St ep  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 orde r, 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 changi ng the jumper settings for [P]/[PD] or for 
the EMC filter selection.
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.

The table below lists the nominal current that may leak from only the inverter when the internal 
EMC filter is enabled or disabled. Leakage curre nt is in proportion to input power voltage and 
frequency.  The values do not exclude current  leakage from external devices and equipment 
(e.g., power cables). Inverter mode ls from 75 kW to 132 kW does not have a switch to enable/
disable the internal EMC filter. This complies  EMC directive C3 level in standard condition.

NOTE:  An inverter powered by a portable or emerge ncy diesel power generator may result in a 
distorted power waveform, overheating the generato r. In general, the generator capacity should 
be at least five times that of the inverter (kVA).
CAUTION: Be sure that the input voltage ma tches the inverter specifications:


CAUTION:  Be sure not to power a three-phase-only  inverter with single phase power. Other-
wise, there is the possibility of damage to the inverter and the danger of fire.
CAUTION: Be sure not to connect an AC power su pply to the output terminals. Otherwise, 
there is the possibility of damage to the in verter and the danger of injury and/or fire.
CAUTION: Remarks for using ground fault interrupter breakers in the main power supply: 
Adjustable frequency inverters wi th CE-filters (RFI-filter) and shielded (screened) motor 
cables have a higher leakage curre nt toward Earth GND. Especially at the moment of switching 
ON this can cause an inadvertent trip of ground  fault interrupter breakers. Because of the recti-
fier on the input side of the inverter there is the possibility to stall the switch-off function 
through small amounts of DC current . Please observe the following:
 Use only short time-invariant and pulse  current-sensitive ground fault interrupter 
breakers with higher trigger current.
 Other components should be secured with  separate ground fault interrupter breakers.
 Ground fault interrupter breakers in the power input wiring of an inverter are not an 
absolute protection ag ainst electric shock.
CAUTION: Be sure to install a fuse in each phase  of the main power supply to the inverter. 
Otherwise, there is the danger of fire.
CAUTION:  For motor leads, ground fault interrupter  breakers and electromagnetic contac-
tors, be sure to size these components properly  (each must have the capacity for rated current 
and voltage). Otherwise, there is the danger of fire.

Step 7:  The process of motor selection is beyond the sc ope of this manual. However, it must be 
a three-phase AC induction motor.  It should also come with a chassis ground lug. If the motor 
does not have three power input leads, stop th e installation and verify the motor type. Other 
guidelines for wiring the motor include:
 Use an inverter-grade motor for ma ximum motor life (1600V insulation).
 For standard motors, use an output filter if  the wiring between the inverter and motor 
exceeds 10 meters in length.
Simply connect the motor to the terminals 
[U/T1], [V/T2], and [W/T 3] indicated on the 
inverter to the right. This is a good time to 
connect the chassis ground lug on the drive as 
well. The motor chassis ground must also 
connect to the same point. Use a star ground 
(single-point) arrangement, and never daisy-
chain the grounds (point-to-point).
Use the same wire gauge on the motor and 
chassis ground wiring as you used on the 
power input wiring in the previous step. After 
completing the wiring:
 Check the mechanical integrity of ea ch wire crimp and terminal connection.
 Replace the front panel and secu re the retention screw firmly.
Logic Control 
WiringAfter completing the initial installation and powerup  test in this chapter, you may need to wire 
the logic signal connector for your application. For new inverter users/applications, we highly 
recommend that you first comple te the powerup test in this chapter without adding any logic 
control wiring. Then you will be ready to se t the required parameters for logic control as 
covered in Chapter 4, Operations and Monitoring.
St ep  8 : After mounting and wiring the inverter, 
remove any protective material covering the 
inverter ventilation open ings from Step 3. This 
includes covers over the si de ventilation ports as 
well as the fan outlet area.
CAUTION:  Failure to remove all vent opening 
covers before electrical operation may result in 
damage to the inverter.

