Connection

When connecting the du/dt reactor and Voltage Peak Limiter, you must take into account the

following conditions to ensure that it functions correctly:

● Control cables must be routed separately from power cables. Power cables are the motor

● It is recommended to use shielded motor cables. If a shielded motor cable is used, its

● The ground wire for the motor must be fed directly back to the Power Module.

and power cables are not routed in parallel in a joint cable raceway, even if all the cables

are shielded.
