Available Outlets
The TSQ Quantum XLS and TSQ Quantum GC mass spectrometers are designed to operate
at a nominal voltage of 230 V ac, 50/60 Hz. Line voltages can vary between a minimum of
207 V ac and a maximum of 253 V ac.
The minimum and maximum voltage tolerances are in compliance with IEC 950, Amend 2,
1993, paragraph 1.6.5, as follows:
“Equipment intended to operate directly from the main supply shall be designed for a
minimum supply tolerance of +6% and -10%. If the rated voltage is 230 V ac single
phase or 400 V ac three phase, the equipment shall operate safely within a minimum
supply tolerance of ±10%.”
For systems installed in regions with both 120 V ac and 230 V ac service, the basic power
requirements for a TSQ Quantum XLS or TSQ Quantum GC system consist of the
following:
• Nominal voltage of 120 V ac, +6 to –10% and 230 V ac, ±10% and free from voltage
variations above or below this operating range.
• Frequency of 50/60 Hz.
• One fourplex outlet (single-phase power, NEMA 20-5 receptacles) with a minimum
power rating of 20 A (120 V ac).
• One single outlet (single-phase power) with a minimum power rating of 30 A (230 V ac).
• Earth ground hard wired to the main panel.
For systems installed in areas with 230 V ac only service, the basic power requirements for a
TSQ Quantum XLS or TSQ Quantum GC system consist of the following:
• Nominal voltage of 230 V ac, ±10%.
• Frequency of 50/60 Hz.
• One fourplex outlet (NEMA 20-5 receptacles), with a minimum power rating of 20 A.
(In the United States, with only 15 and 20 A power rating options are available, you must
choose the 20 A option.)
• One single outlet (single-phase power) with a minimum power rating of 30 A (230 V ac).
• Earth ground hardwired to the main panel.
CAUTION Systems installed in areas with 208 V power experience voltage sags during
high use periods that might place the line voltage below the operating parameters
discussed in this section. In this case, you must protect your instrument by using a
buck/boost transformer to ensure that power is within the specified parameters at all
times.