Powerup Test
Step 9:  After wiring the inverter and motor, you’re  ready to do a powerup test. The procedure 
that follows is designed for the first-time use of  the drive. Please verify the following conditions 
before conducting the powerup test:
 You have followed all the steps in this chapter up to this step.
 The inverter is new, and is securely mo unted to a non-flammable vertical surface
 The inverter is connected to a power source and motor.
 No additional wiring of inverter c onnectors or terminals has been done.
 The power supply is reliable, and the mo tor is a known working unit, and the motor 
nameplate ratings match  the inverter ratings.
 The motor is securely mounted, an d is not connected to any load.
Goals for the 
Powerup TestIf there are any exceptions to the above conditions  at this step, please take a moment to take any 
measures necessary to reach this  basic starting point. The specific goals of this powerup test 
are:
1. Verify that the wiring to the po wer supply and motor is correct.
2. Demonstrate that the inverter an d motor are generally compatible.
3. Give a brief introduction to the use of the built-in operator keypad.
The powerup test gives you an important starting  point to ensure a safe and successful applica-
tion of the Hitachi inverter. We highly recommend  performing this test before proceeding to the 
other chapters in this manual.
Pre-test and 
Operational 
PrecautionsThe following instructions apply to the powerup te st, or to any time the inverter is powered and 
operating. Please study the foll owing instructions and messages before proceeding with the 
powerup test.
1. The power supply must have fusing suitable for the load. Check the fuse size chart 
presented in Step 5, if necessary.
2. Be sure you have access to a disconnect switc h for the drive input power if necessary. 
However, do not turn OFF power to the inve rter during its operation unless it is an 
emergency.
3. Turn the inverter’s front panel potentiometer (if it exists) to the  MIN position (fully counter-
clockwise).
CAUTION:  The heat sink fins will have a high temperature. Be careful not to touch them. 
Otherwise, there is the danger of getting burned.
CAUTION: The operation of the inverter can be easi ly changed from low speed to high speed. 
Be sure to check the capability and limitations  of the motor and machine before operating the 
inverter. Otherwise, there is the danger of injury.

CAUTION:  If you operate a motor at a frequency higher  than the inverter standard default 
setting (50Hz/60Hz), be sure to check the motor  and machine specifications with the respective 
manufacturer. Only operate the motor at elevated frequencies after getting their approval. 
Otherwise, there is the danger of equipment damage and/or injury to personnel.
CAUTION:  Check the following before and during the  powerup test. Otherwise, there is the 
danger of equipment damage.
 Is the shorting bar between the [P] and [P D] terminals installed? DO NOT power or 
operate the inverter if the jumper is removed.
 Is the direction of the motor rotation correct?
 Did the inverter trip durin g acceleration or deceleration?
 Were the rpm and frequency me ter readings as expected?
 Were there any abnormal motor vibrations or noise?
Powering the 
InverterIf you have followed all the steps, cautions and wa rnings up to this point, you’re ready to apply 
power. After doing so, the following events should occur:
 POWER LED will illuminate.
 The numeric (7-segment) LEDs will di splay a test pattern, then stop at 
0.0.
 Hz LED will be ON.
If the motor starts running unexpectedly  or any other problem occurs, press the STOP key. Only 
if necessary should you remove powe r to the inverter as a remedy.
NOTE: If the inverter has been previously powered and programmed, the LEDs (other than the 
POWER LED) may illuminate differently than as  indicated above. If necessary, you can initial-
ize all parameters to the fa ctory default settings. See “
Restoring Factory Default Settings” on 
page 6–16.

Using the Front Panel Keypad
Front Panel
IntroductionPlease take a moment to familiarize yourself wi th the keypad layout shown in the figure below.
The display is used in programming the inverter’s  parameters, as well as monitoring specific 
parameter values during operation. Many functions are applicable only during the initial instal-
lation, while others are more useful for maintenance or monitoring.
Parameter Editing 
and ControlsThe front panel controls and indi cators are described as follows:
 Run/Stop LED  – ON when the inverter output is ON and the motor is developing torque, 
and OFF when the inverter output is OFF (Stop Mode).
 Program/Monitor LED  – This LED is ON when the inverter is ready for  parameter editing 
(Program Mode). It is normally OFF when  the parameter display is monitoring data 
(Monitor Mode). However, the PRG LED will be ON whenever you are monitoring the 
value of parameter D001. (When the keypad  is enabled as the frequency source via 
A001=02, you can edit the inverter frequency di rectly from D001 monitor display by using 
the Up/Down keys.)
 Run Key Enable LED  – is ON when the inverter is ready to respond to the Run key, OFF 
when the Run key is disabled.
 Run Key  – Press this key to run the motor (the R un Enable LED must be ON first). Parame-
ter F004, Keypad Run Key Routing, determines  whether the Run key generates a Run FWD 
or Run REV command.
 Stop/Reset Key  – Press this key to stop the motor when it is running (uses the programmed 
deceleration rate). This key will also reset an alarm that has tripped.
 Potentiometer  (OPE–SRE only) – allows an operator to directly set the motor speed when 
the potentiometer is enabled for output frequency control.
 Potentiometer Enable LED  – ON when the potentiometer is enabled for value entry.
(OPE–SRE only).
 Parameter Display  – a 4-digit, 7-segment display fo r parameters and function codes.
 Display Units: Hertz/Volts/Amperes /kW/% – These LEDs indicate the units associated 
with the parameter display. When the displa y is monitoring a parameter, the appropriate 
LED is ON. In the case of kW units, both  Volts and Amperes LEDs will be ON. An easy 
way to remember this is that kW = (V x A)/1000.
 Power LED  – This LED is ON when the power input to the inverter is ON.
 Alarm LED  – This LED is ON when an alarm condition has tripped the inverter. Clearing 
the alarm will turn this LED OFF again. See Chapter 6 for details on clearing alarms.
