5 Installation
Wiring a shielded cable
Ground each shielded cable using a metal cable clamp that contacts the entire
periphery of the shielded cable. Install the cable clamp at the tip of the shielded
cable and connect it to an appropriate grounding point.

Notes about installation and wiring
• Connect the motor and inverter directly to their grounding points so as not to
generate difference in grounding electrical potential between the motor/inverter
and control system equipment nearby.
• If a relay or electromagnetic switch is used with the inverter, connect a mains
filter or surge absorber to absorb any surge voltage that may generate from the
relay or electromagnetic switch.
• Minimize the wiring length of each cable and do not loop or bundle any extra
length.
• Wire the power cables such as the motor cable and power supply cable separately
from the signal cables, and keep a minimum distance of 300 mm (11.8 in.)
between the two sets of cables. Also keep as much distance as possible between
the AC input cable and output cable of the mains filter. Provide a minimum
distance of 20 mm (0.79 in.) between the motor cable and power supply cable.
