Mitsubishi Electric A800-GF Instruction Manual page 2

Thank you for choosing this Mitsubishi Electric inverter.
This Instruction Manual describes handling and cautions about the hardware, such as installation and wiring, for the FR-A802
(separated converter type) that are different from the FR-A800.
Information about the software, such as basic operations and parameters, is described in the FR-A800 Instruction Manual (Detailed)
in the CD-ROM enclosed with the product.
In addition to this manual, please read the manuals in the enclosed CD-ROM carefully. Do not use this product until you have a full
knowledge of the equipment, safety information and instructions.
Please forward this Instruction Manual to the end user.
Safety Instructions
Do not attempt to install, operate, maintain or inspect this
product until you have read through this Instruction Manual
(Detailed) and supplementary documents carefully and can
use the equipment correctly. Do not use this product until you
have a full knowledge of this product mechanism, safety
information and instructions.
Installation, operation, maintenance and inspection must be
performed by qualified personnel. Here, an expert means a
person 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 (Detailed), 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

hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.

The
consequence according to conditions. Both instruction levels
must be followed because these are important to personal
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. Otherwise you may get an electric shock.
 Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits 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 product 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 inverter in compliance with EN
standard must be used.
 Any person who is involved in wiring or inspection of this product
shall be fully competent to do the work.
 This product body must be installed before wiring. Otherwise you
may get an electric shock or be injured.
 Do not touch the setting dial or keys with wed hands. Doing so
may cause an electric shock.
 Do not subject the cables to scratches, excessive stress,heavy
loads or pinching. Doing so may cause an electric shock.
 Do not change the cooling fan while power is ON as 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. Doing so may cause an electric shock.
 Before wiring or inspection for a PM motor, confirm that the PM
motor is stopped as a PM motor is a synchronous motor with
high-performance magnets embedded inside and high-voltage is
generated at the motor terminals while the motor is running even
after the power of this product is turned OFF. In an application,
such as fan and blower, that the motor may be driven by the
load, connect a low-voltage manual contactor at this product
output side and keep it open during wiring and inspection of this
product. Otherwise you may get an electric shock.
level may even lead to a serious
 Fire Prevention
CAUTION
 Inverter must be installed on a nonflammable wall without holes
(so that nobody touches the inverter heat sink on the rear side,
etc.). Installing it to or near flammable material may cause a fire.
 If the inverter becomes faulty, the inverter power must be
switched OFF. A continuous flow of large current may cause a
fire.
 Be sure to perform daily and periodic inspections as specified in
the Instruction Manual. There is a possibility of explosion,
damage, or fire if this product is used without inspection.
 Injury Prevention
CAUTION
 The voltage applied to each terminal must be the ones specified
in the Instruction Manual. 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 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 burns.
 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.
CAUTION
Transportation and installation
 To prevent injury, wear cut-resistant gloves when opening
packaging with sharp tools.
 Use proper lifting techniques or a trolley when carrying products.
 Do not stand or rest 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 off or fail.
 During installation, caution must be taken not to drop the inverter
as doing so may cause injuries.
 The product must be installed on a 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.
 Foreign conductive objects must be prevented from entering the
inverter. That includes screws and metal fragments or other
flammable substance such as oil.
 As the inverter is a precision instrument, do not drop or subject it
to impact.
 The surrounding air temperature for LD, ND (initial setting), and
HD models must be between 0 and +50°C (non-freezing). The
surrounding air temperature for SLD must be between 0 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
page 17 for details.)
