3.1 MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA

BUSINESS TECHNOLOGIES, INC.

KONICA MINOLTA brand products are renowned for their high reliability. This reliability is
achieved through high-quality design and a solid service network.
Product design is a highly complicated and delicate process where numerous mechanical,
physical, and electrical aspects have to be taken into consideration, with the aim of arriving at
proper tolerances and safety factors. For this reason, unauthorized modifications involve a high
risk of degradation in performance and safety. Such modifications are therefore strictly
prohibited. the points listed below are not exhaustive, but they illustrate the reasoning behind
this policy.

3.1.1 Actions requiring special attention

WARNING

• Do not make any modifications to the product
unless otherwise instructed by KMBT.

• Do not use any part not specified by KMBT.

• Do not use any power cord or power plug not
specified by KMBT.

• Use only the protective fuses specified by
KMBT.

Use of any type of fuse or related part not
specified by KMBT makes safety devices
inoperative which may result in a fire from
high heat.

• Do not disable fuse functions or use a wire,
metal clip, solder, or other conductor in place
of the fuse.

Fire may result from high heat.

• Do not disable relay functions (for example,
inserting a piece of paper between relay
contacts to hamper circuit action.)

Fire may result from high heat.

WARNINGS

WARNING

• Do not disable safety functions (for example,
interlocks and safety circuits).

Safety devices become inoperative, resulting
in fire from high heat, electric shock, or
injury.

3.2 POWER PLUG SELECTION

In some countries or areas, the power plug provided with the product may not fit the wall outlet
used in the area. In that case, it is the obligation of the customer engineer (hereafter called the
CE) to attach the appropriate power plug or power cord set in order to connect the product to
the supply.

3.2.1 Power Cord Set or Power Plug

WARNING

• Use a power supply cord set which meets the
following criteria:

- provided with a plug having configuration
intended for the connection to wall outlet
appropriate for the product's rated voltage and
current, and

- the plug has pin/terminal(s) for grounding, and

- provided with three-conductor cable having
enough current capacity, and

- the cord set meets regulatory requirements for
the area.

Use of inadequate cord set leads to fire or electric
shock.

• Attach power plug which meets the following criteria:

• The wires in the power supply cord shall be

WARNINGS

WARNING

- having configuration intended for the connection
to wall outlet appropriate for the product’s rated
voltage and current, and

- the plug has pin/terminal(s) for grounding, and

- meets regulatory requirements for the area.

Use of inadequate cord set leads to the product
connecting to inadequate power supply (voltage,
current capacity, grounding), and may result in fire
or electric shock.

connected to the terminals of the plug in accordance
with the following:

or colored GREEN

or GREEN-AND-YELLOW

• Wrong connection may cancel safeguards within the
product, and results in fire or electric shock.

3.3 CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE

KONICA MINOLTA brand products are extensively tested before shipping, to ensure that all
applicable safety standards are met, in order to protect the customer and customer engineer
(hereafter called the CE) from the risk of injury. However, in daily use, any electrical
equipment may be subject to parts wear and eventual failure. In order to maintain safety and
reliability, the CE must perform regular safety checks.

3.3.1 Power Supply
(1) Connection to Power Supply

• The power outlet should have a capacity of at
least the maximum power consumption and
be dedicated only to the product.

The current that can be passed through the
outlet is limited and any current exceeding
the limit could result in fire.

• If the wall outlet has two or more receptacles
and the product and another electrical
appliance are plugged into this wall outlet,

A SAFETY AND IMPORTANT WARNING ITEMS > 3. SAFETY

WARNINGS

WARNING

make sure that the total load does not exceed
the rating of the wall outlet. The current that
can be passed through the outlet is limited
and any current exceeding the limit could
result in a fire.

• Do not use any conversion plug adapter even
if the power plug shape does not match your
wall outlet.

The shapes of the power plug and the wall
outlet are set according to the voltage and
allowable current. Use of a conversion plug
adapter could result in an abnormal voltage
or insufficient current capacity, leading to a
fire. It may also result in an electric shock
due to a grounding failure.
If the plug shape does not match the wall
outlet, request the user to perform power
source installation work.

A-7

bizhub 235/215/195

• Make sure the power cord is plugged into the
wall outlet securely.

If the power plug is left loose in the wall
outlet, contact failure may occur, leading to
abnormal heating of the power plug and a
risk of fire.

(2) Ground Connection

A SAFETY AND IMPORTANT WARNING ITEMS > 3. SAFETY

WARNINGS

WARNING

WARNING

• Check whether the product is grounded
properly.

If current leakage occurs in an ungrounded
product, you may suffer electric shock while
operating the product.
Connect power plug to grounded wall
outlet.

• Make sure of correct ground connection.

If the grounding wire is connected to an
inappropriate part, there is a risk of
explosion or electric shock. Do not connect
the grounding wire to any of the following
parts:
a. Gas pipe: Gas explosion or fire may

result.

b. Lightning rod: Risk of electric shock or

fire during lightning.

c. Grounding wire for telephone line: Risk of

electric shock or fire during lightning.

d. Water pipe and faucet: These parts do

not serve as a ground connection
because of a plastic part that is very
often installed midway within the water
pipe.

(3) Power Plug and Cord

• When using the power cord set (inlet type)
that came with this product, make sure the
connector is securely inserted in the inlet of
the product.

When a securing measure is provided,
secure the cord with the fixture properly.
If the power cord (inlet type) is not
connected to the product securely, a
contact problem may lead to increased
resistance, overheating, and risk of fire.

A SAFETY AND IMPORTANT WARNING ITEMS > 3. SAFETY

WARNINGS

WARNING

• Do not allow the power cord to be stepped on
or pinched.

Overheating may occur there, leading to a
risk of fire.

• Check whether the power cord is damaged.
Check whether the sheath is damaged.

If the power plug, cord, or sheath is
damaged, replace with a new power cord
(with plug and connector on each end)
specified by KMBT. Using the damaged
power cord may result in fire or electric
shock.

• Do not bundle or tie the power cord.

Overheating may occur there, leading to a
risk of fire.

• Check whether dust is collected around the
power plug and wall outlet.

Using the power plug and wall outlet
without removing dust may result in fire.

• Do not insert the power plug into the wall
outlet with a wet hand.

The risk of electric shock exists.

A SAFETY AND IMPORTANT WARNING ITEMS > 3. SAFETY

WARNINGS

WARNING

• When unplugging the power cord, grasp the
plug, not the cable.

The cable may be broken, leading to a risk
of fire and electric shock.

WARNING

• Never use multi-plug adapters to plug multiple
power cords in the same outlet.

If used, the risk of fire exists.

• When an extension cord is required, use one
that meets the rated current, rated voltage,
and the relevant safety standards of the
country.

Current that can be passed through the
extension cable is limited and fire may
result from the use of an inappropriate type
of an extension cable.
Do not use an extension cable reel with the
cable taken up. Fire may result.
