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.

H Wiring Control Circuit Terminals
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.
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 contact 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 approxi
-
mately 7 mm.
Note 4. Use a shielded wire for the ground terminal.
Note 5. Insulate the shield with tape so that the shield will not touch any signal line or device.
Strip
the end for 7 mm if
no solderless terminal is
used.
