Chapter 2 Installation and Wiring
After removing the front cover (see chapter 1.2.2 for details), check if the power and control
terminals are clear. Be sure to observe the following precautions when wiring.
CAUTION!
1. 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.
2. Check the following items after finishing the wiring:
A. Are all connections correct?
B. No loose wires?
C. No short-circuits between terminals or to ground?
DANGER!
1. 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.
2. All the units must be grounded directly to a common ground terminal to prevent lightning strike
or electric shock.
3. Only qualified personnel familiar with AC motor drives is allowed to perform installation, wiring
and commissioning.
4. Make sure that the power is off before doing any wiring to prevent electric shock.
