IMPORTANT

This mercury burner power supply unit is only designed for use with Olympus mercury burner light source
attachments. When using this power supply unit, always refer to the instruction manual for the AX, BX, BX2,
IX, etc., reflected light fluorescence module.

SAFETY PRECAUTIONS

1. The applicable lamp housing is a mercury burner configuration Olympus lamp housing (U-ULH, U-ULS100HG,
U-LH100HG, etc.)

2. The high pressure mercury burner (mercury arc lamp) used should be a USH102D burner (mfd. by Ushio Electric) or
HBO103W/2 burner (mfd. by OSRAM).

The ultraviolet rays emitted by the burner are harmful for the eyes and should not be directly looked at with
unprotected eyes. Consequently, the burner should never be turned ON as long as the lamp housing is not
mounted on the microscope.

3. When the burner hour counter of the power supply unit indicates 200 or 300 hours, turn the main switch to “O" (OFF) and
allow the mercury burner to cool for at least 10 minutes before replacing it.

High-pressure gas is sealed within the mercury burner. Thus, if it is continued to be used past its service life
expectancy, the glass tube may deform and may sometimes rupture.

4. When disposing of the mercury burner, always follow national and local laws and guidelines.

5. The power supply unit contains high-voltage components. Never attempt to modify or disassemble the power supply unit.

6. High voltage is applied to ignite the mercury burner. To prevent any hazards, always turn the main switch on the power
supply unit to “O" (OFF), unplug the power cord plug from the mains outlet and disconnect the mercury burner socket
cord plug from the U-RFL-T and wait for at least 10 minutes before replacing the burner.

7. Never switch the main switch to “I" (ON) while the mercury burner socket connection cord plug is not plugged in.
Dangerous high voltage may be output from the output connector.

Safety Symbols

The following symbols are found on the power supply unit. Study the meaning of the symbols, and always use the power
supply unit and the lamp housing in the safest possible manner.

Symbol Explanation

Indicates that the surface becomes hot, and should not be touched with bare
hands.

Indicates that high voltage (upper 1 kV) inside, improper handling could result in an
electric shock to the user.

Before use, carefully read the instruction manual. Improper handling could result in
injury to the user or damage to the equipment.

Indicates that the main switch is ON.

Indicates that the main switch is OFF.

Warning Labels

Warning labels are affixed at parts where special precaution is required when handling and using the equipment. Always
heed the warnings.

1 Getting Ready

1. A power supply unit is a precision instrument. Install it on a level surface. Handle it with care and avoid subjecting it to
sudden or severe impact. To prevent obstruction of the air flow, it is important to make sure to leave at least 100 mm
(4 in.) of free space around and above the power supply unit.

2. Do not use the power supply unit where it is subjected to direct sunlight, high temperature and humidity, dust or
vibrations. (For operating environment conditions, refer to and adhere to the conditions specified in Section 4,
SPECIFICATIONS on page 5.)

3. To avoid a potential shock hazard and ensure the electrical safety, be sure to ground the power cord wire. If the power
supply unit is not grounded, Olympus can no longer warrant the electrical safety and performance of the equipment.

4. Always make sure that the main switch is moved to “O" (OFF) before connecting the power cord plug to the wall outlet.

5. For disposal of the mercury burner after use, please observe the applicable ordinance or regulations of the local
government. Contact Olympus in case of doubt.

2 Maintenance and Storage

1. To clean the lenses and other glass components, simply blow dirty away using a commercially available blower and
wipe gently using a piece of cleaning paper (or clean gauze).
If a lens is stained with fingerprints or oil smudges, wipe it gauze slightly moistened with commercially available absolute
alcohol.

Since the absolute alcohol is highly flammable, it must be handled carefully.
Be sure to keep it away from open flames or potential sources of electrical sparks – for example, electrical
equipment that is being switched on or off. Also remember to always use it only in a well-ventilated room.

2. Do not attempt to use organic solvents to clean the non-optical components of the equipment. To clean these, use a
lint-free, soft cloth lightly moistened with a diluted neutral detergent.

3. Do not disassemble any part of the power supply unit as malfunction or damage may occur.

3 Caution

If the equipment is operated in a manner not specified by this manual, the safety of the user may be imperiled. In addition,
the equipment may also be damaged. Always operate the equipment as outlined in this instruction manual.

The following symbols are used to set off text in this instruction manual.

: Indicates that failure to follow the instructions in the warning could result in bodily harm to

the user and/or damage to equipment (including objects in the vicinity of the equipment).

# : Indicates that failure to follow the instructions could result in damage to equipment.

} : Indicates commentary (for ease of operation and maintenance).
