Wiring method and cautions

• Open the front door. The terminal board for the connection of external units is located inside the box.
• Distribute the cables to the outside through the cable holes at the lower section of the box.
• Use the crimp-style terminals. Dimensions shown in the right figure.
• Apply a torque of 0.5 to 0.8 N
terminal so that abnormal operation cannot be caused.
• Use the shielded cables for the analog input/output line signal and the
winding roll pulse input line, and perform grounding (grounding registance
100W or less) on the signal receiving side.
• Do not insert both the input/output cable and the power cable into the same
duct. Do not bind these cables together.
• Generally, set the cable length to 10 m or less to protect the controller from noises.
• We recommend the I/O cable AWG22-14.
• For a powder clutch/brake, select a cable suitable to the rated current.
• For a tension detector, use a dedicated cable (Standard type: 7 m, Explosion-proof type: 20 m) offered as
an accessory.
• Before installing the controller or performing the wiring work, be sure to externally cut off the power of all
the phases. If the power of all the phases is not cut off, you may receive an electric shock, or the product
may be seriously damaged.
• For the grounding terminal of the product and for the sheet metal area of the casing, be sure to perform
grounding (grounding registance 100Ω or less) using wires of 2 mm
performed properly, you may get an electric shock.
• Determine each cable diameter depending on the current capacity. If a cable is too thin, the insulating
sheath of the cable may melt. Use of such a cable may cause electric shocks, electric leakage, or fires.
• At the completion of wiring, be sure to attach the terminal cover supplied with the product to prevent
electric shocks, and then supply power to the product.
• Correctly connect the AC power cable to the specified terminal, and do not use any unused terminals for
any external lines. Improper connection may damage the product.
• Separate the low power cables from the high power cables, and do not connect both types of cables to
the same grounding terminal. The noise of the high power cable may be superimposed on the low
power cable, hence abnormal operation may be caused.
• Even if the cable is too long, do not insert the remaining part of the cable into the casing of this tension
controller to prevent abnormal operation.
• Do not lay the AC power cable on the panel to prevent abnormal operation.
[Note] This product is an electronic equipment in which a micro computer (CPU) is built in. If the CPU has
become out of order, caused by insertion of conductive foreign objects or abnormal noise into the main
body, the output of this product is fixed. When disorder of the CPU is caused by noise, the product can
be recovered to the normal status by turning off the power and turning it on again.
