Precautions
Important Safety Warnings
[Power]
Operate unit only on the specified supply voltage.
Disconnect power cord by connector only. Do not pull on cable portion.
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards.
Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Grounding]
Ensure unit is properly grounded at all times to prevent electrical shock hazard.
Do not ground the unit to gas lines, units, or fixtures of an explosive or dangerous
nature.
Ensure power cord is firmly plugged into AC outlet.
[Operation]
Do not operate unit in hazardous or potentially explosive atmospheres. Doing so
could result in fire, explosion, or other dangerous results.
Do not allow liquids, metal pieces, or other foreign materials to enter the unit. Doing
so could result in fire, other hazards, or unit malfunction.
If foreign material does enter the unit, turn power off and disconnect power cord
immediately. Remove material and contact authorized service representative if
damage has occurred.
[Transportation]
Handle with care to avoid shocks in transit. Shocks may cause malfunction. When
you need to transport the unit, use the original packing materials or alternate
adequate packing.

[Circuitry Access]
Do not remove covers, panels, casing, or access circuitry with power applied to the
unit! Turn power off and disconnect power cord prior to removal. Internal servicing /
adjustment of unit should only be performed by qualified personnel.
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even
after power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Rack Mount Brackets, Ground Terminal, and Rubber Feet]
To rack mount or ground the unit, or to install rubber feet, do not use screws or
materials other than those supplied. Otherwise, it may cause damage to the internal
circuits or components of the unit. If you remove the rubber feet attached on the unit,
do not reinsert the screws securing the rubber feet.
[Consumables]
The consumables used in unit must be replaced periodically. For further details on
which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.
