YASKAWA S-7 Series Manual page 10

• Observe the following precautions when wiring the SERVOPACK's main cir-
cuit terminals.
• Turn ON the power supply to the SERVOPACK only after all wiring, includ-
ing the main circuit terminals, has been completed.
• If a connector is used for the main circuit terminals, remove the main circuit
connector from the SERVOPACK before you wire it.
• Insert only one wire per insertion hole in the main circuit terminals.
• When you insert a wire, make sure that the conductor wire (e.g., whiskers)
does not come into contact with adjacent wires.
• Install molded-case circuit breakers and other safety measures to provide pro-
tection against short circuits in external wiring.
There is a risk of fire or failure.
• Whenever possible, use the Cables specified by Yaskawa.
If you use any other cables, confirm the rated current and application environ-
ment of your model and use the wiring materials specified by Yaskawa or
equivalent materials.
• Securely tighten cable connector screws and lock mechanisms.
Insufficient tightening may result in cable connectors falling off during opera-
tion.
• Do not bundle power lines (e.g., the Main Circuit Cable) and low-current lines
(e.g., the I/O Signal Cables or Encoder Cables) together or run them through
the same duct. If you do not place power lines and low-current lines in sepa-
rate ducts, separate them by at least 30 cm.
If the cables are too close to each other, malfunctions may occur due to noise
affecting the low-current lines.
• Install a battery at either the host controller or on the Encoder Cable.
If you install batteries both at the host controller and on the Encoder Cable at
the same time, you will create a loop circuit between the batteries, resulting in
a risk of damage or burning.
• When connecting a battery, connect the polarity correctly.
There is a risk of battery rupture or encoder failure.
