Off the power use, use precautions
A metal enclosure generally associated with power cord and ground (FG) connected to a reliable ground to ensure safety, can not be mistakenly connected to the zero line shell.
Second, the installed power in the test run, please re-check and proof of the connection terminals, make sure the input and output, AC and DC, single phase and multiphase, positive and negative, such as voltage and current values undoubtedly correct before power run.
Third, the power supply, generally have three or more of the "+" input terminal and "-" output terminal, in fact they belong to an output electrode, only to allow users easy connection, and multiple terminals respectively internal and connected together.
Fourth, in order to achieve sufficient cooling effect, generally installed in the air convection conditions are good, location or installed on the chassis housing spread out through the shell will be hot.
Fifth, power factory previously added resistive load, for use in capacitive or inductive the load should be described in the order in advance
Sixth, the Dual symmetrical with the load, preferred symmetrical output power
Seventh, on the FG is not grounded power user, or shell out a hand touch feeling is normal electrical Ma, when the FG floating around on the earth have 110V AC output, which is within the power structure of the decision.
Eight, AC input power is defined input power = output power / (input voltage * power factor * efficiency)
Nine, the Department of leakage current: More than one power supply in use, intake of the same common ground point, the total leakage current is the sum of each unit the leakage current composition, will protect the ground wire to check the reliability and whether the grounding resistance requirements to protect against electric shock.
