7.0 Earth-ground the ACU2 (v2)
ASTi does not require the ACU2 (v2) to be grounded. However, it was designed to accom-
modate customers with strict grounding policies and requirements. To reduce resistance, keep
your grounding wire as short as possible. This practice effectively dissipates an unwanted
electrical charge.
The following equipment is required:
l
#10 grounding ring connector
l
Ground wire (i.e., stranded, braided, or strap wire; 18 gauge American wire gauge
(AWG) minimum)
Figure 21: Grounding
Important : Do not remove nut #1 from the screw as it will cause the screw to fall inside the
ACU2 (v2) chassis.
To ground the ACU2 (v2), follow these steps:
1. Remove nut #2.
2. Slip the grounding ring connector onto the threaded end of the jackscrew.
3. Insert nut #2 onto the threaded end of the jack screw. Take care not to cross thread or
over-tighten the nut when reattaching.
