Safety instructions
Do not attempt to install, operate, maintain or inspect the
product until you have read through this Instruction Manual
and appended documents carefully and can use the
equipment correctly. Do not use this product until you have a
full knowledge of the equipment, safety information and
instructions.
Installation, operation, maintenance and inspection must be
performed by qualified personnel. Here, qualified personnel
means personnel who meets all the conditions below.
• A person who took a proper engineering training.
Such training may be available at your local Mitsubishi
Electric office. Contact your local sales office for schedules
and locations.
• A person who can access operating manuals for the
protective devices (e.g. light curtain) connected to the safety
control system. A person who has read and familiarized
himself/herself with the manuals.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION"
Incorrect handling may cause
WARNING
hazardous conditions, resulting in death
or severe injury.
Incorrect handling may cause
CAUTION
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
CAUTION
Note that even the
serious consequence depending on conditions. Be sure to
follow the instructions of both levels as they are critical to
personnel safety.
 Electric shock prevention
WARNING
 Do not remove the front cover or the wiring cover while the power of this
product is ON, and do not run this product with the front cover or the
wiring cover removed as the exposed high voltage terminals or the
charging part of the circuitry can be touched. Doing so may cause an
electric shock.
 Even if power is OFF, do not remove the front cover except for wiring or
periodic inspection as you may accidentally touch the charged circuits of
this product and get an electric shock.
 Before wiring or inspection, LED indication of the operation panel must be
switched OFF. Any person who is involved in wiring or inspection shall
wait for at least 10 minutes after the power supply has been switched OFF
and check that there are no residual voltage using a tester or the like. The
capacitor is charged with high voltage for some time after power OFF, and
it is dangerous.
 This inverter must be earthed (grounded). Earthing (grounding) must
conform to the requirements of national and local safety regulations and
electrical code (NEC section 250, IEC 61140 class 1 and other applicable
standards). A neutral-point earthed (grounded) power supply must be
used for 400 V class inverter to be compliant with EN standard.
 Any person who is involved in wiring or inspection of this equipment shall
be fully competent to do the work.
 The inverter must be installed before wiring. Otherwise you may get an
electric shock or be injured.
 Setting dial and key operations must be performed with dry hands to
prevent an electric shock. Otherwise you may get an electric shock.
 Do not subject the cables to scratches, excessive stress, heavy loads or
pinching. Otherwise you may get an electric shock.
 Do not change the cooling fan while power is ON. It is dangerous to
change the cooling fan while power is ON.
 Do not touch the printed circuit board or handle the cables with wet hands.
Otherwise you may get an electric shock.
─CONTENTS─
 When measuring the main circuit capacitor capacity, the DC voltage is
applied to the motor for 1s at powering OFF. Never touch the motor
terminal, etc. right after powering OFF to prevent an electric shock.
 A PM motor is a synchronous motor with high-performance magnets
embedded in the rotor. Motor terminals holds high-voltage while the motor
is running even after the inverter power is turned OFF. Before wiring or
inspection, the motor must be confirmed to be stopped. In an application,
such as fan and blower, where the motor is driven by the load, a low-
voltage manual motor starter must be connected at the inverter's output
side, and wiring and inspection must be performed while the motor starter
is open. Otherwise you may get an electric shock.
 Fire prevention
 The inverter must be installed on a nonflammable wall without any
through holes so that nobody touches the heat sink, etc. on the rear side
of the inverter. Installing it to or near flammable material may cause a fire.
 If the inverter has become faulty, the inverter power must be switched
OFF. A continuous flow of large current may cause a fire.
 Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing
so could cause a fire.
 Be sure to perform daily and periodic inspections as specified in the
Instruction Manual (Detailed). There is a possibility of explosion, damage,
or fire if this product is used without inspection.
 Injury prevention
 The voltage applied to each terminal must be the ones specified in the
Instruction Manual (Detailed). Otherwise an explosion or damage may
occur.
 The cables must be connected to the correct terminals. Otherwise an
explosion or damage may occur.
 The polarity (+ and -) must be correct. Otherwise an explosion or damage
level may lead to a
may occur.
 While power is ON or for some time after power-OFF, do not touch the
inverter as it will be extremely hot. Touching these devices may cause a
burn.
 Additional instructions
The following instructions must be also followed. If the product
is handled incorrectly, it may cause unexpected fault, an injury,
or an electric shock.
Transportation and installation
 Any person who is opening a package using a sharp object, such as a
knife and cutter, must wear gloves to prevent injuries caused by the edge
of the sharp object.
 The product must be transported in correct method that corresponds to
the weight. Failure to do so may lead to injuries.
 Do not stand or place heavy objects on the product.
 Do not stack the boxes containing inverters higher than the number
recommended.
 When carrying the inverter, do not hold it by the front cover; it may fall or
break.
 During installation, caution must be taken not to drop the inverter as doing
so may cause injuries.
 The product must be installed on the surface that withstands the weight of
the inverter.
 Do not install the product on a hot surface.
 Ensure the mounting orientation of this product is correct.
 Ensure this product is mounted securely in its enclosure.
 Do not install or operate the inverter if it is damaged or has parts missing.
 Prevent conductive items such as screws and metal fragments, or
flammable substances such as oil from entering the inverter.
 As the inverter is a precision instrument, do not drop or subject it to
impact.
 The surrounding air temperature for LD rating must be between -10 and
+50°C (non-freezing). The surrounding air temperature for SLD rating
must be between -10 and +40°C (non-freezing). Otherwise the inverter
may be damaged.
 The ambient humidity must be 95%RH or less (non-condensing).
Otherwise the inverter may be damaged. (Refer to
