1, high-precision regulator during power-up, do not open the power supply or teaser power supply input and output connections to prevent electric shock or other electrical accidents.
2, power supply input and output connections must be reasonably arranged to prevent the stampede frayed, causing leakage accidents.
3, the power supply must be grounded, because they do not run a ground wire and cause electric shock or personal injury, the responsibility of the user.
4, the power supply can not be connected to the ground heating pipes, water pipes, gas pipes and other public facilities, in order to avoid infringement of third party rights or harm.
5, should regularly check the input and output connections with high precision regulator, in order to avoid loose or fall off, thus affecting the normal use and high-precision electrical safety regulator.
6, cable optional precision regulator must reach a predetermined able to carry sufficient current capacity of the cable.
7, high-precision regulator should be gently, while working to avoid severe vibration;
8, to ensure high-precision regulator Brush spring has enough pressure to avoid carbon brushes and coil arcing contact surface;
9, non-professionals do not disassemble the power supply or power supply for maintenance.
