11.4 Cable flexing life
The flexing life of the cables is shown below. This graph calculated values. Since they are not guaranteed
values, provide a little allowance for these values. The minimum bending radius : Min. 45mm.

11.5 Inrush currents at power-on of main circuit and control circuit
The following table indicates the inrush currents (reference data) that will flow when the maximum permissible
voltage (200V class: 253VAC) is applied at the power supply capacity of 2500kVA and the wiring length of 1m.

Since large inrush currents flow in the power supplies, always use no-fuse breakers and magnetic contactors.
(Refer to section 12.6.)
When circuit protectors are used, it is recommended to use the inertia delay type that will not be tripped by an
inrush current.
