The high and low temperature box is mostly used for electric welders, electronic equipment, electronic devices, parts and raw materials to be stored in the high and low temperature test environment. The adaptability test during transportation and application, and its temperature gradient. Ground stress selection test. Customers are choosing After purchasing a high and low temperature box, in addition to understanding the installation of machinery and equipment, it is also necessary to understand the installation level of electrical equipment to ensure that the machinery and equipment operate normally and smoothly.

1. Pay attention to the volume when installing the switching power supply of the high and low temperature box, and must not use one switching power supply for several mechanical equipment at the same time, in order to prevent damage to the characteristics of the equipment. Even a fault shutdown occurs, so please use a separate control loop.

2. The change of the power supply voltage should not exceed ±5% of the working voltage (the allowable maximum working voltage is ±10%)

3. If it is a 3-phase power supply, be sure to pay attention to the maintenance of the phase failure. (If the 3-phase power supply is powered and the equipment is not in position, it may be the reverse phase and the two adjacent power plugs must be exchanged with each other).

4. Note that there is a terminal block on the back side of the high and low temperature box that requires a grounding device. Please carry out the actual operation of the wire joints in accordance with the technical regulations for electrical equipment.

5. If the wire connector is connected to the tap water pipe, then the tap water pipe must be a metal hose connected to the ground (specially note that not all metal hoses can be properly grounded).

6. If the test product needs to use the switching power supply, do not connect the USB internal switching power supply, which may cause the risk of the test working voltage load being too heavy.

7. When installing the high and low temperature box route, check more for damaged wiring and pipelines.
