Page 17 ■ Installation of inverters in horizontally parallel spots: When installing inverters side by side, please ensure a distance of at least 5cm between side covers of the inverter and inner walls of the cabinet, between one inverter and another. Otherwise, heat dissipation of inverters may be insufficient.
Page 18 ■ Installation of inverters in vertically parallel spots: Whenn installing inverters in vertically parallel spots, please ensure a distance of at least 20cm between side covers of the inverter and inner walls of the cabinet, between one inverter and another. Ensure as well efficient ventilation and cooling for each inverter.
Page 19 ■ Installation location of ventilators in the cabinet: ■ Special notes: ◆ When several inverters are installed in the control cabinet, ventilators must be set up in proper spots inside the cabinet. ◆ Make sure the air brought from outside of the cabinet flows through the heating dissipation passage of the inverter, efficiently taking away the heat generated while the inverter is running.

Page 49: Test Run Of The Inverter
6-1-3 Test run of the inverter In order to confirm basic functioning specifications of the inverter, it is recommended to run tests and confirm all the codes in factory settings. This operation relies on the LCD operation panel included in the inverter, so please refer to instructions on LCD operation panel usage in Chapiter 5.
Page 50 Step 5: Power off: When confirmations are complete, please cut off the power supply. Since there is electric energy stored in the internal electrolytic capacitor, the LCD of the inverter will go out in a certain time. However, there is still some remaining voltage inside, so please do not start connecting or disconnecting wires right after the power is cut off, and wait until CHAGE light is completely off.
