TP-Link T1600G-28PS Jetstream Smart Switch Installation Guide - Page 12

JetStream Smart Switch 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 following table. Environment Operating Storage Temperature 0 °C to 50 °C (for TL-SG2210MP/TL-SG2428P/TL-SL2428P) 0 °C to 40 °C (for other switches) -40 °C to 70 °C Humidity 10% to 90%RH Non-condensing 5% to 90%RH Non-condensing Clearness The dust accumulated on the switch 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 Switch, 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.
