Technically Qualified Personnel Only
WARNING: Installation and servicing should only be done by BRUKER qualified personnel.
Always disconnect power cables before servicing. Under certain conditions dangerous
voltages may exist even with the power cables removed. To avoid injuries, always disconnect
power and discharge circuits before touching them.
NOTE: Operating personnel must not remove chassis covers except as described in this
manual. Do not replace BSMS/2 units with mains switch turned on. User interface, system
messages, and manuals require a good understanding of the English language.
Electrical Safety
The BSMS/2 systems degree of protection against electrical hazard complies with IEC
61010-1, i.e. all electrical parts are protected against touching.
WARNING: All electrical connectors must be used as supplied by BRUKER. Do not substitute
them by other types.
Lifting the BSMS/2 Chassis
WARNING: At least two people are needed to insert and remove the BSMS/2 chassis from
the electronics cabinet. A fully equipped BSMS/2 system can weight more than 50 kg.
NOTE: Remove some or all of the BSMS/2 units from the chassis prior to handling to reduce
weight.
Cleaning
WARNING: Always switch power off and disconnect the power cable before cleaning. Never
power on until all surfaces are completely dry.
Clean the outside of the BSMS/2 chassis and units with a soft, lint-free cloth dampened in
water. Do not use any detergent or other cleaning solvents.
3.6 Transmitter Safety
Signals of relatively large amplitude are often required to excite the NMR sample and hence
the need for transmitters (also known as amplifiers). Transmitters can be internal
(incorporated into the AQS rack) or external (separate standalone units). Cables running
directly from the amplifier outputs to the HPPR carry the RF signal to the sample.
The RF signal leaving the amplifier can be of the order of several hundred volts and is not
recommended to be viewed on the scope without attenuation.
3.6.1 Transmitter Safety
Bruker amplifiers are built in accordance with the standard 61010-1 Safety Requirements for
Electrical Equipment.
