Channel-to-Channel Isolation
The relay provides channel-to-channel isolation across its current input circuits, ensuring accurate measurement of phase, zero-sequence, and sensitive ground currents. Analog outputs are isolated to prevent cross-talk with control power circuits. Enhanced display and keypad functions improve deterministic configuration without affecting relay protection logic.
Frequently Asked Questions
Q: What is the difference between G5 and S5 inputs? A: G5 represents 5 A zero-sequence ground current inputs, while S5 represents 5 A sensitive ground current inputs for finer detection of ground faults.
Q: Can the relay operate under both AC and DC control power? A: Yes, the HI option supports 88–300 VDC and 70–265 VAC at 48–62 Hz.
Q: What enhancements are included in the E suffix? A: The E suffix provides a larger LCD display and improved keypad for configuration and monitoring.
Field Installation Guidelines
- Mount the relay securely in control panels with adequate clearance for airflow.
- Ensure wiring for current inputs is routed separately from communication cabling.
- Verify grounding and shielding practices to minimize interference.
- Confirm rear terminal connections for analog outputs and breaker LED indicators.
- De-energize control power before insertion or removal to prevent undefined states.
