This unit should be grounded singly. Mixed grounding with other devices may
cause malfunction.
Insulate the cabinet from the building to prevent the noise current flowing in
the building from adversely affecting it.
Separate the N line (0V) of the power supply from the frame grounding wire.
Also, connect the frame grounding wiring to the grounding terminal at one
point.
Connect the shielding wire of a multi-core cable to the shield processing
terminal at the cabinet inlet. Wiring inside the cabinet should be free of
shielding wire, if possible, to save space and to ensure a sufficient cable
bending radius.
