Selection Recommendations
Choose IS200LSGIH1APR1 when your load shedding application requires advanced shedding algorithms or enhanced protection features. Verify “APR1” firmware matches your specific load shedding and protection requirements before commissioning.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and highway connections. Confirm “APR1” 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 IS200LSGIH1APR1 with IS200LSGIH1APR in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all load shedding and gateway functions during commissioning. If replacing an IS200LSGIH1APR with an IS200LSGIH1APR1, verify all protection configurations are compatible with the new firmware before installation. Ensure highway cabling does not exceed maximum recommended length. The IS200LSGIH1APR1 is critical for load shedding management – ensure all settings are verified before placing in service. Regular verification of load shedding and protection coordination is recommended.
