REQUIREMENT
z Before supplying power to the equipment, thoroughly check the wiring
connections.
z 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.
z 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.
z Provide with protect elements, such as a fuse and/or a circuit protector, in an
external power supply for short circuit protection. Use the suitable protect
elements for suited rating.
PROHIBITION
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.
