Installation Instructions
ATTENTION:
Pour ce qui est de la protection contre les courts-circuits (surtension), ce produit dépend de
l’installation électrique du local. Vérifier qu’un fusible ou qu’un disjoncteur de 120 V alt., 20 A U.S. maximum
(240 V alt., 20 A international) est utilisé sur les conducteurs de phase (conducteurs de charge).
WARNUNG:
Dieses Produkt ist darauf angewiesen, daß im Gebäude ein Kurzschluß-bzw. Überstromschutz
installiert ist. Stellen sie sicher, daß eine Sicherung oder ein Unterbrecher von nicht mehr als 240 V
Wechselstrom, 20 A (bzw. in den USA 120 V Wechselstrom, 20 A) an den Phasenleitern (allen stromführenden
Leitern) verwendet wird.
The Ellipse 3000 Encoders support either AC or DC power compatibility. Power and ground
connections for each option are detailed in the following sections.
Rack Grounding Connection
When the Ellipse is rack mounted, the unit grounding jackscrew must be connected to the rack
housing, which in turn must be correctly grounded.
DANGER:
The GROUND STUD connection to the stud on the unit rear is the first to connect and the last to
disconnect.
AC Power and Ground Connections
Connecting an AC power cable to the Ellipse AC connector to ground the encoder.
NOTE:
The AC powered unit should be powered by a power supply cord, approved by related country’s
national electric safety codes for 18AWG three wire cords. The unit should be installed by a qualified
electrician to a grounded socket outlet.
Cable Connections
All Ellipse connectors are located on the rear panel. Connect the data, control and power cables
