Product Usage & Installation
- Mounting: The 369 relay is designed for panel mounting. Ensure the cutout follows the standard 1/4 DIN dimensions provided in the manual.
- Wiring: Connect the Phase CTs to the current input terminals. For the “M” (Metering) option, connect the PT (Potential Transformer) inputs to terminals to enable power, frequency, and voltage protection.
- RTD Connection: When utilizing the “R” option, connect motor bearing and stator RTDs using three-wire shielded cables to minimize noise interference.
- Configuration: Use the EnerVista 369 Setup software via the front RS232 port or rear RS485 port to program setpoints, including thermal model constants and overcurrent levels.

Common Questions Q&A
- Q: What does the “HI” in the part number signify?
- A: It refers to the High-voltage control power supply, accepting 125/250 VDC or 110/230 VAC.
- Q: Can I upgrade a standard 369 to include the Metering (M) option?
- A: No, the “M” and “R” options are hardware-specific and must be specified at the time of order.
- Q: Is this relay compatible with variable frequency drives (VFDs)?
- A: Yes, the 369 can be used with VFDs, provided the frequency tracking settings are enabled.
