Step-by-Step Basic Installation

Wire the Inverter
Input to a Supply
Step 6: In this step, you will connect wiring to the
input of the inverter. All models have the same
power connector terminals [R(L1)], [S(L2)], and
[T(L3)] for three-phase input. The three phases
may be connected in any order, as they are isolated
from chassis ground and do not determine motor
direction of rotation. Please refer to the specifica-
tions label (on the front or side of the inverter)
for the acceptable input voltage ranges!
NOTE: The wiring example to the right shows
an SJ700-110LFU2 inverter. The terminal
locations will vary, depending on the inverter
model (see below). Note the use of ring lug
connectors for a secure connection.
Use the terminal arrangement below corresponding
to your inverter model.
NOTE: Be sure that the power is OFF before changing the jumper settings for [P]/[PD] or for
the EMC filter selection.
Inverter models: –004 to –037LFUF2, –007 to –037HFUF2/HFEF2

NOTE: For -055xxx and -075xxx (5.5–7.5kW) inverter models: The washer on the main
terminal screw (R, S, T, PD, P, N, U, V, W, RB) has two cutouts. To prevent the cable clamping
portion of crimp terminal from going under the washer, align the cutouts with the cable as
shown below. Otherwise, you run the risk of a loose connection and fire.
