Plan your installation space

Confirm the area can safely fit the complete stacked system, with room for ventilation and at least 30mm clearance behind the heatsink. Follow the user manual when stacking or securing modules, and switch off the system and disconnect AC input before adding or removing a module. Check the running and starting power of any appliance before use.
