<Notice>
・Do not remove the ground wire that connects Main Box and Inverter Box.
・Install the transmission cable as shown in the figure above so that the cable is long enough for the Main Box to be
moved for servicing.
・If there are any gaps around the power cable and transmission cable, please be sure to fill these in with a suitable
material to prevent snow from entering, which may cause damage to the electrical parts, and to protect your hands
from direct contact with cables.
・When putting the power cable through the knockout hole without using a conduit tube, deburr the hole and protect
the power cable with protective tape.
・Use a conduit tube to narrow down the opening if there is a possibility of small animals entering the unit.
・When taking the conduit tube out from the bottom part of the unit, caulk around the tube opening to prevent water
infiltration.
