Wiring
DANGER
a. Do Not conduct any wiring during the system power ON to avoid the electric shock.
b. R/L1,S/L2,T/L3 are power inputs (electric source terminals) and U/T1,V/T2,W/T3
are drive’s outputs to a motor. Please Do Not connect these input and output
terminals to terminals
P♁, N○
－
, and PR.
c. Once the wiring is complete, the cover of the drive must be put back and must
seal the drive to avoid other’s accidental contact.
d. The drives have three specifications base on the input power source 100V / 200V
/ 400V, Do Not input the voltage exceed the specifications.
e. The grounding terminal(
) must be exactly grounded. Ground the drive in
compliance with the NEC standard or local electrical code.
f. Please refer to the manual page for the screwing torque of the wiring terminal.
g. Please refer to the national or local electric code for the appropriate spec of the
cords and wires.
h. Please install an appropriate Molded Case Circuit Breaker (MCCB) or Fuse at
each path of power lines to a drive.
i. Please install the thermal relay between the individual motor and the drive when
using one drive to propel several motors.
j. Do Not connect power factor leading capacitor, surge absorber, or
non-three-phase motor to the drive’s U/T1, V/T2, or W/T3 side.
k. AC reactor(ACL) installation is required when the power capacity exceeds
500kVA or 10 times or more than the drive rated capacity.
l. Do Not touch the drive or performing any unwiring actions before drive indicator
light turns off after the power off. Use a multi-meter with the DC voltage stage to
measure the cross voltage between
P♁ and N○
－
terminals (The voltage must
be less than 25V).
m. When the motor do the voltage-proof, insulation testing, unwiring the
U/T1,V/T2,W/T3 terminal of drive at first.
CAUTION
a. The CA series outputs are designed to drive a three-phase induction motor. Do
Not use for single-phase motor or using for other purposes.
b. The main circuit and control circuit must be wired separately; control circuit must
use a shielded or twisted-pair shielded wires to avoid possible interferences.
