To ensure that the switch works normally and to prolong its service lifetime the following requirements should be met in terms of installation environment To ensure the normal operation and service lifetime of a switch proper temperature and humidity should be maintained in the equipment room Long lasting high humidity in the equipment room is prone to poor insulation or even leakage of the insulating material Sometimes the mechanical performance deterioration the rustiness and corrosion of some metal parts are also more likely to occur If the relative humidity is too low the captive screws may become loose due to the insulation washer contraction Meanwhile the electrostatic is likely to be produced in the dry environment which will jeopardize the CMOS circuit of the switch The higher the temperature the greater the damage it will do to the switch Long lasting high temperature will speed up the aging process of the insulating materials greatly lower the reliability of the switch and therefore affect its service life seriously Cleanness Requirements Anti Static Requirements Grounding Requirements Examining Installation Site 51 Dust is a hazard to the operating safety of the switch The indoor dust accumulated on the chassis can cause electrostatic absorption which may result in the poor contact of the connector or metal contact point This happens more frequently when indoor relative humidity is low which will not only sh
