注意事项 PRECAUTIONS

1 Install the SPD in series with the line following the TN system connection diagram

2 Verify service voltage (AC) with a voltmeter before installation to ensure it matches the 120-277VAC range (for SPD-20HP-277S)

3 Do not install if measured voltage exceeds the rated continuous operating voltage (320VAC)

4 Disconnect power from the electrical system prior to installation to avoid electric shock

5 Ensure all wiring connections are correct and secure before energizing

6 Regularly check the LED indicator: green on = functional; green off = needs replacement

7 Use a 21A backup fuse for TN power grid installations as specified

8 Avoid exposing the device to conditions beyond its IP66 rating or operating temperature range (-40°C to +75°C)

9 Refer to the manufacturer's official documentation for detailed product info and warranty terms

10 Do not modify the device; unauthorized changes may void warranty and compromise safety
