Step 2: Directly insert the connector into DC-input socket on the cabinet, and then fix
the screws 1 and 2 carried by the connector itself to the appropriate holes on the
cabinet socket using a small flathead screwdriver, see Figure 3-13.

The length of the DC power cord must be less than 3 m (9.8 ft.).

3.2.3 Connecting the Ground Wire

Caution:
Correctly connecting the switch ground wire is crucial to the lightning protection and
electromagnetic susceptibility (EMS) of a switch.
The power input end of the switch is connected with a noise filter, whose central ground
is directly connected to the chassis, forming the chassis ground (commonly known as
PGND). This chassis ground must be securely connected to the earth ground so that
the faradism and leakage electricity can be safely released to the ground, enhancing
the EMS capability of the switch.
