This topic describes the grounding principle of the N63E-22 cabinet and the position of the ground point.

Connect the ground cables properly to guarantee protection against lightening and interference for the N63E-22 cabinet.

The power input end of the N63E-22 cabinet has a noise filter. The center ground of the noise filter connects to the cabinet, called the cabinet ground, that is, the protection ground. Ground the cabinet securely so that the influence electricity, leakage electricity can flow to the ground, improving the protection against electromagnetic interference.

Use a ground cable to connect the ground point of the cabinet to the ground bar of the telecommunications room or to the ground directly. It is recommended that the grounding resistance of the telecommunications room should be less than 10 ohms. Refer to the local standards to ground the cabinet.

The ground point of the cabinet is on the top of the cabinet, as shown in Figure 1-15.
