2.4 Electrical Safety
There is no danger of electrical shock during routine operation of the spectrometer, however
the following precautions must be followed to assure user safety and protection of the
instrument.
WARNING
Electrical hazard from electrical shock
A life threatening shock may result when maintenance is performed.
u Place the mains power switch in the OFF position (direction labeled "0" on the switch).
u
Disconnect the device from the electrical power supply before maintenance. Use a
voltmeter to verify that the device is not under power!
u
Be sure that the power supply cannot be reconnected without notice.
u
Ensure that all warning labels are in place.
u Only trained personnel should carry out maintenance.
The safety precautions applicable to any electronic device connected to AC power must be
observed.
Always use the power cable that is delivered with the product.
If replacement of the power cable is necessary, make sure that the ratings with regard to the
power consumption of the device are suitable.
WARNING
Electrical hazard from stored electrical charge
A life threatening shock or material damage may result from a stored electrical charge.
Never touch electrical contacts or semiconductor chips with any object (conductive or non-
conductive) unless all of the following conditions are met:
u
The power switch is off.
u The power plug is disconnected from either the power socket or the main power socket
on the spectrometer.
u The conductive object and you are grounded.
ð
This precaution prevents the possibility of electrical shock from stored charge within the
power supply circuitry or the transfer of static charge that can damage semiconductor
chips.
Note: No other components within the spectrometer should be touched (even with the power
off) without first contacting a Bruker service representative to obtain all necessary
instructions, to ensure user and spectrometer safety.
