📖 Product Operating Instructions
🔧 Step 1: Mechanical Installation Mount the relay securely into the designated panel cutout using the provided mounting hardware, ensuring adequate ventilation clearance around the enclosure.
🔌 Step 2: Terminal Connections Wire the power supply, current transformers (CTs), resistance temperature detectors (RTDs), and control outputs precisely as indicated on the terminal wiring diagram printed on the rear housing.
💻 Step 3: Setup and Configuration Energize the unit and configure motor nameplate data, thermal overload curves, and protection trip thresholds via the front-panel interface or using GE EnerVista setup software.
🟢 Step 4: Routine Testing and Operation Perform pre-commissioning functional tests on trip circuits, verify real-time metering values on the display, and monitor ongoing operational status during normal load conditions.
❓ Frequently Asked Questions (Q&A)
💬 Q1: What does the ‘HI’ designation mean in the model number 369-HI-R-0-0-0-0-E? 💡 A1: The ‘HI’ prefix indicates that the relay is equipped with a high-range universal control power supply capable of handling higher AC/DC input voltages.
💬 Q2: Can the 369 relay monitor motor winding temperatures directly? 💡 A2: Yes, the relay includes integrated inputs for RTD sensors (such as Platinum or Nickel) to continuously monitor stator and bearing temperatures.
