Mitsubishi Electric FR-F700PJ Instruction Manual page 2

Thank you for choosing this Mitsubishi Inverter.
This Instruction Manual (Applied) provides instructions for advanced use of the FR-F700PJ series inverters.
Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction Manual
and the Instruction Manual (Basic) [IB-0600425ENG] packed with the product carefully to use the equipment to its
optimum performance.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the
inverter until you have read through the 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.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION".
Incorrect
WARNING
hazardous conditions, resulting in
death or severe injury.
Incorrect
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.

1. Electric Shock Prevention
WARNING
 While the inverter power is ON, do not open 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 access
the charged inverter circuits and get an electric shock.
 Before wiring or inspection, power must be switched OFF.
To confirm that, LED indication of the operation panel
must be checked. (It must be 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 536 class 1 and other applicable
standards).
A neutral-point earthed (grounded) power supply for 400V
class inverter 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.
 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. 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.
 IPM motor is a synchronous motor with high-performance
magnets embedded in the rotor. Motor terminals hold 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. When the motor
is driven by the load in applications such as fan and
blower, a low-voltage
connected at the inverter's output side, and wiring and
inspection must be performed while the contactor is open.
Otherwise you may get an electric shock.
