Power Wiring
Frame 13 400 and 600 Volt Class AC Input Power Wiring
Frame 13 size drives utilize two or three parallel power structures that are
pre-connected to line reactors through a fused input switch.
Important:Parallel wiring must have the same cable dimensions, type and
routing. Non-symmetrical wiring may cause unequal loading
between the converters and reduce the drive’s ability to deliver
current to the motor.
