Appearance
The appearance of SJ200 follows below.
OPE
I/O PCB (PCB3)
Power PCB (PCB2)
OPE is a control unit.
Formally OPE is attached to SJ200.
But another OPE can be used optionally.
This part is a logic circuit.
It has a microcomputer,
which does calculation of the
intelligent input, output, communication task
and so on
Core PCB (PCB1)
This part is a power circuit.
It has a translator
This part is a core circuit.
It has a microcomputer , which manages INV main
function.
IGBT / DM
IGBT / DM. is a transistor unit for outputting to the
motor. It depends on the capacity and the voltage class
whether IGBT or DM is used.

Inverter Specifications Label
The Hitachi SJ200 inverters haveproduct labels located on the right side of the housing,
as pictured below. Be sure to verify that the specifications on the labels match your
power source, motor, and application safety requirements.
Model Number Convention
The model number for a specific inverter contains useful information about its operating
characteristics. Refer to the model number legend below:
Power Input Rating:
frequency, voltage, phase, current
Inverter model number
Motor capacity for this model
Output Rating:
Frequency, voltage, current
Manufacturing codes:
Lot number, date, etc.
Specifications label

Unpacking and Inspection
Please take a few moments to unpack your new SJ200 inverter and perform these steps:
1. Look for any damage that may have occurred during shipping.
2. Verify the contents of the box include:
a. One SJ200 inverter
b. One Instruction Manual
c. One SJ200 Quick Reference Guide
3. Inspect the specifications label on the side of the inverter. Make sure it matches the
product part number you ordered.
Main Physical Features
The SJ200 Series inverters vary in size accord-
ing to the current output rating and motor size
for each model number. All feature the same
basic keypad and connector interface for consis-
tent ease of use. The inverter construction has a
heat sink at the back of the housing. The larger
models include a fan(s) to enhance heat sink
performance. The mounting holes are pre-
drilled in the heat sink for your convenience.
Smaller models have two mounting holes, while
larger ones have four. Be sure to use all the
mounting holes provided.
Two chassis GND screws are located on the
metal tab on the heat sink at the bottom of the
inverter. Never touch the heat sink during or just
after operation; it can be very hot.
The electronics housing and front panel are built
onto the front of the heat sink.
Inverter Keypad - The inverter uses a digital
operator interface, or keypad. The four-digit
display can show a variety of performance
parameters. LEDs indicate whether the display
units are Hertz or Amperes. Other LEDs
indicate Power (external), and Run/Stop Mode
and Program/Monitor Mode status. Membrane
keys Run and Stop/Reset, and an output
frequency potentiometer (speed setting knob)
control motor operation. The FUNC., , and
keys allow an operator to navigate to the
inverter’s functions and parameter values. The
Store key is used when changing a setting.
