7-2-2 Drive section wiring system diagram
Wire the power supply and main circuit as shown below. Always use a no-fuse breaker (NF) on the
power supply input wire.
Note 1: Each unit is provided with an earth
bar. Do not tighten the grounding
bar together with the other wires.
Instead, wires as shown on the
right.
Note 2: If there are noise-generating
devices (contactor, magnetic
brakes, relay) near the power
supply or drive unit and the drive
unit could malfunction, reduce the
generated noise by installing a
surge killer on the noise-generating
device.
