Heat dissipation

Leave at least 50 mm of clearance around the router for heat dissipation.


  • The router must be installed in a clean, dry, well ventilated site where temperature is controlled within a proper range.
  • The installation site must be free from leaking or dripping water, and heavy dew.

Temperature and humidity

  • Operating temperature: 0°C to 45°C
  • Operating relative humidity: 5% RH to 95% RH (noncondensing)

If the relative humidity exceeds 70%, use dehumidifiers or air conditioners with dehumidification features.


  • The router must be reliably grounded according to grounding requirements.
  • Wear an ESD wrist strap to prevent ESD damages to the router.
  • Ensure that the ESD wrist strap is grounded and in a close contact with your wrist.

Corrosive gases

There must be no acidic, alkaline, or other corrosive gases in the installation site.

Surge protection

  • Signal cables must be routed against walls indoors. Do not deploy signal cables overhead outdoors.
  • Keep signal cables away from power cables and surge protection devices.
