Mitsubishi FR-A800-E 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-A806
(IP55/UL Type 12 specification product) 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 the details of Ethernet communication, refer to the FR-A800-E Ethernet Function
Manual in the enclosed CD-ROM. 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
CAUTION
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
CAUTION
The level may even lead to a serious
consequence according to conditions. Both instruction levels
must be followed because these are important to personal
safety.
 Electric Shock Prevention
WARNING
 While the power of this product is ON, do not remove the
front cover or the wiring cover. Do not run this product with
the front cover or the wiring cover removed. Otherwise you
may access the exposed high voltage terminals or the
charging part of the circuitry and 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 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.
 Never touch the motor terminals, etc. right after powering
OFF as the DC voltage is applied to the motor for 1 second
at powering OFF if the main circuit capacitor is measured.
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.
 Fire Prevention
CAUTION
 Inverter must be installed on a nonflammable wall without
holes (its components cannot be touched from behind).
Mounting 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.
 Resistors cannot be used. 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. 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.
