Mitsubishi Electric FR-F862 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-F862
(separated converter type) that are different from the FR-F860.
Information about the software, such as basic operations and parameters, is described in the FR-F860 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 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, 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"
Incorrect handling may cause

to a serious consequence according to conditions. Be sure to
follow the instructions of both levels as they are critical 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, 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. You may accidentally touch the
charged inverter circuits and get an electric shock.
 Before wiring or inspection, power lamp 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).
 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. Doing so may cause 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. Doing so may cause 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
 Inverter must be installed on a nonflammable wall without holes
 If the inverter has become faulty, the inverter 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
