Mains Supply Fluctuations

Return to
checklist.
In areas where the mains supply is subject to voltage fluctuations exceeding 5% of the nominal value (200 VAC
to 240 VAC), a power conditioner is required. High or low voltages can adversely affect the electronic components
of the mass spectrometer. Refer to
20.
Note: Peripheral devices might have different mains supply fluctuation limits. Confirm the mains supply fluctuation
limit with the vendor of each peripheral device that will be used with the mass spectrometer.

Protective Earth Conductor

Return to
checklist.
WARNING! Electrical Shock Hazard: Do not intentionally interrupt the protective
earth conductor. Any interruption of the protective earth conductor is likely to make
the installation dangerous.
The mains supply must include a correctly installed protective earth conductor that must be installed or checked
by a qualified electrician before connecting the mass spectrometer.

Uninterruptible Power Supply or Power Conditioner

Return to
checklist.
Use a pure sine-wave uninterruptible power supply (UPS) or power conditioner to maintain the system supply
(mass spectrometer, computer, monitor, and roughing pump) during power outages.
If the system is powered by a UPS or power conditioner, then it must meet the following specifications.
