Mitsubishi Electric A800 Plus 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.
For details of Ethernet communication, refer to the FR-A800-E-R2R Ethernet Function Manual on the enclosed CD-ROM.
In addition to this manual, please read the manuals on the enclosed CD-ROM carefully. Do not use this product until you have 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
and supplementary 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, 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, the safety instruction levels are
classified into "WARNING" and "CAUTION".

to a serious consequence depending on conditions. Be sure
to follow the instructions of both levels as they are critical to
personal safety.
 Electric shock prevention
WARNING
 Do not remove the front cover or the wiring cover of the inverter
while the inverter power is ON. Do not operate this product with
any cover or wiring cover removed, as accidental contact with
exposed high-voltage terminals and internal components may
occur, resulting in an electrical 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 inverter circuits and get an electric shock.
 Before wiring or inspection, check that the display of the inverter
operation panel is OFF. Any person who is involved in wiring or
inspection shall wait for 10 minutes or longer after the power
supply has been cut 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 must be used for 400 V class of this
product to be compliant with EN standard.
 Any person who is involved in wiring or inspection of this product
shall be fully competent to do the work.
 This product 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. 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.
 Do not touch the printed circuit board or handle the cables with
wet hands. Doing so may cause an electric shock.
 Fire prevention
 The product must be installed on a nonflammable wall without
 If this product has become faulty, the product power must be
 Be sure to perform daily and periodic inspections as specified in
 Injury prevention
 The voltage applied to each terminal must be the ones specified
 The cables must be connected to the correct terminals.
 The polarity (+ and -) must be correct. Otherwise burst, damage,
 While power is ON or for some time after power-OFF, do not
