Smart Switch ■■ Site Requirements To ensure normal operation and long service life of the device, please install it in an environment that meets the requirements described in the following subsection. Temperature/Humidity ȭ ȭ Please keep a proper temperature and humidity in the equipment room. Too high/low humidity may lead to bad insulation, electricity leakage, mechanical property changes and corrosions. Too high temperature may accelerate aging of the insulation materials and can thus significantly shorten the service life of the device. For normal temperature and humidity of the device, please check the following table. Environment Operating Storage Temperature 0℃ ~ 40℃ -40℃ ~ 70℃ Humidity 10% ~ 90%RH Non-condensing 5% ~ 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, please attach much importance to the following items: ■■ Dust the device regularly, and keep the indoor air clean. ■■ Keep the device well grounded and ensure 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, please make sure to take the following measures: ■■ Use the power supply that can effectively filter interference from the power grid. Installation 06
