WARNING
yAny person who is involved in wiring should be fully competent to do the work.
yBefore starting wiring, make sure that the voltage is safe in the tester more than 10
minutes after power-off. Otherwise, you may get an electric shock.
yGround the servo amplifier and the servo motor securely.
yDo not attempt to wire the servo amplifier and servo motor until they have been
installed. Otherwise, you may get an electric shock.
yThe cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
CAUTION
yWire the equipment correctly and securely. Otherwise, the servo motor may
misoperate, resulting in injury.
yConnect cables to correct terminals to prevent a burst, fault, etc.
yEnsure that polarity (+, −) is correct. Otherwise, a burst, damage, etc. may occur.
yThe surge absorbing diode installed to the DC relay designed for control output
should be fitted in the specified direction. Otherwise, the signal is not output due to
a fault, disabling the forced stop and other protective circuits.

yUse a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the servo amplifier.
yDo not install a power capacitor, surge suppressor or radio noise filter with the power
line of the servo motor.
yDo not modify the equipment.
POINT
CN1A and CN1B have the same shape. Wrong connection of the connectors
will lead to a failure. Connect them correctly.
