Safety Considerations - NEC Univerge sv8500 Manual

2. SAFETY CONSIDERATIONS

The following describes the safety considerations that must be observed before using the system, the power-
related equipment and the peripheral equipment, such as consoles, the Main Distribution Frame (MDF),
telephones, PCs, printers, etc.
If the system emits smoke or a burning, acrid odor, immediately turn off the system power.
Operating the system in this state might cause a fire, an electrical shock, or a system failure. After
turning off the power and confirming that the smoke has disappeared, contact the dealer.
If any equipment, such as the system, the main power source, a cabinet or peripheral equipment tips
over, turn off the power and contact the dealer.
If liquid reaches the inside of the system or the main power source, turn off the power. Operating
the system in this state might cause a fire, an electrical shock, or a system failure.
Do not touch the internal parts of the main power source to disassemble or configure it. This action
may cause a fire, an electrical shock or a system failure.
NEC Corporation does not take any responsibility for disassembled or reconfigured equipment.
Do not put any container objects (such as a vase or a cup) on the main power source or any
peripheral equipment. It might cause a fire, an electrical shock or a system failure.
Be sure to use cables designated by NEC or cables attached to the equipment. If cables are not
designated particularly, choose cables with considering safety and transmission performance
carefully. Ask the dealer or your local agency if needed.
Do not tamper with, modify, forcefully bend, forcefully remove or twist an electrical cord or any
wiring to or from the system, the main power source or any peripheral equipment. It might cause a
fire, an electrical shock, or a system failure. If the wiring is damaged, contact the dealer.
Correctly insert all of the electrical plugs into the electrical outlets. Before inserting a plug into an
dust
electrical outlet, ensure that there is no dust on the plug's blades. If there is dust on a blade, it might
cause a fire.
