13.8.4 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, 400V class: 528VAC) 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 13.9.5.)
When circuit protectors are used, it is recommended to use the inertia delay type that will not be tripped by an
inrush current.
13.9 Options
WARNING
Before connecting any option or peripheral equipment, turn off the power and wait
for 20 minutes or more until the charge lamp turns off. Then, confirm that the
voltage between L
and L is safe with a voltage tester and others. Otherwise,
an electric shock may occur. In addition, always confirm from the front of the
converter unit whether the charge lamp is off or not.
CAUTION
Use the specified auxiliary equipment and options. Unspecified ones may lead to a
fault or fire.

CAUTION
Connect protection coordination cables correctly if they are fabricated.
Otherwise, the system may perform unexpected operation.
When fabricating a protection coordination cable, use the recommended wires given in section 13.9.4, and
fabricate a protection coordination cable as shown in the wiring diagram in this section.
