The power supply used by the unit shall be provided by special line, and the complete internal circuit shall be provided for the unit. The installation and configuration of the circuit shall be in accordance with the voltage and frequency specified in the equipment nameplate; the machine shall not operate under the voltage and frequency beyond the manufacturing scope.
The power supply used by the unit should be provided by a dedicated line. The unit provides a complete internal circuit. The installation and configuration of the circuit are in accordance with the voltage and frequency specified in the equipment nameplate. The machine can not operate beyond the voltage and frequency of the manufacturing range.
>The incoming line of the main power supply of the unit is a five color cable, which is connected to the corresponding terminal block of the electrical cabinet of the unit. When connecting the incoming line of the main power supply of the unit, it is necessary to pay attention to the connection of the thin core wire of the five color cable with the neutral line of the three-phase power supply, the yellow and green wire with the grounding, and the other three wires with the power supply.
The main power supply line of the unit is a five-color cable, which is connected to the corresponding terminal row of the electrical cabinet of the unit.
Before the unit is connected to the main power supply, the three-phase AC power supply shall be checked to ensure that the voltage fluctuation range does not exceed 10% of the indicated voltage and frequency of the equipment. For the voltage fluctuation caused by high load, this inspection is particularly important. The unit must be grounded and equipped with air switch with fuse to ensure that the equipment is insulated from the power supply during inspection and service.
Before the unit is connected to the main power supply, the three-phase AC power supply should be checked to ensure that the range of voltage fluctuation does not exceed 10% of the indicated voltage and frequency of the equipment. It is insulated from the power supply during inspection and service.
The fusing power of the fuse must be consistent with the model and type of the unit installed. The fuse should be installed on the unit control panel which is easy to reach; the cable size and fusing power, power supply cable and main electric fuse must have the corresponding correct size and fusing power for the installed unit. Please refer to the attached electrical data for details; the power supply line of the unit needs to increase the fire power-off protection, so as to find problems in time and reduce unnecessary trouble.
The fusing power of fuses must be consistent with the type and type of installed units. The fuse should be installed on the easy-to-touch unit control board; the cable size and fusing power, power supply cable and main fuse must have the correct size and fusing power for the installed unit. See the attached electrical data for details; the power supply line of the unit needs to be protected against fire and power failure in time. Identify problems and reduce unnecessary troubles.
