Installation and Maintenance Guidelines

On-Site Wiring

• Current transformers should be installed close to busbars or distribution cabinets to maintain phase consistency.
• Voltage sampling terminals must be connected to corresponding phases and neutral lines.

Chassis Fixing

• Secure the chassis to the inner wall of the distribution cabinet using bolts or brackets, ensuring it is level for optimal heat dissipation.

Power Supply Check

• Verify the normal operation of the internal 24 V DC power supply. For external AC power supply, inspect the power switch and fuses.

Communication Configuration

• After initial power-on, log in to the Web/PC software via Ethernet or COM interface to configure IP address, subnet mask, and communication protocols (Modbus/TCP, DNP3, etc.).

Firmware Upgrade

• Regularly check for firmware updates on Eaton’s official website and upgrade via secure USB or network methods.

Calibration and Verification

• It is recommended to perform on-site calibration every 2 ~ 3 years, verifying current, voltage, and power readings using known loads or calibration instruments.

Troubleshooting

• If the device self-test light indicates an abnormality, first check the power supply, communication links, and memory card status. If necessary, download logs via the on-site display or remote Web interface for analysis.
