Step 4: Connect the other end of the ground wire to the ground bar of the switch.
Note:
Generally, the cabinets installed in equipment rooms are equipped with ground bar. In
this case, you can connect the PGND wire of the switch to the ground bar for it.
II. Other grounding environment
Following are some methods for grounding the switch in different grounding
environments that you are likely to encounter when installing the switch at different
places.
Note:
Rather than specifying the switch model or showing the actual location of the switch
power input or grounding screw, the following figures are primarily intended for
illustrating the switch grounding, either via grounding screw or power input, in specific
grounding environments.
z If a ground bar is available, attach one end of the yellow-green PGND wire of the
switch to a grounding bolt of the ground bar and fasten the captive nuts. Note that
the fire main and lightning rod of a building are not suitable for grounding the
switch. The PGND wire of the switch should be connected to the grounding device
in the equipment room. (For the S9500 series, the grounding screw is on the rear
panel. Connect it as illustrated in Figure 4-6).
