If the single-phase motor has been adjusted its steering at the factory, when changing, make sure that the turning is correct and avoid affecting the machine. performance.

After the wiring is completed, make sure that the machine control appliance is not faulty and input the matching power supply. At the same time, all the electrical boxes must be covered before power-on, otherwise there will be electric shock and fire hazard.

It is not a professional who should not perform maintenance and inspection on this unit, and should perform disassembly and assembly inspection in case of power failure to avoid electric shock and fire.

Please do not remove the electric box, the electric box door, the side panel of the machine body and some safety protection devices. This method will make the machine in dangerous operation state, which is very dangerous!

The total power switch on the control panel should be operated as little as possible. When the machine is stopped, only the temperature switch and the user power switch need to be turned on and off.

All of these are installation methods for the constant temperature and humidity test chamber power supply, and it is hoped that users who use the constant temperature and humidity test chamber will be helpful.
