Caution
Prohibited
• Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output
(motor side) terminal.
This could cause a fire.
Preventing radio noise
To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's power terminals
(R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).
Control and main power supply
The control power supply and the main circuit power supply for the VF-PS1 are the same. If a malfunction or trip
causes the main circuit to be shut off, control power will also be shut off.
If you want to keep the control circuit alive when the main circuit shuts off due to trouble or tripping, you use a
transformer (down to 400V) and an optional control power supply backup unit (CPS002Z).
Wiring
• For ground terminal G/E use wires of the size that is equivalent to or larger than those given in table below and
always ground the inverter.
Use as large and short a ground wire as possible and wire it as close as possible to the inverter.

Note1: The recommended cable size is that of the cable (e.g. 1500V class cupper cable) with continuous
maximum permissible temperature of 75°C. Ambient temperature is 40°C or less and the wiring distance
is 30m or less.
