To provide protection against short circuit, furnish the external power source
with a fuse or circuit protector. Ensure that the employed circuit protector is
rated as specified.
Before supplying power to the equipment, thoroughly check the wiring
connections.
Before making power supply wiring connections, make sure that no voltage is
applied to the power cable. Immediately after completion of power supply
wiring, be sure to install the terminal cover.
Ensure that the communication, power supply, motive power, and other cables
are routed apart from each other. It is essential that the inverter, motor,
power regulator, and other motive power cables be routed at least 300 mm
away from the other types of cables. Also, be sure that the communication
and motive power cables are routed within separate conduits.
To avoid noise-induced malfunction, do not bundle the 100 VAC/100 VDC wiring
and network cable together, but route them at least 100 mm away from each
other.
