Mitsubishi Electric FR-F806-E Hardware 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-F806 (IP55/
UL Type12 specification product) that are different from the FR-F800.
Information about the software, such as basic operations and parameters, is described in the FR-F800 Instruction Manual (Detailed)
in the CD-ROM enclosed with the product. For the details of Ethernet communication, refer to the 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 the
product until you have read through this Instruction Manual
(Detailed) 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, 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 hazardous
Warning
conditions, resulting in death or severe
injury.
Incorrect handling may cause hazardous
Caution
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 inverter power is ON, do not remove the front
cover or the wiring cover. Do not run the inverter 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, LCD 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 in compliance with EN standard must be used.
 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.
 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.
 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
Caution
 Inverter must be installed on a nonflammable wall without
holes (so that nobody touches the inverter heatsink on the
rear side, etc.). Mounting 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.
 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. If a product is used
without any inspection, a burst, breakage, or a fire may
occur.
 Injury Prevention
Caution
 The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.
 The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
 The polarity (+ and -) must be correct. Otherwise burst,
damage, etc. 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.
