2-5 Control Circuit
The external interconnection wiring must be performed with following proce-
dures.
After completing SYSDRIVE 3G3IV interconnections, be sure to check that
connections are correct. Never use control circuit buzzer check.
(1) Separation of control circuit leads and main circuit leads:
Signal leads 1 through 20 must be separated from main circuit leads L1 (R),
L2 (S), L3 (T), B1/(+), B2, (--), B0/(--), T1 (U), T2 (V), T3 (W), and other power
cables to prevent erroneous operation caused by noise interference.
(2) Control circuit leads 9 10 18 19 20 (contact output) must be separated
from leads 1 to 8, 21 22 25 26 27 and 11 to 17.
Use the twisted shielded or twisted-pair shielded lead for the control circuit
line and connect the shield sheath to the inverter terminal 12 (G). See Fig. 3.
