For Safe Use
1. Electric shock prevention
DANGER
Wait at least 10 minutes after turning the power OFF, check the voltage between L1-L2-L3
and L11-L12 terminals with a tester, etc., before starting wiring or inspections.
Failure to observe this could lead to electric shocks.
Ground the servo amplifier and servomotor with Class 3 grounding or higher.
Wiring and inspection work must be done by a qualified technician.
Wire the servo amplifier and servomotor after installation. Failure to observe this could lead
to electric shocks.
Do not touch the switches with wet hands. Failure to observe this could lead to electric
shocks.
Do not damage, apply forcible stress, place heavy items or engage the cable. Failure to
observe this could lead to electric shocks.
2. Fire prevention
CAUTION
Install the servo amplifier, servomotor and regenerative resistor on noncombustible material.
Direct installation on combustible material or near combustible materials could lead to fires.
Following the instructions in this manual, always install no-fuse breakers and contactors on
the servo amplifier power input. Select the correct no-fuse breakers and contactors using this
manual as a reference. Incorrect selection could lead to fires.
Shut off the main circuit power at the contactors to emergency stop when an alarm occurs.
