3-4 Location
A. The Series 5900 DID GC should be placed in a location that is secure, vibration free, protected from
abrupt temperature changes (operating ambient temperature range is 15 °C - 40 °C), and drafts.
Such changes may upset the temperature stability in the course of an analysis or preparation.
B. Enough adjacent tabletop space should be allowed for the installation of computers, etc, allow
sufficent space on all sides of the GC for easy access.
C. Make sure that there is adequate space for the installation of the gas cylinders. Cylinders should be
securely fastened to an immoveable structure per CGA and/or O.S.H.A. regulations.
D. An electrical outlet (AC) should be near the location where the GC will be installed. If the outlet
is not a 3-pin type, make sure that a good ground connection is available since a good ground is
necessary for proper operation. The AC outlet should be connected to a circuit that is not heavily
loaded with other electrical equipment. Input voltage to the GC should be steady for optimum
operating stability.
If the AC line voltage varies, consideration should be given to the installation of a stabilizing
transformer at the AC outlet. An uninterruptable power supply (UPS) with surge protection is also
recommended to prevent disruption from power loss or electrical spikes.
NOTE
BOTH THE GC AND DATA INTERFACE SHOULD BE CONNECTED TO THE SAME DUPLEX SERVICE
OUTLET TO PREVENT GROUND LOOPS.

Power Requirements
A. The Series 5900 DID GC requires a 120 volt/50-60 Hz power source with a minimum of 15 amps.
B. The Series 5902 DID GC requires a 240 volt/50-60 Hz power source with a minimum of 10 amps.
C. The AC power cord is terminated with a straight-blade 3-prong plug rated for 15 amp service that
requires a matching receptacle.
