Installation
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.
Note 6. Tighten screws to a torque of 0.5 to 0.6 NSm. Tightening screws to a torque exceeding this
value may damage terminal blocks. On the other hand, loosely tightened screws may cause
malfunctions or short-circuits.
Strip the end for 7 mm if
no solderless terminal is
used.
