• Ensure that all surfaces, including the floor, are dry when using the
system.
• Make sure that the main power switch of the system is easily accessible.
• If the analyzer needs to be opened for calibration, maintenance, repair,
or replacement (e.g., of fuses), switch off the analyzer and disconnect it
from all voltage sources as described in the relevant procedure. If any
calibration, maintenance or repair work has to be carried out on the open
analyzer while it is connected to a mains power source, this may only be
performed by a specialist who is familiar with the dangers associated
with such action.
• Only use replacement fuses of the specified type and current rating.
• Only use fuses in perfect technical order.
• Never short-circuit the fuse holder.
Risk of short-circuit by spilled liquids that can come into contact with live
parts. Damage to the system can result. To avoid this hazard:
• Never pour liquids or place containers with liquid on top of the system.
• Disconnect the main plug immediately if liquid is spilled into the system.
Risk of malfunctions in nearby electrical devices due to radio interference.
In a domestic environment, it can cause radio interference. To avoid this
hazard:
• Assess the electromagnetic environment prior to operating the analyzer.
• Use the cables supplied.
• Use shielded cables and plugs if external devices are connected, for
example, a printer or a network.
Risk of malfunctions of the system such as false results due to radio
interference by other electrical devices. To avoid this hazard:
• Do not operate strong electromagnetic transmitters, for example, mobile
phones, walkie-talkies, door openers, or elevators, in the vicinity of the
system.
• In places where the quality of the power supply line is poor or impacted
by other electrical devices, consider the use of an external UPS.
2.2.3 Mechanical safety
Risk of injury by moving parts. To avoid this hazard:
• Do not touch the carousel while the measurement is in progress.
• Never bypass or remove safety devices, for example, cover switches.
• Never open or remove the cover whilst the analyzer is in operation. The
cover may only be opened by Siemens service.
• Keep clear of moving parts when the system is in operation. Long hair,
necklaces, bracelets, and similar objects can get caught in moving parts.
