1.5 Wiring

• Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with
a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above.
Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a
multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has
dropped to the safe level (+25 VDC or below).

• Qualified electricians should carry out wiring.

Otherwise, an electric shock could occur.

• In general, the covers of the control signal wires are not specifically designed to withstand a high voltage
(i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact with
a live conductor of the main circuit, the insulation of the cover might break down, which would expose the
signal wire to a high voltage of the main circuit. Make sure that the control signal wires will not come into
contact with live conductors of the main circuit.

Failure to observe this precaution could cause an electric shock or an accident.

Noise may be emitted from the inverter, motor and wires.
Take appropriate measures to prevent the nearby sensors and devices from malfunctioning due to such
noise.

An accident could occur.

Perform wiring for the interface card observing the precautions below. Refer to the connection diagrams shown
in Figure 2.2 (Chapter 2) and Figure 3.2 (Chapter 3), and the wiring examples shown in Figure 1.8.

(1) Turn the inverter's power OFF.
(2) Use shielded wires.
(3) To prevent malfunction due to noise, keep the wiring for the interface card away from the main circuit wiring

and other power lines as far as possible. Never install them in the same wire duct.
(4) Complete wiring before turning the inverter ON.
(5) See Table 1.3 for the specifications of the terminal block on the interface card.
When using stripped wires (without attaching a crimp terminal), strip the wire end by 5 to 7 mm. (Figure 1.6)

When using a crimp terminal, attach a vinyl-insulated ferrule.
Loosen the terminal screw, insert the wire end into above the metal part of the terminal block, and tighten

the screw to fasten it. (Figure 1.7)

on Interface Card

• Route the wiring of the interface circuit terminals as far from the wiring of the main circuit as
possible. Otherwise electric noise may cause malfunctions.

• Fix the interface circuit wires with a cable tie inside the inverter to keep them away from the live
parts of the main circuit (such as the terminal block of the main circuit).

1-5

Depending upon the wire type and the number of wires used, the front cover may be lifted by the
wires, which impedes normal keypad operation. If it happens, change the wire type or size.

Route the wires, taking care not to let them go over the control PCB, as shown in Figure 1.8.
Otherwise, malfunctions may occur.

• For inverters with a capacity of 22 kW or below

When grounding the shielded cable, use a
crimp ring terminal with insulation sheath,
R1.25-3 or the like and fasten it together
with the card using this screw.

* Pass the wires from the interface card between the control

circuit terminal block and the front cover.
