Selection Recommendations
Choose IS200LSGIH1APR for load shedding coordination and gateway applications. Verify “APR” firmware matches your specific load shedding and protection requirements. Deploy for emergency load management systems.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and highway connections. Confirm “APR” firmware supports your specific load shedding and protection requirements. Never interrupt firmware updates. Board draws 2.0A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix variants in redundant pairs. Allow 30 seconds boot time. Test all load shedding and gateway functions during commissioning. The IS200LSGIH1APR is critical for load shedding management – ensure all settings are verified before placing in service. Ensure highway cabling does not exceed maximum recommended length. Regular verification of load shedding and protection coordination is recommended.
