Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and Bus Communication

The hardware processes multi-channel analog and digital telemetry via internal signal conditioning channels, maintaining strict backplane bus communication velocity and firmware flash compatibility. Communication interfaces and I/O density scaling coordinate network data exchange across supervisory architectures without introducing latency into primary feeder protection loops. Internal monitoring registers validate measurement accuracy across all 1 A current input channels, ensuring deterministic execution of automatic reclosing logic and protective trip profiles.

Field Installation Guidelines

1. Ensure all associated switchgear and control circuits are completely de-energized, locked out, and tagged out before handling wiring terminations.
2. Mount the relay securely into the designated panel cutout, ensuring proper chassis grounding via the rear ground stud to mitigate electromagnetic interference.
3. Terminate current transformer (CT) secondary leads to the 1 A input terminals, ensuring shorting blocks are closed prior to wiring and never left open-circuited under load.
4. Connect the auxiliary control power (88-300 VDC / 70-265 VAC) and the 4-20 mA analog output loops to the corresponding rear terminal blocks.
5. Verify all hardware configurations, check indicator functionality including the red breaker closed status LED, and restore system power.
