Chapter 2 Installation and Wiring
After removing the cover of input/output terminals and control terminals, check if 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. All the units must be grounded directly to a common ground terminal to prevent lightning
strike or electric shock and also for decreasing the noise interference.
3. 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.
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
brushless DC motor drive.
2. Only qualified personnel familiar with brushless DC motor drives is allowed to perform
installation, wiring and commissioning.
3. Make sure that the power is off before doing any wiring to prevent electric shock.
CAUTION!
1. Use wire gauges that comply with the local regulations during wiring.
2. Check following items after finishing the wiring:
A. Are all connections correct?
B. No loose wires?
C. No short-circuits between terminals or to ground?
