Requirements for power outlets
¢
Use a grounding 2-pole plug-in power outlet. Outlets of any other
types would cause an electric shock or fire.
¢
In order to prevent an electric shock, connect the outlet's grounding
electrode to a grounding terminal installed by a qualified electrician.
Without connection to the grounding terminal, an electric shock can
occur in the event of a failure in power supply modules.
Plugging and unplugging
When inserting the power plug into the electrical outlet or removing it, be
sure to hold the plug section. Do not pull the cable; it can partially break
the wire, overheat the broken part and lead to a fire.
Power supply module
Since the power supply module has a high-voltage area in it, do not open
the cover. If you do, it can result in an electric shock or equipment
failure.
Installing power supply slot cover
When removing a power supply module, do not insert your hand or tool
inside the power slot. After removing a power supply module, install a
power slot cover. Inside the power slot, some conductors are exposed. If
you touch them with your hand or tool, it may cause electric shock or
equipment failure.
Abnormal heat, smoke, abnormal noise, or abnormal smell
Should you find anything abnormal occurring, turn off the power and
unplug all the power cords of the equipment (maximum of 4) from the
electrical outlets.
Removal of the cover or bracket
Do not remove the cover or bracket. It can result in an electric shock,
burns or equipment failure.
