Selection Suggestions and Precautions

Selecting the right GE IC698PSD300 configuration and ensuring its proper operation requires careful consideration of several factors.

• Sizing and Selection:

  • Power Budget Calculation: Before selecting the GE IC698PSD300, perform a detailed power budget calculation for your RX7i rack. Sum the power requirements (at each voltage level) of the CPU, all I/O modules, communications processors, and any specialty modules. GE provides power consumption data for each module in their technical documentation. Ensure that the GE IC698PSD300 ratings exceed the calculated total with an appropriate safety margin (typically 20-30%).

  • Inrush Current Consideration: Consider the inrush current characteristics of the GE IC698PSD300 when designing the AC supply circuit. Ensure that branch circuit breakers and wiring are adequately sized for both normal operating current and the momentary inrush during power-up.

  • Redundancy Requirements: Determine whether your application requires power supply redundancy. If so, plan for a configuration with two GE IC698PSD300 modules in a redundant arrangement, ensuring that the AC supply circuits are also appropriately redundant (separate branch circuits, possibly from different phases or sources).

  • Future Expansion: When sizing the GE IC698PSD300, consider future system expansion. It is often cost-effective to select a power supply with additional capacity beyond current requirements, as replacing an undersized power supply later involves system downtime and reconfiguration.

• Installation Precautions:

  • Safety First: Always follow GE’s safety instructions when installing the GE IC698PSD300. Ensure that the AC supply is de-energized and locked out before connecting power wiring. Verify that the GE IC698PSD300 is properly grounded according to local electrical codes and GE’s recommendations.

  • Proper Seating: Ensure the GE IC698PSD300 is fully seated in the RX7i rack with the locking mechanism engaged. Incomplete seating can result in poor electrical connections, voltage drops, and intermittent operation that may be difficult to diagnose.

  • AC Supply Quality: Verify that the AC supply feeding the GE IC698PSD300 meets the module’s specifications for voltage, frequency, and capacity. Consider installing surge suppression devices on the AC supply to protect against voltage transients that could damage the power supply.

  • Cooling Considerations: Ensure adequate ventilation around the GE IC698PSD300. The power supply generates heat during operation, and proper airflow is essential for long-term reliability. Do not block ventilation slots on the module or in the enclosure.

  • Separation from High-Voltage Wiring: Maintain appropriate separation between AC power wiring connected to the GE IC698PSD300 and low-voltage signal wiring to prevent electrical noise coupling that could affect sensitive I/O circuits.

• Configuration and Commissioning:

  • Initial Power-Up: Before applying power to the GE IC698PSD300 for the first time, verify that all modules in the rack are properly seated and that no foreign objects or loose wires could cause short circuits. During initial power-up, observe the GE IC698PSD300 front-panel LEDs for proper status indication.

  • Voltage Verification: After power-up, verify that the GE IC698PSD300 output voltages are within specification. While the RX7i backplane distributes power, measuring voltages at test points (where accessible) can confirm proper operation.

  • Load Monitoring: In critical applications, consider implementing program-based monitoring of the GE IC698PSD300 status through the RX7i CPU. This allows the control system to detect power supply issues and take appropriate action, such as alerting operators or initiating controlled shutdowns.

  • Thermal Imaging: During commissioning, consider using thermal imaging to verify that the GE IC698PSD300 and surrounding area are operating at expected temperatures. This provides a baseline for future predictive maintenance.

• Long-Term Considerations:

  • Spare Parts Strategy: For critical applications, maintain a spare GE IC698PSD300 module on-site. Having a spare available can reduce downtime from hours or days to minutes in the event of a power supply failure.

  • Preventive Maintenance: Include the GE IC698PSD300 in regular preventive maintenance inspections. Check for dust accumulation (which can impair cooling), listen for unusual fan noise (if fan-cooled), and verify that all status indicators show normal operation.

  • Capacitor Aging: Be aware that electrolytic capacitors in the GE IC698PSD300 have finite service lives that are affected by operating temperature and load conditions. In high-temperature or continuous-duty applications, consider proactive replacement based on manufacturer recommendations or reliability data.

  • Documentation: Maintain accurate documentation including the GE IC698PSD300 model, serial number, installation date, and any configuration notes. This information is valuable for warranty claims, troubleshooting, and lifecycle management.

  • Firmware Updates: Check periodically for any firmware updates applicable to the GE IC698PSD300. While power supplies typically have minimal firmware, updates may address specific issues or enhance compatibility with newer modules.
