2.7 Cables

2.7.1 Ground cable

Connecting the ground cable properly is an important guarantee for lightning
protection, anti-electric shock, and anti-interference. The Gazelle S1020i-LI must be
connected to the ground cable correctly during installation, which helps avoid
personal injury and equipment damage.
There is a ground terminal on the front panel of the Gazelle S1020i-LI, namely, the chassis
GND. Use the ground terminal to fasten one end of the ground cable to the ground point on
the chassis, and connect the other end to the ground.
Appearance
The ground cable is composed of the ground terminal and conductive wire. In general, the
ground terminal is an OT bare-pressure terminal; and the conductive wire is a yellow/green
copper soft flame-retardant conducting wire.
Figure 2-10 shows the ground cable. Figure 2-11 shows the OT terminal.
