Safety Precautions
●
Before repair work, please read this “Safety
Precautions” carefully and use the unit correctly.
● The notes shown here are categorized as “
Warning” and “ Caution”, but since they all describe
important contents on safety, be sure to observe
them.
● The display and meaning are as follows.

unsafe practice which can result in
severe personal injury or death.
CAUTION
This symbol refers to a hazard or
unsafe practice which can result in
personal injury or product or property
damage.
● Meaning of symbol
A “warning” or “caution” item.
Content that must not be done (prohibited
item).
Content that must be done (mandatory item).
● After the repair work, make a test run to check
whether there is any error and explain the notes on
use to the customer.
1. Notes on repair
WARNING
When performing disassembly repair, be sure to
stop operation and switch off the earth leakage
breaker.
Failure to do so may cause electric shock.
Be careful not to touch the charging unit when
performing a repair or a circuit inspection that
requires a power supply.
Switch off the earth leakage breaker of the unit
before repair work. Failure to do so may cause
electric shock.
Do not repair electrical parts with wet hands.
Doing so may cause electric shock.
Do not spray detergent spray or water on the
unit.
Doing so may cause electric shock or re due to
malfunction or electrical short circuit.
2. Notes on products after repair
WARNING
Be sure to repair the unit with parts that
are described in the service parts list of the
applicable model and use the appropriate tools.
In addition, never modify the product.
Doing so may cause electric shock, overheating
or re.
When moving the unit, be sure to install it securely.
Inadequate strength or incomplete installation
may cause a fall, electric shock, overheating or
re.
Do not damage or modify the power cord.
Doing so may cause electric shock or re.
Placing heavy objects on the power cord, heating
it, or pulling it, may cause damage.
3. Inspection items after repair
WARNING
Scratched or deteriorated power cords or lead
wires must be replaced. Also, do not connect the
power cord partway. Doing so may cause electric
shock, overheating or re.
CAUTION
Check that product mounting positions, wiring
conditions, and connection state such as
soldering, crimp terminal, and so on are normal.
Failure to do so may cause overheating, re or
electric shock.

Note
1. About noise malfunction
Since communication control is performed by pulse signal, it has the property that it is easily affected by external noise.
In normal use, there is no problem since this is taken into consideration on the circuit, but please note that an inuence may
occur depending on the installation state.
<Items that add high frequency noise to the signal line, causing error in the signal pulse and malfunction>
Places susceptible to noise Symptoms Measures
1. Area with strong radio waves in the
vicinity of a broadcasting station
2. Near to wireless station
3. Near to use of high-frequency sewing
machines or arc welding machines
4. Hospitals (such as X-ray rooms)
5. Near to plasma or liquid crystal
televisions
1. Stops in the middle of operation
2. The liquid crystal display ickers
Prevent noise from being received by
the signal wiring
↓
· Keep away from source
· Adopt shielded wire
