After removing the front cover, examine if the power and control terminals are clearly noted. Please
read following precautions before wiring.
 It is crucial to cut off the AC motor drive power before any wiring installation are
made. A charge may still remain in the DCBUS capacitors with hazardous voltages
even if the power has been turned off. Therefore, it is suggested for users to
measure the remaining voltage by DC voltage meter before wiring. For your
personnel safety, please do not perform any wiring before the voltage drops to a
safe level < 25 V
sparks and short circuit.
 Only qualified personnel familiar with AC motor drives is allowed to perform
installation, wiring and commissioning. Make sure the power is turned off before
wiring to prevent electric shock.
 Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to
comply may result in damage to the equipment. The voltage and current should lie
within the range as indicated on the nameplate (Chapter 1-1 Nameplate
Information).
 All the units must be grounded directly to a common ground terminal to prevent
lightning strike or electric shock.
 Please make sure to fasten the screw of the main circuit terminals to prevent
sparks which is made by the loose screws due to vibration.
 When wiring, please choose the wires with specification that complies with local
regulation for your personnel safety.
 Check following items after finishing the wiring:
