The installation of power supply
Please use the appropriate screw, fixed the power supply to the right environment, screw length should be less than 6 mm, not to the circuit boards, conductive danger to avoid touching the internal components. Power supply working space should have ventilation channel or exhaust equipment;In order to ensure the safety of using and reduce interference, please ensure that the grounding line should be good grounding, grounding line is greater than the AWGI#. After the installation, please measure the shell with the input, the output, insulation resistance in order to avoid electric shock.
