1. General information
The apparatus described in this manual is designed to be used by properly trained personnel in a
suitable equipped laboratory. For the correct and safe use of this apparatus it is essential that
laboratory personnel follow generally accepted safe procedures in addition to the safety
precautions called for in this manual.
The covers on this instrument may be removed for servicing. However, the inside of the power
supply unit is a hazardous area and its cover should not be removed under any circumstances.
There are no serviceable components inside this power supply unit. Avoid touching the high
voltage power supply at all times.
Some of the chemicals used in spectrophotometry are corrosive and/or inflammable and samples
may be radioactive, toxic, or potentially infective. Care should be taken to follow the normal
laboratory procedures for handling chemicals and samples.
Safety
Read the following before installing and using the instrument and its accessories. The S2150
Series (S-2150 visible and S2150UV UV/Vis) should be operated by appropriate laboratory
technicians.
Electrical
Before switching on the apparatus, make sure it is set to the voltage of the local power supply.
The power cord shall be inserted in a socket provided with a protective earth contact. The
protective action must not be negated by the use of an extension cord without a protective
conductor.
Warning
Any interruption of the protective conductor inside or outside the apparatus or disconnection of
the protective earth terminal is likely to make the apparatus dangerous. Intentional interruption
is prohibited.
Whenever it is likely that the protection has been impaired, the apparatus shall be made
inoperative and be secured against any unintended operation. NEVER touch or handle the
power supply due to the high voltage.
The protection is likely to be impaired if, for example, the apparatus
• Shows visible damage
• Fails to perform the intended measurements
• Has been subjected to prolonged storage under unfavorable conditions.
