10. Be sure of the power voltage and the greatest current possible supplied.
11.
When the “Digital Hand-held Programming Panel” is displayed, please do not
disconnect or dissemble any wiring.
12. No braking resistor is installed within the VFD-V inverter (selective purchasing item),
therefore, be sure to purchase and install the braking resistor if to be used on occasions
when the loading inertia is great or that it is of frequent start/stop.
13. Be sure not to connect the AC power with the terminals U/T1, V/T2 and W/T3 on the
power-generating side of the inverter.
14. Please tightly fasten the screws of the main circuit terminals so as to prevent sparks
generated due to the vibration and loosening of the screws.
15. Wiring of the main circuit and of the control circuit should be separated so as to prevent
erroneous actions. If the interlock connection is needed, please make it an
intersection of 90
°
.
16. If terminals U/T1, V/T2 and W/T3 on the power-generating side of the inverter is in need
of the noise wave-filter, it is then necessary to use the induction-type L-Varistor, but be
sure not to add in the phase-carrying capacitor or the L-C- and R-C-type wave filters.
17. Please use the separating wire as much as possible during control wiring, and be sure
not to expose the peeled-off separation net in front of the terminal to the external.
18. Please use the separating wire or tube as much as possible during power wiring, and
ground these two ends of the separating layer or tube to the ground.
19. If the installation site of the inverter is sensitive to interferences, please have the RFI
wave filters installed, and the nearer the inverter to the installation site, the better. In
addition, the lower the carrier wave frequency of, the less the interferences.
20. If the electric-leakage circuit breaker is installed in the inverter, it could serve as the
protection for the electric-leakage error, and as the prevention on the erroneous actions
of the electric-leakage circuit breaker; please select the sensor current above 200mA
with the action time of more than 0.1 second to have these actions accessible.
