4.1 Ground cable

4.1.1 Introduction

Connecting the ground cable properly is an important guarantee for lightning
protection, shock proof, and anti-interference. When installing and using the device,
ensure that the ground cable is properly connected; otherwise, personnel injury or
equipment damage may occur.

The ground cable is used to connect the Gazelle S1512i-PWR to the ground.

4.1.2 Appearance

The ground cable is composed of ground terminals and the coaxial cable. The ground terminal
is usually an OT non-insulated terminal. The coaxial cable is a

yellow/green copper soft

flame-retardant conducting wire. Figure 4-1 and 0 show the ground cable and OT terminal.
