z
Apply magnet mounting to only the above two models. Otherwise, a falloff or mis-operation may
occur.
z
Select the installation location carefully. In the case of poor surface, magnet mounting may not be
reliable.
z
Put the device at a stable place free from vibrations or shocks. Otherwise, personal injuries or
equipment damage may occur.
z
Avoid installing the device at a high place because personal injuries or equipment damage may
occur in case of a falloff.
z
Avoid frequently moving the desk-mounted device because such movements may damage the
surface coating.
z
Keep the front panel of the device facing downwards and the two sides with ventilation holes
vertical 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 in
personal 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 Cable
z
Correctly connecting the switch ground wire is crucial to the lightning protection and
electromagnetic 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 directly
connected to the chassis, forming the so-called chassis ground (commonly known as PGND). This
chassis ground must be securely connected to the earth so that the faradism and leakage electricity can
be safely released to the earth, enhancing the EMS capability of the switch.
When a Grounding Strip is Available
When a grounding strip is available at the installation site, attach one end of the yellow-green ground
wire of the switch to the grounding screw on the grounding strip (the grounding screw and the grounding
hole are on the rear panel of the switch and are marked with a grounding sign). To do this, follow these
steps:
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.
