Features:
- Provides field termination for SPHSS13.
- Uses the documented NKHS03 module cable.
- Supports hydraulic-servo and LVDT field connections.
NTHS03 is the ABB termination unit used with the SPHSS13 hydraulic servo module and NKHS03 cable.
It provides the field-termination interface for LVDT feedback, servo output and related hydraulic-actuator signals.
Confirm SPHSS13 compatibility, cable type, LVDT wiring, servo-coil arrangement and terminal assignments before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

- The termination unit is used with the documented hydraulic-servo controller and NKHS03 cable assembly.
- Connector keying, terminal numbers, jumpers and shield connections must match the installed turbine-control drawing.
- Photograph and record every conductor and setting before the existing termination hardware is removed.
- LVDT feedback, servo-drive and related status conductors terminate at the unit before reaching the rack controller.
- Feedback type, polarity, excitation and servo-current path must correspond to the configured valve-control function.
- Cable length, grounding and terminal assignments require verification across the complete controller-to-actuator assembly.
- Place the turbine actuator in its approved safe state and isolate hydraulic and electrical energy before service.
- Commission feedback scaling, direction and servo polarity under controlled conditions before automatic control is enabled.
- Complete the required trip, interlock and valve-stroke tests under the site's authorized turbine procedure.
