Safety Information
WARNING
● Do not connect or disconnect wiring while the power is on.
● Disconnect all power and wait for several minutes. Do not touch any terminals
before the capacitors have fully discharged.
● Do not modify or disconnect wiring, remove optional extension card or replace
the cooling fan while the power is on.
● Make sure to connect the motor-side grounding terminal. Failure to comply
may result in electric shock due to touching motor housing.
● Do not allow unqualied personnel to do the repair & maintenance work.
● Installation, wiring, commissioning, repair & maintenance, and component
replacement must be performed only by qualied technicians.
CAUTION
● Do not run the AC drive with front cover removed.
● Drawings in the manual are sometimes shown without covers or protective
guards. Remember to install the covers or protective guards as specied rst,
and then perform operations in accordance with instructions.
● Tighten all terminal screws based on specied tightening torque.
● Ensure that input voltage is within permissible range. Incorrect input voltage of
main circuit may result in abnormal running.
● Keep combustible materials far away from the AC drive or mount the AC drive
on incombustible surfaces such as a metal wall.
● Replace the cooling fan in correct ways as specied in this chapter. Ensure
correct air outlet direction of the fan. Incorrect air direction will diminish the
cooling effects.
● Do not connect or disconnect motor while the drive is running. Failure to
comply may result in electric shock and damage to the AC drive.
● Use shielded cables for control circuit wiring. Meanwhile, ground the shield to
the grounding terminal reliably.
● Do not modify the drive circuitry. Failure to comply will damage the AC drive.
● Make sure to connect the output terminals of the AC drive and the motor
terminals correctly.
● If it is necessary to change the motor rotation direction, exchange any two of
UVW cables of the AC drive.
● Do not operate the AC drive that has been damaged. This is to prevent further
damage to external equipments.
