Miscellaneous Procedures and Instructions
equipment, we recommend a separate dedicated power source for their
operation.
NOTE: Do not use the free outlet for equipment that draws more than 2 amps.

NOTE: Avoid using power supplies from sources that may be subject to RF
interference, such as electric motors and elevators.
Care must be taken to ensure that sources of radio frequency interference (RFI)
and electromagnetic interference (EMI) are not placed on the same power line, or
share the same ground plane, since this can degrade the performance of the GC.
Equipment such as motors, solenoids, fluorescent light fixtures, and radio
communication transmitters should be isolated from the instrument and
connecting cables as much as possible.
The power cable from the GC is approximately 2m (6 ft) long and fitted with
National Electronics Manufacturers Association (NEMA) 5-20P power plugs. The
NEMA 5-20P power plug and corresponding outlet are shown in Figure (a).
NEMA 5-20P plugs are rated at 20A and 120 Vac.
The power cable from the mass spectrometer is approximately 2.5m (8 ft) long
and fitted with US Standard National Electronics Manufacturers Association
(NEMA) 5-15P power plugs. The NEMA 5-15P power plug and corresponding
outlet are shown in Figure (b). NEMA 5-15P plugs are rated at 15A and 120 Vac.
Systems shipped outside the United States and Canada are fitted with CEE 7/7
plugs; these are rated at 16A and 230 Vac. The CEE 7/7 plug and outlet are
shown in Figure (c).
The power cables for the computer, monitor, and printer are approximately 2m
(6 ft) long. They are fitted with NEMA 5-15P plugs. The power cable from the
8200 AutoSampler is about 2m (6 ft) long, and is fitted with a NEMA 5-15P plug
rated at 120V.
