CAUTIONS WHEN WIRING
Main
Circuits
Use 600 V PVC
insulated wires or
cabtyre cables
with the current
carrying capacities of the com-
bined DC motor
for AC main
circuit terminals
(U, V, W) and DC
main circuit terminals (P,
N) .
Field

Signal
Circuits
MAIN CIRCUIT
EXTERNAL TERMINALS
Use
600 V PVC insulated wires or
cabtyre cables
with the current carrying capacities
of the com-
bined DC
motor for field power circuit terminals
(Uo,
W o, U 1 ,
Wl)
and field circuit
terminals (J,
K) .

Use stranded wires
of cross-section 5.5
mm 2 or larger for field
circuit terminals (J, K) .
Use shielded
wires or twisted wires of twisting
pitches 20 mm or
smaller for
the
speed setting
circuit
terminals (6 to 10) , speed feedback ter-
minals
(2, 3),
tachometer circuit terminals (50 to
52) .
