Chapter 6 Grounding
Grounding is absolutely necessary to protect the operators and maintenance personnel
from electric shock and prevent equipment malfunction.
Warning
• Before starting grounding, make sure that power has been switched off. Otherwise, there is
the danger of electric shock.
Caution
• Work gloves are recommended to protect yourself from injuries with angular parts of the
product.
• Static might cause the product to fail. Discharge the static from the human body before start-
ing your work.
• Never touch any other parts than those necessary for performing the work.
• Be careful not to lose the screws and parts removed from the product. Do not drop them
inside the product.
• In using a screwdriver, make sure that it fits the screw to be tightened or loosened. Use of
an unfit screwdriver will not only adversely affect work efficiency but also cause possible
damage to the slots in the screw head.
