2.3.1 Proper Equipment Grounding
WARNING!
Hazardous voltages that could seriously in-
jure or cause death are present in many vacuum processes. Ver-
ify that the vacuum port on which the XGS-321 vacuum gauge
tube is mounted is electrically grounded. Consult a qualified
Electrician if you are in doubt about your equipment grounding.
Proper grounding of your equipment is essential for safety as
well as intended operation of the equipment. The XGS-321
vacuum gauge tube and enclosure of the XGC-320 controller
must be connected directly to a good quality earth ground. Use a
ground lug on the XGS-321 gauge vacuum connection / flange if
necessary.
WARNING!
In order to protect personnel from electric
shock and bodily harm, shield all conductors which are sub-
ject to potential high voltage electrical discharges in or
around the vacuum system.
