2.3.7 Wiring for control circuit terminals
In general, sheaths and covers of the control signal cables and wires are not specifically designed to
withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal
cable or wire comes into direct contact with a live conductor of the main circuit, the insulation of the
sheath or 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 cables and wires will not come into contact with live conductors
of the main circuit.
Failure to observe these precautions could cause electric shock and/or an accident.
Noise may be emitted from the inverter, motor and wires.
Implement appropriate measure to prevent the nearby sensors and devices from malfunctioning
due to such noise.
An accident could occur.
Figure 2.12 Example of Control
Circuit Wiring
Table 2.7 lists the symbols, names and functions of the con-
trol circuit terminals. The wiring to the control circuit terminals
differs depending upon the setting of the function codes,
which reflects the use of the inverter.
Put back the main circuit TB cover and then connect wires to
the control circuit terminals. As shown in Figure 2.12, pull the
wires out through the guides on the main circuit TB cover.
Route these wires correctly to reduce the influence of noise,
referring to the notes on the following pages.
