After removing the front cover, verify that the power and control terminals are clear. Be sure to observe
the following precautions when wiring.
Make sure that power is only applied to the R/L1, S/L2, and T/L3 terminals. Failure to comply may
result in damage to the equipment. The voltage and current should be within the range indicated on
the AC motor drive nameplate (see Section 1-1 Nameplate Information).
All the units must be grounded directly to a common ground terminal to prevent damage from a
lightning strike or electric shock.
Make sure you correctly tighten the main circuit terminal screws to prevent sparks from screws that
have been loosened due to vibration.
Turn off the AC motor drive power before installing any wiring.
A hazardous charge
may still remain in the DC bus capacitors after the power has been turned off.
Measure the remaining voltage before wiring. For your safety, do not perform any
wiring before the voltage drops to a safe level < 25 V
DC
. Performing a wiring
installation while voltage remains may cause sparks and short circuits.
Only qualified personnel familiar with AC motor drives are allowed to perform
installation, wiring and commissioning. Make sure the power is turned off before
wiring to prevent electric shock.
When wiring, choose wires that comply with local regulations for your safety.
Check the following items after finishing the wiring:
1. Are all connections correct?
2. Are there any loose wires?
3. Are there any short circuits between the terminals or to ground?
