Safety Cautions - ADTRAN 6304W Configuration Manual

Pre-Installation Considerations
2
Ensure that the power supply is reliable. The input voltage fluctuation range
•
should be lower than 10%. The power plug should not share one socket with a
hair drier, an iron or a refrigerator.

Safety Cautions

• Read the user manual carefully before using the ONU.
• Do not use any accessory that is not shipped with the ONU without prior con-
sent of the manufacturer. This may cause fire or product damage.
Use the power adapter that is shipped with the ONU.
•
• Do not place any object on top of the ONU.
Keep the ONU dry, ventilated, and clean.
•
• If lightning occurs, unplug the power plug and all connection cables to protect
the ONU against lightning effects.
Clean the ONU using a soft and dry cloth rather than liquid or atomizers. Turn
•
off the ONU before cleaning it.
Turn off the ONU when it is not in use.
•
• Keep ventilation holes clean and prevent any object from entering ventilation
holes. This may cause short circuit and further cause product damage or fire. Do
not spray liquid on the surface of the ONU.
Do not open the case of the ONU, especially when it is turned on.
•
• Before plugging or unplugging the ONU, ensure that the power is off. This is to
avoid surge.
Be careful when unplugging the ONU, as the transformer may be very hot.
