2.1 Cautions on wiring

Wiring
• Following power terminals are cage type ones.
- Input terminals of VFPS1-4007PDE to 4220PDE
- All power terminals of VFPS1-4300PLE to 4900PLE, VFPS1-4300PDE to 4900PDE
For tightening torque and cable stripping length, refer to 1.3.1 2).
• For power terminal other than above, use sleeved pressure terminal to connect. This is because the space between
terminals is small. Connect sleeved pressure terminals so that adjacent terminals do not touch each other.
• For ground terminal, 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 as and short a ground wire as possible and wire it as close as possible to the inverter.
Voltage class
400V
Note1: The recommended cable size is that of the cable (e.g. 600V class, HIV cable) with continuous maximum
permissible temperature of 75°C. The ambient temperature is assumed to be 40°C or below. (The
interconnect cable length is assumed to be 30m or less.)
