Highway Bridge Intelligent Lighting Energy-Saving Voltage Stabilization Monitoring Terminal Installation Steps:

Step 1: Connect the voltage stabilization device to the distribution board and install the fuse. Note that the fuse rating must match the power rating of the street lighting voltage stabilizer.

Step 2: Connect the power supply of the electrical equipment to the output terminals of the device, ensuring that the rated input voltage of the electrical equipment matches the output voltage of the stabilizer.

Step 3: The correct procedure is to first turn on the stabilizer switch, observe that the indicator light is on and the voltmeter reading is normal, then turn on the electrical equipment switch. The device will then stabilize the voltage normally.

Step 4: If the stabilizer is not used for an extended period, turn off the power switch and store it in a dry box to save household electricity and extend the device's service life.

Step 5: When the device operates beyond its load capacity and the input voltage is low, the output voltage of the stabilizer will also drop. In this case, reduce the load on the device.

Step 6: For electrical equipment such as refrigerators, air conditioners, and water pumps that require motor operation, it is advisable to choose a stabilizer with a capacity at least three times the power of the equipment to ensure that the stabilizer does not fail due to startup current overload or overcurrent protection, such as fuse melting or circuit breaker tripping.

Step 7: Ensure the connecting wires for the device are sufficiently long, avoid high-temperature areas, and do not place heavy objects on them or allow them to be stepped on. Tighten the terminal screws to prevent loose connections.

Step 8: Whether using a three-phase or single-phase voltage stabilizer, after connecting all input and output wires, first turn off the main power switch of the electrical equipment, then turn on the device. Confirm that the output voltage is normal before turning on the load power switch.
