Product Installation Diagram

Tips
◇ When installing this product, the horizontal lines between cabinets should be securely and reliably connected
◇ The door of this product features an interlocking mechanism with the main switch, meaning the door can only be opened when the power is off. The other side panels of this product are secured with screws and do not have an interlocking function with the main switch. Therefore, users must ensure that the power is disconnected before removing the side panels for maintenance.
◇ Non-professionals should not attempt to open the cabinet for maintenance or repair.
