Safety Messages
For the best results with the L100 Series inverter, carefully read this manual and all of
the warning labels attached to the inverter before installing and operating it, and follow
the instructions exactly. Keep this manual handy for quick reference.
Definitions and Symbols
A safety instruction (message) includes a Safety Alert Symbol and a signal word or
phrase such as WARNING or CAUTION. Each signal word has the following meaning:
HIGH VOLTAGE: This symbol indicates high voltage. It calls your attention to items
or operations that could be dangerous to you and other persons operation this equipment.
Read the message and follow the instructions carefully.
WARNING: Indicates a potentially hazardous situation that, if not avoided, can result in
serious injury or death.
CAUTION: Indicates a potentially hazardous situation that, if not avoided, can result in
minor to moderate injury, or serious damage to the product. The situation described in
the CAUTION may, if not avoided, lead to serious results. Important safety measures
are described in CAUTION (as well as WARNING), so be sure to observe them.

Step 1: Indicates a step in a series of action steps required to accomplish a goal. The
number of the step will be contained in the step symbol.
NOTE: Notes indicate an area or subject of special merit, emphasizing either the
products capabilities or common errors in operation or maintenance.
TIP: Tips give a special instruction that can save time or provide other benefits while
installing or using the product. The tip calls attention to an idea that may not be obvious
to first-time users of the product.
Hazardous High Voltage
HIGH VOLTAGE: Motor control equipment and electronic controllers are connected
to hazardous line voltages. When servicing drives and electronic controllers, there may
be exposed components with housings or protrusions at or above line potential. Extreme
care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one hand when checking com-
ponents. Always work with another person in case an emergency occurs. Disconnect
power before checking controllers or performing maintenance. Be sure equipment is
properly grounded. Wear safety glasses whenever working on electronic controllers or
rotating machinery. ii
General Precautions - Read These First!
WARNING: This equipment should be installed, adjusted, and serviced by qualified
electrical maintenance personnel familiar with the construction and operation of the
equipment and the hazards involved. Failure to observe this precaution could result in
bodily injury.
WARNING: The user is responsible for ensuring that all driven machinery, drive train
mechanism not supplied by Hitachi Industrial Equipment Systems Co., Ltd., and process
line material are capable of safe operation at an applied frequency of 150% of the
maximum selected frequency range to the AC motor. Failure to do so can result in
destruction of equipment and injury to personnel should a single-point failure occur.
WARNING: For equipment protection, install a ground leakage type breaker with a fast
response circuit capable of handling large currents. The ground fault protection circuit is
not designed to protect against personal injury.
HIGH VOLTAGE: HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOM-
ING POWER BEFORE WORKING ON THIS CONTROL.
WARNING: Wait at least five (5) minutes after turning OFF the input power supply
before performing maintenance or an inspection. Otherwise, there is the danger of
electric shock.
CAUTION: These instructions should be read and clearly understood before working
on L100 series equipment.
CAUTION: Proper grounds, disconnecting devices and other safety devices and their
location are the responsibility of the user and are not provided by Hitachi Industrial
Equipment Systems Co., Ltd.
CAUTION: Be sure to connect a motor thermal disconnect switch or overload device to
the L100 series controller to assure that the inverter will shut down in the event of an
overload or an overheated motor.
HIGH VOLTAGE: Dangerous voltage exists until power light is OFF. Wait at least five
(5) minutes after input power is disconnected before performing maintenance.
WARNING: This equipment has high leakage current and must be permanently (fixed)
hard-wired to earth ground via two independent cables. L100 Inverter
iii
WARNING: Rotating shafts and above-ground electrical potentials can be hazardous.
Therefore, it is strongly recommended that all electrical work conform to the National
Electrical Codes and local regulations. Installation, alignment and maintenance should
be performed only by qualified personnel.
Factory-recommended test procedures included in the instruction manual should be
followed. Always disconnect electrical power before working on the unit.
CAUTION:
a) Class I motor must be connected to earth ground via low resistive path (< 0.1
)
b) Any motor used must be of a suitable rating.
c) Motors may have hazardous moving parts. In this event suitable protection must
be provided.
CAUTION: Alarm connection may contain hazardous live voltage even when inverter
is disconnected. When removing the front cover for maintenance or inspection, confirm
that incoming power for alarm connection is completely disconnected.
CAUTION: Hazardous (main) terminals for any interconnection (motor, contact
breaker, filter, etc.) must be inaccessible in the final installation.
CAUTION: This equipment should be installed in IP54 or equivalent (see EN60529)
enclosure. The end application must be in accordance with BS EN60204-1. Refer to the
section
Choosing a Mounting Location on page 27
. The diagram dimensions are to
be suitably amended for your application.
CAUTION: Connection to field wiring terminals must be reliably fixed having two
independent means of mechanical support. Use a termination with cable support (figure
below), or strain relief, cable clamp, etc.
CAUTION: A double-pole disconnection device must be fitted to the incoming main
power supply close to the inverter. Additionally, a protection device meeting IEC947-1/
IEC947-3 must be fitted at this point (protection device data shown in
Determining
Wire and Fuse Sizes on page 214
).
NOTE: The above instructions, together with any other requirements highlighted in this
manual, must be followed for continued LVD (European Low Voltage Directive)
compliance.

CAUTION: The inverter is shipped with a plastic cover over the top vent
grill. REMOVE this cover after the installation is complete. Operation
with this cover in place will not allow proper cooling, and damage to the
inverter may result.
