Connection in Other Grounding Environments

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.
When a grounding strip is available at the installation site, attach one end of the yellow-green
PGND cable of the switch to the grounding screw on the grounding strip and fasten the grounding
screw.
The fire main and the lightning rod of the building are not good grounding options. The PGND cable of
the switch should be connected to the earthing system of the equipment room.
