1、power supply
　　1)The power supply for the high and low temperature impact test chamber uses a three-phase five wire system, with equipment cables consisting of four core wires, three phase wires, and one neutral wire. Please pay attention to the zero line distinction. Due to the partial load of the equipment and the single-phase control system, connecting the wrong neutral wire will cause the equipment to malfunction and be damaged.
　　2)The grounding wire of this equipment has a grounding pole, ensuring good grounding of the equipment can make it safe and reliable. Incorrect connection of neutral and ground wires will result in abnormal operation of the equipment.
　　3)Due to factors such as the user's location, the cable needs to be extended. Please ensure that the rated parameters of the extension cable and power supply used can meet the power requirements of the product.

　　2、venue
　　1)The high and low temperature impact test chamber generates a large amount of heat during use. Please place the device in a well ventilated area.
　　2)Do not use this equipment near flammable materials or explosive environments.
　　3)Do not use in environments with strong magnetic fields and vibrations.

　　Use safety information:
　　1、Do not connect the power supply of the test sample to the device power supply, otherwise it will increase the power load of the device. Unless the device has a power interface for the test sample.
　　2、It is strictly prohibited to test flammable, explosive, highly corrosive, and highly radioactive materials.
　　3、Do not handle or inspect the equipment while it is powered on or in operation.
　　4、High temperature burns, the temperature inside the high and low temperature impact test chamber is very high during high temperature testing. During the experiment or at the end of the test, if it is necessary to open the box, be particularly careful and remember to walk in the direction of opening to avoid burns.
　　5、Low temperature frostbite, the temperature inside the high and low temperature impact test chamber is very low during low temperature testing. During or immediately after the experiment, be particularly careful when opening the box door to avoid frostbite.
　　6、Electric shock, although the equipment has sound measures to prevent electric shock, it is still necessary to pay attention, especially to the electrical control system. Do not touch the electrical parts during operation.
