Installation and Maintenance
Pre-installation preparation: Verify CT ratios match generator nameplate (typically 5A secondary). Calibrate voltage sensing lines within ±0.5% tolerance. Isolate CAN bus cables from VFDs using ferrite cores. Program unique node IDs (1-127) before network commissioning.
Maintenance recommendations: Perform annual synchronization test using calibrated phase-angle meter. Monitor “Sync Deviation” parameter monthly – values >5° indicate CT phase shift. Replace backup supercapacitor every 7 years. Update firmware during planned outages to maintain cybersecurity compliance.
