3-14z Apply magnet mounting to only the above two models. Otherwise, a falloff or mis-operation mayoccur.z Select the installation location carefully. In the case of poor surface, magnet mounting may not bereliable.z Put the device at a stable place free from vibrations or shocks. Otherwise, personal injuries orequipment damage may occur.z Avoid installing the device at a high place because personal injuries or equipment damage mayoccur in case of a falloff.z Avoid frequently moving the desk-mounted device because such movements may damage thesurface coating.z Keep the front panel of the device facing downwards and the two sides with ventilation holesvertical to the ground, if you want to install the device vertically.z Pay attention that the weight of external cables should not bring about a falloff, which may result inpersonal injuries or equipment damage.z Keep floppy disks and magnetic cards away from magnets to avoid erasure of any information.z Keep computers and monitors that are easily influenced by magnetic fields away from magnets.Otherwise, faults may occur to these electronic devices.Connecting Grounding Cablez Correctly connecting the switch ground wire is crucial to the lightning protection andelectromagnetic susceptibility (EMS) of a switch.z The power and grounding terminals in this section are for illustration only.The power input end of the switch is connected with a noise filter, whose central ground is directlyconnected to the chassis, forming the so-called chassis ground (commonly known as PGND). Thischassis ground must be securely connected to the earth so that the faradism and leakage electricity canbe safely released to the earth, enhancing the EMS capability of the switch.When a Grounding Strip is AvailableWhen a grounding strip is available at the installation site, attach one end of the yellow-green groundwire of the switch to the grounding screw on the grounding strip (the grounding screw and the groundinghole are on the rear panel of the switch and are marked with a grounding sign). To do this, follow thesesteps:Step 1: Remove the grounding screw from the rear panel of the switch chassis.Step 2: Put the supplied OT terminal of the PGND cable on the grounding screw.
