2.3.7
Wiring for Control Circuit Terminals
Generally, the sheath of control circuit wires is not reinforced by any insulation. If the control
circuit wires come into direct contact with the live main circuit terminal, therefore, the sheath
may break. Accordingly, there is a possibility that high voltage on the main circuit may be applied to the control circuit wires. It is DANGEROUS. Be sure to keep the control wires away
from the live main circuit terminals.
An accident or electric shock could occur.
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 2.8 lists the symbols, names and functions of the
control circuit terminals. The wiring to the control circuit terminals differs depending upon the setting up of the inverter
using the function codes.
Basically, replace 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.
