If other devices are to be powered from the same isolated power supply that is
powering the NGC, be careful to avoid any ground loops. The various devices
should be connected in a star configuration. It is also important that any additional
powered devices be able to handle a fairly wide range of input voltages, as the
NGC’s heater will draw about 4 amps (if the auxiliary heater is installed, it might be
as much as 8 amps). This load (4-8 amps) being drawn across any considerable
length of cable can result in a substantial voltage drop (Please refer to Cable
Length Power Specifications table). The resulting lower input voltage to the
additional device could effect its operation. Input voltage excursions fluctuate with
the toggling of the NGC’s heater(s). The heater(s) are turning on and off in an
effort to maintain a very constant internal temperature for the NGC’s GC module.
In an office environment, insure that a good earth ground is established to the
NGC8206. In an office situation, it is easy to not have the NGC well grounded.
Often the third pin (ground) on the power cable is missing or has been removed.
Improper grounding can lead to erratic behavior. Be sure that the unit is properly
grounded. If the unit is not properly grounded, the user could have as much as
60VAC (half line voltage) on the case of the equipment due to capacitive coupling
within the power supply.
