The AP200 must be earth grounded. Refer to section 7.1, ESD Protection in
the CR1000 Measurement and Control System Operator’s Manual, for
information on earth grounding and lightning protection. All component
grounds of the AP200 profile system are pre-wired at the factory to a common
ground lug located at the bottom of the enclosure. Ground this lug using
heavy-gauge copper wire. An AP200 grounded to the UT30 tower is shown in
FIGURE 5-10.
