6. Selection Guidance

1. System Voltage: Ensure compatibility with 24 VDC control circuits common in marine applications.
2. Environmental Needs: Select IP66 enclosures for offshore or high-humidity installations.
3. Integration: Use DEIF Power Controller software for seamless synchronization with existing PLCs.

7. Important Notes

• Perform phase sequence verification before initial startup to avoid motor damage.
• Update firmware biannually using DEIF Service Tool to maintain compliance.
• Avoid mounting near high-frequency inverters (>10 kHz) without EMI shielding.
