3.7 Connect an additional RF earth (ground) (optional)
If the dry pumping system will be operated in an area subject to high Radio Frequency (RF) emissions, in accordance
with good RF installation practice, Edwards recommend:
Use a star washer to connect the end of the Earth (ground) cable (Figure 2, item 6) connected to the dry
pumping system inlet to one of the bolts that are used to secure the inlet flange.
Connect an additional Earth (ground) cable to the RF Earth (ground) stud (Figure 3, item 19). A suitable low-
impedance cable must be used (for example, use braided cable).
