2. If the total wiring distance between inverter and motor is
excessively long and the inverter carrier frequency (main
transistor switching frequency) is high, harmonic leakage
current from the cable will adversely to affect the inverter
and peripheral devices. If the wiring distance between in-
verter and motor is long, reduce frequency can be set by
constant F20.

6-8 Cautionary points for wiring
A. Main circuit
1. Do not connect the cables of the power source side(R,S,T)
to the U V and W output terminals.
2. Connect output terminals U, V and W to motor lead wires U,
V and W. Verify that the motor rotates in the forward direc-
tion (CCW countercolckwise when viewed from the motor
load side) with the forward run command. If the motor rota-
tion is incorrect, exchange any two of output terminals U, V
and W.
3. Never touch the output circuit directly or put the output line
in contact with the inverter case. Otherwise, it may cause
an electrical shock or grounding short. In addition, never
short circuit the output line.
4. Prohibit of connection of phase advancing capacitor of LC/
RC noise filter.
5. The distance between main circuit wires of the inverter and
other equipment is as far as possible.
