Usually, the routerwill be installed on a clean workbench. The operations are very simple, but still, youshould be aware of the following items:• Ensure the stability and well-grounding of the workbench.• Leave a space of 10cm around the router for heat dissipation.• Do not place heavy objects on the router.4.3 Connecting the PGND WireWarning:The normal connection of the PGND wire is an important guard against the lightning and interference.Therefore, the user must first correctly connect the PGND wire before installing and using the device.The power input end of Quidway AR 28 Series Router is connected to a noise filter. Theneutral point of the noise filter is directly connected to the chassis and is calledprotection ground (PGND). The PGND wire must be well grounded, so as to safelyconduct the faradism and leaky electricity to the earth ground, and thereby improve thecapability of the whole device to guard against the electromagnetic interference. ThisPGND wire can also protect the router against the lightning caused by the connectionwith the external network lines, such as E1/T1 line, ISDN/PSTN line.The grounding screw of Quidway AR 28 Series Router, which is marked with groundinglabel, is located near the AC power socket and its switch on the rear pannel of thechassis, as shown in the following figure:Power switch AC input Grounding screwFigure 4-5 Grounding screw of the router4-5
