screwed in place to act as a safety cover. When the external voltage sense
connection is not used, this connector should be left in place.
For three phase sense connection wiring, refer to Figure 5-7 for 3 phase WYE load
connections and Figure 5-9 for three phase DELTA load connections.
