This Instruction Manual (Basic) provides handling information and precautions for use of the equipment.
Please forward this Instruction Manual (Basic) to the end user.
1. Electric Shock Prevention
2. Fire Prevention
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
(Basic) 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 (Basic), the safety instruction
levels are classified into "WARNING" and "CAUTION".
Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.
Incorrect handling may cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
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.
WARNING
CAUTION
CAUTION
z While power is ON or when the inverter is running, do not
open the front cover. Otherwise you may get an electric
shock.
z Do not run the inverter with the front cover or wiring cover
removed. Otherwise you may access the exposed high-
voltage terminals or the charging part of the circuitry and
get an electric shock.
z 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.
z 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.
z 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.
z Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
z The inverter must be installed before wiring. Otherwise
you may get an electric shock or be injured.
z Setting dial and key operations must be performed with
dry hands to prevent an electric shock. Otherwise you
may get an electric shock.
z Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an
electric shock.
z Do not change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
z Do not touch the printed circuit board with wet hands.
Otherwise you may get an electric shock.
z 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.
z 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
can cause a fire.
z If the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
z
When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may excessively overheat due
to damage of the brake transistor and such, causing a fire.
z Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
