Safety Instructions - Mitsubishi Electric FR-CC2-H355K Instruction Manual

Thank you for choosing Mitsubishi Electric inverter.
This Instruction Manual describes handling and cautions about the hardware, such as installation and wiring, for the FR-F802
(separated converter type) inverter that are different from the FR-800.
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. In addition to this manual, read all the relevant instruction manuals on the enclosed CD-
ROM carefully to ensure proper use. Do not use this product until you have a full knowledge of this product's workings, 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 the Instruction Manuals and
appended documents carefully. 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, qualified personnel
means a person who meets all the following conditions:
A person who possesses a certification in regard with
electric appliance handling, or person 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 (for example, light curtain) connected to
the safety control system, or a person who has read these
manuals thoroughly and familiarized themselves with the
protective devices.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION".
Incorrect handling may cause haz-

follow the instructions of both levels as they are critical to
personnel 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 as the inside of this product is
charged. Otherwise you may get an electric shock.
 Before wiring or inspection, check that the LED display of the
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 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 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.
 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 the output side
of this product and keep it open during wiring and inspection of
this product. Otherwise you may get an electric shock.

 Fire prevention
CAUTION
 This product must be installed on a nonflammable wall without
any through holes so that nobody touches the heatsink, etc. on
the rear side of this product. Installing it on or near flammable
material may cause a fire.
 If this product has become faulty, the product 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. If this 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 as 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 this product as it will be extremely hot. Doing so may
cause a burn.
 Additional instructions
The following instructions must be also followed. If this product
is handled incorrectly, it may cause unexpected fault, an injury,
or an electric shock.
CAUTION
Transportation and installation
 Any person who is opening a package using a sharp object, such
as a knife or cutter, must wear gloves to prevent injuries caused
by the edge of the sharp object.
 This product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to injuries.
 Do not stand or place any heavy object on this product.
 Do not stack the boxes containing this product higher than the
number recommended.
 When carrying this product, do not hold it by the front cover.
Doing so may cause a fall or failure of the product.
 During installation, caution must be taken not to drop this product
as doing so may cause injuries.
 This product must be installed on the surface that withstands the
weight of the product.
 Do not install this product on a hot surface.
 The installing orientation of this product must be correct.
 This product must be installed on a strong surface securely with
screws so that it does not drop.
 Do not install or operate this product if it is damaged or has parts
missing.
 Foreign conductive objects must be prevented from entering this
product. That includes screws and metal fragments or other
flammable substance such as oil.
 As this product is a precision instrument, do not drop or subject it
to impact.
 The surrounding air temperature must be between -10 and
+50°C (non-freezing) for this product at LD (light duty) rating or
between -10 and 40? (non-freezing) for this product at SLD
(super light duty) rating. Otherwise the product may be
damaged.
 The ambient humidity must be 95% RH or less (non-condensing)
for this product. Otherwise the product may be damaged. (Refer
to page 17 for details.)
