Note:1. When installing inverters of different sizes in parallel, please align the upper positions of the inverters
before installing. For easier replacement of the cooling fan.
2. When it is inevitable to arrange inverters vertically to minimize space,install guides since heat from the
bottom inverters can increase the temperature on the top inverters, causing inverter failures.
3. Side-by-side installation, that is, when “D” is 0, ensure that the ambient temperature in the cabinet is not
higher than 40°C, and it is not possible to use external keypad or communicate with upper computer through
RS485 interface.
