Line Power
You are responsible for providing a power source of acceptable quality to operate the system.
The quality of line power (ac mains power system) delivered to the TSQ Endura or
TSQ Quantiva system can affect its performance and longevity. To ensure that the system performs optimally and is not damaged by line power fluctuations, verify that the lab’s electrical supply complies with all power quality requirements.
CAUTION To support compliance and safety requirements, all devices connected between the power source and the mass spectrometer must be certified by recognized organizations for your country or territory (for example, UL, CSA, SEMKO, VDE, or TÜV).
Such devices include the power supply cords, electrical outlets, circuit breakers, uninterruptible power supplies (UPSs), and so on.

Quality of Power
Quality of Power
Establishing the quality of power supplied to the LC/MS system is very important for these reasons:
• Constant high line voltage, impulses, or surges in voltage can cause overheating and component failures.
• Constant low line voltage or sags in voltage can cause the system to function erratically or not at all.
• Transients—even a few microseconds in duration—can cause electronic devices to degrade or fail catastrophically, shortening the lifetime of the system.
Before the service engineer arrives to install your system, make sure the line voltage is stable and within the recommended specifications. The line voltage must be free of fluctuations due to slow changes in the average sags, surges, transients, or voltage. For the mass spectrometer’s
electrical ratings, see Table 7 on page 17 .
Table 6 lists the definitions for the three most common voltage disturbances.
Table 6. Common voltage disturbances
Voltage disturbance
Slow average
Sags and surges
Transients or impulses
Definition
A gradual, long-term change in average root mean square
(RMS) voltage level, with typical durations greater than 2 s
Sudden changes in average RMS voltage level, with typical durations between 50 ms and 2 s
A brief voltage spike of up to several thousand volts, with typical durations up to 50 μs
Power Monitoring Devices
Several devices are available to monitor the quality of the line power. These devices provide a continuous record of line performance by analyzing and printing out data for the three most
common voltage disturbances (see Table 6 ).
In the first two cases, the time interval recording indicates the duration and the amplitude of the disturbance. A power line disturbance analyzer detects and records most types of line power problems. The Dranetz™ system
1
is an example of a suitable analyzer. In some countries, you can rent power line analyzers from electrical equipment suppliers.

Power Conditioning Devices
Monitor the power line 24 hours a day for seven consecutive days. If inspection of the printout indicates disturbances, stop the test and take corrective action. Monitor the power again as previously described.
Power Conditioning Devices
You can correct a line voltage problem by using various line voltage conditioning devices. If the power regulation is good but the power line disturbance analyzer shows transient voltages, an isolation/noise-suppression transformer can resolve the problem. For both transient and regulation problems, consider the use of power conditioners to control these problems. See
the CAUTION statement on page 13 .
CAUTION Any conditioning devices installed with the system must be able to handle the potentially high currents that are drawn during the initial startup of the system. For example, during startup, the forepump or forepumps can draw a high inrush current.
Because the TSQ Endura and TSQ Quantiva mass spectrometers require the use of one or two forepumps, the system draws an inrush current. The maximum inrush (start) current for one forepump (Oerlikon Leybold Vacuum™, model SOGEVAC™ SV 65 BI) is 12 A.
The average duration of the forepump’s inrush current is less than 1 s. Therefore, this initial energy demand from the ac power line is very low.
Thermo Scientific systems are protected from overcurrents with time-delay fuses and active switches. For more information, contact your Thermo Fisher Scientific service engineer.
When the line voltage is free from voltage sags, surges, and impulses but is more than
10 percent outside of the voltage specifications, a buck/boost transformer can lower (buck
10 percent) or raise (boost 10 percent) the line voltage as appropriate for the rated voltage.
Order the Buck/Boost Transformer Kit (P/N OPTON-01460) from Thermo Fisher Scientific
San Jose. Each buck/boost transformer is encased in a metal housing approximately
13 13 26 cm (5 5 10 in.) and ships with a 2 m (6.5 ft) power supply cable. Have a certified electrician install the transformer, using the installation instructions that are included. Then, install the TSQ Endura or TSQ Quantiva system.
CAUTION Systems installed in areas with 208 Vac power can experience voltage sags during high use periods that might place the line voltage below the operating parameters discussed in this section. In this case, protect the system by using a buck/boost transformer to ensure that power stays within the specified parameters.
Uninterruptible Power Supply
If your local area is susceptible to corrupted power or power disruptions, install an
uninterruptible power supply (UPS) in the lab. See the Caution on page 13 .

Circuit Breakers
Circuit Breakers
Make sure that each circuit breaker is suitably rated so that the equipment connected to the electrical outlets does not lose power by triggering a current overload condition. For added protection, install a surge protector at the input to the circuit breaker panel.
Earth Ground
Make sure that the earth ground connections in the lab are hardwired to the same ground used for the main circuit breaker panel. Multiple external ground points can cause noise current to flow through the ground loop that is formed.
Electrical Outlets
Installing a complete TSQ Endura or TSQ Quantiva system can require extensive electrical resources for connecting all of the equipment. Plan the power system properly, with a sufficient number of grounded, electrical outlets that are suitably rated. In addition, Thermo
Fisher Scientific recommends having several additional outlets close to the work area for testing and cleaning equipment, such as an oscilloscope and a sonicator.
CAUTION To avoid an electric shock, always have a certified electrician install any new wall receptacles.
Table 7 lists the electrical ratings (labels) and required number of outlets for the modules in a
typical lab setup. For the LC modules, refer to the manufacturer's manuals. To prevent overloading the outlets, select outlets with a load rating that is suitable for the expected total current draw per outlet.
IMPORTANT
• Thermo Fisher Scientific recommends that you connect the mass spectrometer and each forepump to separate electrical outlets that have their own dedicated single-phase, circuit breakers rated 230 Vac, 15 A for North America and 230 Vac,
16 A for other countries and territories. For example, the TSQ Quantiva system requires three separate, dedicated electrical outlets (one for the instrument and two
for the forepumps). See also Figure 2 .
• In North America, the LC/MS system requires both 120 and 230 Vac single-phase electrical outlets.

Remember to add the number of outlets required for your LC system.
IMPORTANT After planning the location of the workbenches (see
), consider the following before installing the electrical outlets:
• Each module’s location and whether each requires a 120 or 230 Vac outlet (see
• The minimum number of outlets needed for a given voltage and adding the number of outlets needed for any additional lab equipment (see
)
• The length of the power supply cords (see
