Installing more than one unit in a cabinet

E6580757

•Install surge suppressor on any magnetic contactor and relay coils used around the inverter.

•Install noise filters if necessary.

•Install EMC plate (attached as standard) and shielded wires fit with the EMC plate.

■Installing more than one unit in a cabinet

If you are installing two or more inverters in one cabinet, pay attention to the following.

•Ensure a space of at least 5 centimeters on the left and right sides of the inverters.

*If the inverters are horizontally arranged with no space between them (side-by-side installation), re- move the ventilation seals on top of the inverters and operate at 40°C or less (model of 3.7kW or less) or 50°C (model of 5.5kW or more).

•Ensure a space of at least 20 centimeters on the top and bottom of the inverters.

•Install an air deflecting plate so that the heat rising up from the inverter on the bottom does not affect the inverter on the top.
