If you connect a ground cable to the ground point in the maintenance
compartment, you are advised to use a four-core (L1, L2, L3, and PE)
outdoor cable.
●
You need to prepare OT-M10 terminals that match the cables.

The values in this table are valid only if the PE cable and AC power cable use
the same conductor material. If this is not so, the cross-sectional area of the PE
cable conductor is to be determined in a manner which produces a conductance
equivalent to that which results from the application of this table.
Installing the PE Cable
Step 1 Crimp an OT terminal.
Step 2 Secure the PE cable using the ground screw.
