• Plug the product into the wall outlets with earthing connection through the power supply cord.

• The socket-outlet shall be installed near the equipment and shall be easily accessible. 

Site Requirements

• Temperature/Humidity

Keep the equipment room at an appropriate level of temperature and humidity. Too much or too little humidity may lead to bad insulation, leakage of electricity, mechanical property changes, and corrosion. High temperatures may accelerate aging of the insulation materials, significantly shortening the service life of the device. To find out the best temperature and humidity conditions for the device, check the Appendix B Specifications.

• Clearness

The dust accumulated on the device can be absorbed by static electricity and result in poor contact of metal contact points. Some measures have been taken for the device to prevent static electricity, but too strong static electricity can cause deadly damage to the electronic elements on the internal circuit board. To avoid the effect of static electricity on the operation of the device, attach much importance to the following items:
• Dust the device regularly, and keep the indoor air clean.
• Keep the device well grounded and ensure that the static electricity has been transferred.

• Electromagnetic Interference

Electronic elements including capacitance and inductance on the device can be affected by external interferences, such as conducted emission by capacitance coupling, inductance coupling, and impedance coupling. To decrease the interferences, make sure to take the following measures:
• Use the power supply that can effectively filter interference from the power grid.
• Keep the device far from high-frequency and strong-current devices such as radio transmitting station.
• Use electromagnetic shielding when necessary.

• Lightning Protection

Extremely high voltage currents can be produced instantly when lightning occurs and the air in the electric discharge path can be instantly heated up to 20,000 °C. As this instant current is strong enough to damage electronic devices, more effective lightning protection measures should be taken.
• Ensure that the rack and the device are well earthed.
• Make sure the power socket has a good contact with the ground.
• Keep a reasonable cabling system and avoid induced lightning.
• Use the signal SPD (Surge Protective Device) when wiring outdoor.
Note: For detailed lightning protection measures, refer to the Lightning Protection Guide.
