4. Setup and Installation
This section details the physical installation and electrical connections for the AMC1301 module.
4.1 Physical Installation
The module is a printed circuit board (PCB) designed for integration into a larger system. It features mounting holes for secure attachment.

Mount the module securely within an appropriate enclosure, ensuring adequate ventilation and protection from environmental factors.
4.2 Electrical Connections
The module provides three isolated current acquisition channels. Each channel has input terminals (CH-1, CH-2, CH-3) and corresponding output connectors (OUT1, OUT2, OUT3).

Refer to Figure 2 for the layout of the input and output connections.
- Input Connections (CH-1, CH-2, CH-3): Connect the current signals from your three-phase motor system to the screw terminals labeled CH-1, CH-2, and CH-3. Ensure proper polarity as indicated on the module or in your system design.
- Output Connections (OUT1, OUT2, OUT3): The analog output signals corresponding to the acquired currents are available via the BNC connectors labeled OUT1, OUT2, and OUT3. Connect these to your data acquisition system or control unit using appropriate coaxial cables.
- Power Supply: Connect the module to a stable and regulated power supply. The specific voltage requirements should be marked on the module or detailed in accompanying documentation (not provided in this context). Ensure the power supply is correctly rated for the module's operation.
- Grounding: Proper grounding is crucial for safety and signal integrity. Connect the module's ground to your system's ground reference.
Double-check all connections before applying power to prevent damage to the module or connected equipment.
5. Operating Instructions
Once the module is correctly installed and wired, follow these steps for operation:
- Power On: Apply power to the module's power supply. Observe any indicator LEDs (if present) to confirm power is supplied.
- Signal Input: Ensure the three-phase motor system is operational and providing current signals to the module's input terminals.
- Data Acquisition: Use your connected data acquisition system or control unit to read the analog output signals from OUT1, OUT2, and OUT3. These signals represent the isolated current measurements.
- Monitoring: Continuously monitor the output signals for expected values and any anomalies.
- Power Off: To shut down the system, first disable the current sources to the module, then disconnect the module's power supply.
6. Maintenance
The AMC1301 module is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure longevity and performance.
- Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use solvents or abrasive cleaners.
- Connection Checks: Periodically inspect all electrical connections for tightness and corrosion. Re-tighten screw terminals if necessary.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.
- Visual Inspection: Regularly inspect the PCB for any signs of physical damage, discoloration, or component stress.
