Copeland compressor installation steps

The compressor is regarded as the heart of the refrigeration system, and the actual responsibility of the compressor is to increase the pressure and bring the suction pressure state to the discharge pressure state. Emerson Copeland compressors are used in a wide range of applications and have a high degree of attention. Below, okmarts.com will introduce the steps and precautions for installing Copeland compressors.

The main circuit fuse fusing is a common fault of SCR servo driver. The causes of fuse fusing are as follows

The "phase sequence" of power incoming line is incorrect. Due to the synchronization problem between the trigger pulse and the main circuit of SCR servo driver, there are strict requirements on the "phase sequence" of the input power supply. If the "phase sequence" is not correct, connecting the power supply may immediately cause the fuse of the main circuit of the driver to blow.
