<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.
Fill the gap.
