Safety Tips for Using Voltage Stabilizer
Correct wiring of the voltage stabilizer
First, according to the power of the purchased voltage stabilizer, select the appropriate wire to connect the input and output terminals of the stabilizer. (Note: The wiring should be strictly in accordance with the wiring tag of the stabilizer when installing. Pay special attention to the fact that the live and neutral wires must not be reversed. The neutral and ground wires must not be confused. The ground and neutral wires cannot be omitted). Turn on the voltage stabilizer switch, the voltage meter output on the panel should dispaly 220V, and the power indicator on the panel is on, indicating that the voltage stabilizer has been working normally. If it is necessary to adjust the output voltage, adjust the voltage potentiometer of the circuit board of the machine and adjust it clockwise to increase the output voltage. Adjust counterclockwise to reduce output voltage (turn off load when adjusting).
Safety device of the voltage stabilizer
The voltage stabilizer below 3 kVA uses fuse for overload or short circuit protection, and the ac voltage stabilizer above 5 kVA uses small circuit breaker or small air switch for overload or short circuit protection. When the voltage stabilizer is working, if fuse is blown or automatic air circuit breaker trips, it should be shut down to check the load and the voltage stabilizer.
Overvoltage protection of the voltage stabilizer
When the output voltage exceeds the voltage stabilizer protection value (the phase voltage protection value is adjusted to 250V±5V at the factory), the voltage stabilizer will automatically protect, reduce or cut the voltage output voltage of the stabilizer, and the over-voltage indicator light will be on, the user should immediately shut down to check the grid voltage or the voltage stabilizer. When the voltage stabilizer is working, if the output voltage is jitter, it may be capacitive or the inductive load is too heavy. The user can adjust the switch on the circuit board in the case to eliminate the jitter (please turn off the load when adjusting). If the shaking cannot be eliminated, it may be caused by too much internal resistance of the input grid line or serious distortion of the input waveform.
If the voltage stabilizer is under overvoltage protection after starting, please check whether the stabilizer is adjusted normally and whether the grid voltage is out of the range of the voltage stabilizer. Switch on the voltage stabilizer and turn on the electrical equipment after the output voltage is stable.
