Selecting solderless ring terminal
• Select a solderless ring terminal for a power cable according to the nominal dimensions for cable.
• Apply insulation coating to the connection part of the solderless ring terminal and the power cable.

Connecting the power terminal
• Connect the cables to the terminal board with solderless ring
terminals.
• Properly connect the cables by using certified and rated cables
and make sure to fix them properly so that external force is not
applied to the terminal.
• Use a driver and wrench that can apply the rated torque when
tightening the screws on the terminal board.
• Tighten the terminal screws by complying rated torque
value. If the terminal is loose, fire can occur due to arc heat
generation and if the terminal is too tight, terminal board
could get damaged.

1 Front connection
When connecting two cables to one terminal,
separate the solderless terminal up and down to
prevent it from getting loose. Place the thin cable
upward and the thick cable downward. Fix the power
cable with a cable tie.
Connector
The place where the sheath of the
power supply cable is removed.
