  • Page 18: Products Cover Disassembly

    Description: Please install the insulation baffle icon when the inverter is installed vertically upward. The AT500 series inverter dissipates heat from the bottom to the top. When multiple inverters are required to work together, install them side by side. For application installing multiple inverters, if one row of inverters need to be installed above another row, install an insulation guide plate to prevent inverters in the lower row from heating those in the upper row and causing faults.
