Power Wiring
This section outlines the basics of the power wiring for the N5350. Sample wiring diagrams are shown later in this
guide.
5.1 Grounding the Control
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power before
you ensure that all grounding instructions have been followed. Electrical shock can cause serious
or fatal injury.
To ensure a safe and trouble-free installation, the N5350 must be properly grounded. Symmetrical voltage on
all three phases relative to ground is optimum and thus it is recommended that the control be supplied from a 4-wire wye
connected source. The center tap of the supply transformer secondary should be solidly grounded per local code. A ground
wire must be pulled in the same conduit with the L1, L2, and L3 connections from the source ensuring that the ground wire
is terminated on the N5350 power terminal block.
5.2 Incoming Power
The N5350 is designed for the incoming power ratings listed below. If your installation does not meet these ratings,
contact your local ABB representative for support.

As stated in the grounding section, the three incoming power wires must be pulled together in a single conduit with the
grounding conductor. These connections are to be made to L1, L2, and L3.
CAUTION: Do not connect AC power to the drive output terminals T1/U, T2, V and T3/W. These terminals are
for supplying power to the motor. Connecting AC power to these terminals may result in damage
to the control.
