WARNING
Any person who is involved in wiring shoul d be fully competent to do the work.
Before starting wiring, switch power off, then wait for more than 10 minutes, and
after the charge lamp has gone off, make sure th at the voltage is safe in the tester
or like. Otherwise, you may get an electric shock .
Ground the servo amplifier and the servo motor s ecurely.
Do not attempt to wire the servo amplifier and s ervo motor until they have been
installed. Otherwise, you may get an electric shock.
The cables should not be damaged, stressed ex cessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
CAUTION
Wire the equipment correctly and securely. Ot herwise, the servo motor may
misoperate, resulting in injury.
Connect cables to correct terminals to prevent a b urst, fault, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. m ay occur.
The surge absorbing diode installed to the DC r elay designed for control output
should be fitted in the specified directio n. Otherwise, the signal is not output due t o
a fault, disabling the emergency stop and other protective circuits.

Use a noise filter, etc. to minimize the influe nce of electromagnetic interference,
which may be given to electronic equipment used near the servo amplif ier.
Do not install a power capacitor, surge suppres sor or radio noise filter (FR-BIF
option) with the power line of the servo motor.
When using the regenerative brake resistor, s witch power off with the alarm signal.
Otherwise, a transistor fault or the like may overheat the regenerat ive brake
resistor, causing a fire.
Do not modify the equipment.
