6.3 Preparation before Electrical Connections

Cables inside the container have been connection before delivery. The electrical connection in this

chapter is mainly the power cable, communication cable and power supply cable related to the

inverter. If the power distribution cabinet has container power supply connection, it is also

included inside the electrical connection.

6.3.1 Installation Tools

Prepare the following tools before installation:



Torque wrench



Screwdriver



Wire stripper



Terminal crimping device



Alcohol blast burner (or hot air blower)



Allen wrench



Meg-ohmmeter or multimeter



Other auxiliary tools or spare parts

6.3.2 Opening the Inverter Front Door

Before electrical connection, user needs to open the inverter front door. Cabinet door keys are

needed to open or close the front door. Proceed as follows to open the front door.
