CONTROL
CIRCUIT
External interconnection
wiring, should be performed
using the fol-
lowing procedures
.
After completion,
be sure to check that connections
are cor-
rect . Never use a control
circuit buzzer check .
(1) Separation of control circuit
leads and main circuit
leads
Signal leads 1 through 32
must be separated from main
circuit
leads L1 (R), L2 (S), L3 (T), (+ 3 (P3),
T1 (U), T2 (V), T3
(W), G
(N) and other power cables
to prevent erroneous oper-
ation
caused by noise interference .
(2) Control circuit
leads 9, 10, 18, 19, 20 (contact
output) must
be separated from
leads 1 to 8, 1 1 to 17, 21,
22
and 25 to 27 .
(3) Use twisted shielded or
twisted-pair shielded wire for the
con-
trol circuit line and connect the
shield sheath to the inverter
terminal 12 . See Fig . 4 . Wiring
distance should be less
than 164
ft (50 m) .
