7-3 Surge absorber
In order to prevent malfunction, provide the surge absorber on the
coils of the electromagnetic contactors, relays and other devices
which are to be used adjacent of the inverter.
7-4 Cable size and length
If the inverter is connected to a distant motor (especially when low
frequency is output), motor torque decreases because of voltage
drop in the cable. Use sufficiently heavy wire.
Changing the carrier frequency reduce RF1 noise and leakage
current. (Refere to the table below)
