■Installation in the side of left / right ：
Pls. assure the space is above 5cm, whatever is between the inside of cabinet and the
outlook frame of Inverter, or between Inverter’s outlook frame while installed in the side of left/right
Or could be caused of not enough of heat dissipation for Inverter.

■Installation more layers in the side of up /down：
Pls. assure the distance is above 20cm, whatever is between the inside of cabinent and the outlook frame of Inverter,
or between the Inverter’s outlook frame, and ensure the ventilation and cooling for each Inverter, or will be caused of
being not enough of heat dissipation.

■Installment site for ventilation fan in the cabinent:
■ Notification:
◆ When several inverters are set in a control cabinet, be sure to local the ventiliation fans properly
to allow free aire circulation.
◆ Ensure the air in the outside of cabinent flow to the Inverter’s heat dissipation route, take those heat from the
Inverter in operation away in efficient.
◆ If the ventiliation fans are located properly, the ambient termperature will rise and affect the cooling of the Inverter.
