?在門和外殼之間安裝連接線，以實(shí)現(xiàn)電氣接觸；不要依賴鉸鏈將接地母線連接到接地極系統(tǒng)地極系統(tǒng)處于地電位，是中心任何設(shè)施內(nèi)所有電氣設(shè)備和交流電源的接地。使用接地電極導(dǎo)體，用于將接地母線連接到接地極系統(tǒng)。至少使用8.3 mm2（8 AWG）銅線防止電磁干擾的接地極導(dǎo)體。
?
use 2.54 cm (1in) copper braid or 5.2 mm2 (10 AWG) copper wire to connect each chassis, the
enclosure, and a central ground bus mounted on the back-panel
?
use a steel enclosure to guard against electromagnetic interference (EMI)
?
make sure the enclosure door viewing window is a laminated screen or a conductive optical substrate
(to block EMI)
?
install a bonding wire for electrical contact between the door and the enclosure; do not rely on the
hinge
Connect Ground Bus to Grounding-Electrode System
The grounding-electrode system is at earth-ground potential and is the central
ground for all electrical equipment and ac power within any facility. Use a
grounding-electrode conductor to connect the ground bus to the
grounding-electrode system. Use at minimum 8.3 mm2 (8 AWG) copper wire for
the grounding-electrode conductor to guard against EMI. The National Electrical
Code specifies safety requirements for the grounding-electrode conductor.
