• Use the power supply equipped with an earth leakage breaker. Use of power
supply without such a breaker could result in re if there is a current leakage.
• Have available a securely grounded indoor ground terminal. Without proper
grounding, customers could be electrocuted and product operations might not
always be stable.
• Do not expose the power cord or ground wire. If these are exposed, customers
could stumble over them, for instance, and easily damage them. Additionally, if
these lines are damaged, there could be a risk of electrical shock or short circuit.
Set these lines at locations where they will not interfere with customer trafc, or
attach covers to them.
• After laying out the power cord on the floor, be sure to always protect it. If
the power cord is left exposed, it can easily be damaged, resulting in electrical
shock.
