DC Logic Power Supply Wiring
The Epsilon drive requires a user supplied logic power supply, 24 Vdc ±10%, to power the internal logic of the drive.
Use the table below to determine the current requirements of the application. Users should consider keeping logic
power energized at all times because it helps prevent condensation and maintains position information in the drive.
Logic Power Supply Specification
Figure 19: Logic Power Supply Wiring Diagram
For UL applications, the logic power supply must be a UL recognized or UL listed limited voltage/limited energy or
limited voltage/limited current supply, or a limited voltage supply with overcurrent protection appropriate for the wiring
and not to exceed 12 A. Isolate line connected circuits from low voltage circuits.
For applications to meet the EU Low Voltage Directive, an approved 24V supply must be used and the negative side
must be grounded to PE. PELV circuits must have protective separation for 300 V system voltage from mains
connected circuits, including separation between encoder circuits and motor power wiring. If all circuits connected
