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.
Table 2.13 lists the symbols, names and functions of the control 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.
