2.4 Wiring
After removing the front cover, check if the power and control terminals are clear of debris. Be sure
to observe the following precautions when wiring.
2.4.1 Basic Wiring

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.

Check the following items after completing the wiring:
1. Are all connections correct?
2. No loose wires?
3. No short-circuits between terminals or to ground?
A charge may still remain in the DC bus capacitors with hazardous voltages even if the power
has been turned off. To prevent personal injury, please ensure that the power is turned off
and wait ten minutes for the capacitors to discharge to safe voltage levels before opening the
AC motor drive.
