Ordering instruction
● When this product is installed, the horizontal line between the switchgears should be connected Prrmly and reliably.
● The door of this product has an interlocking function with the main switch, that is, the door can be opened only when the power is cut off. The other side of the product is a screw sealing plate, which has no interlocking function with the main switch, therefore, the user must disconnect the power supply when disassembling the side panel of this product for maintenance.
● Non-professionals should not open the switchgear for maintenance and repair.
