CAUTION
 Wait for at least six minutes after turning OFF the power supply
(with a SERVOPACK for a 100-VAC power supply input, wait for
at least nine minutes) and then make sure that the CHARGE indi-
cator is not lit before starting wiring or inspection work. Do not
touch the power supply terminals while the CHARGE lamp is lit
after turning OFF the power supply because high voltage may still
remain in the SERVOPACK.
There is a risk of electric shock.
 Observe the precautions and instructions for wiring and trial
operation precisely as described in this document.
Failures caused by incorrect wiring or incorrect voltage application
in the brake circuit may cause the SERVOPACK to fail, damage the
equipment, or cause an accident resulting in death or injury.
 Check the wiring to be sure it has been performed correctly.
Connectors and pin layouts are sometimes different for different
models. Always confirm the pin layouts in technical documents
for your model before operation.
There is a risk of failure or malfunction.
 Connect wires to power supply terminals and motor connection
terminals securely with the specified methods and tightening
torque.
Insufficient tightening may cause wires and terminal blocks to gen-
erate heat due to faulty contact, possibly resulting in fire.
 Use shielded twisted-pair cables or screened unshielded multi-
twisted-pair cables for I/O Signal Cables and Encoder Cables.
 The maximum wiring length is 3 m for I/O Signal Cables, and 50
m for Encoder Cables or Servomotor Main Circuit Cables.
 Observe the following precautions when wiring the SERVO-
PACK’s main circuit terminals.
• Turn ON the power supply to the SERVOPACK only after all wiring,
including 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 protection against short circuits in external wiring.
There is a risk of fire or failure.
