3.2.3 Equipotential Terminal
The symbol represents the equipotential terminal that is used for balancing the
protective earth potentials between the system and other electrical equipment. For the
equipotential terminal location, please refer to “2.8 Power Supply Panel”.
WARNING:

Be sure to connect the equipotential wire before
inserting the power plug into the receptacle; be sure
to remove the power plug from the receptacle before
disconnecting the equipotential wire; otherwise
electric shock may result.
2.
When you connect another device to this system, you
should use the equipotential wire to connect each of
equipotential terminals; otherwise electric shock may
result.
