D Solderless Terminals for Control Circuit Terminals
The use of solderless terminals for the control circuit terminals is recommended
because solderless terminals are easy to connect securely.
Note When using the following solderless terminal, make sure that the wire size is
2
0.5 mm .
D Wiring Method
1. Loosen the terminal screws with a thin-slotted screwdriver.
2. Insert the wires from underneath the terminal block
3. Tighten the terminal screws firmly to a torque of 0.5 NSm.
Note 1. Always separate the control signal line from the main circuit cables and other
power cables.
Note 2. Do not solder the wires to the control circuit terminals. The wires may not con-
tact well with the control circuit terminals if the wires are soldered.
Note 3. The end of each wire connected to the control circuit terminals must be stripped
for approximately 5.5 mm.
Strip the end for 5.5 mm
if no solderless terminal
is used.

Note 4. Connect the shield to the ground terminal of the inverter. Do not ground the shield
on control side.
Note 5. Cover the shield with tape so that the shield will not come into contact with other
signal wires or machines.

Note Applying a torque of greater
than 0.5 NSm may damage the
terminal block. If the tightening
torque is insufficient, however,
wires may be disconnected.
