Important Safety Information 87 WARNING: The system must be installed in a secure (locked) area. The components and telephones of the NBX system are electronic devices. To avoid injury and damage to the equipment, follow these important safety precautions when you install, use, or service it: ■ Allow only qualified personnel to install and remove the unit. ■ Always connect the unit to a grounded (protective earthed) outlet to comply with international safety and EMC standards. ■ Read and understand all instructions. ■ Always disconnect a device from its power source before you clean it. CAUTION: Each of the two power supply units in a V3001R or a V5000 with redundant power supplies has its own overcurrent protection device which operates independently - the overcurrent device for one power supply does not protect the second power supply. You must connect both AC power cords to provide power to both of the power supplies. Disconnect all power inputs to power off the device. ■ Do not disassemble components of the system. If you suspect that a card, chassis, or telephone is defective, call a service representative. ■ Do not use this product near water. Do not install this product or a telephone in a damp area, such as a basement. ■ Never cover or block the ventilation holes on the chassis or telephones. Proper ventilation is required to ensure normal operation of each component and to avoid component failures. ■ WARNING: Never push objects into ventilation holes on the chassis or telephone. Electrical voltages in system components can cause bodily harm. ■ Do not use the telephone during an electrical storm. Lightning poses a remote risk of electric shock through any telephone system. ■ Never use a telephone that is near the source of a gas leak to report the leak. ■ Each NBX system and chassis is equipped with a three-prong grounding plug. Do not defeat the protection offered by the plug by clipping the grounding prong or by using an adapter to connect the system to a two-wire power source. ■ Do not staple the power cord or otherwise attach it to building surfaces.

Important Safety Information
87
WARNING:
The system must be installed in a secure (locked) area.
The components and telephones of the NBX system are electronic
devices. To avoid injury and damage to the equipment, follow these
important safety precautions when you install, use, or service it:
■
Allow only qualified personnel to install and remove the unit.
■
Always connect the unit to a grounded (protective earthed) outlet to
comply with international safety and EMC standards.
■
Read and understand all instructions.
■
Always disconnect a device from its power source before you clean it.
CAUTION:
Each of the two power supply units in a V3001R or a V5000
with redundant power supplies has its own overcurrent protection device
which operates independently — the overcurrent device for one power
supply does not protect the second power supply. You must connect both
AC power cords to provide power to both of the power supplies.
Disconnect all power inputs to power off the device.
■
Do not disassemble components of the system. If you suspect that a
card, chassis, or telephone is defective, call a service representative.
■
Do not use this product near water. Do not install this product or a
telephone in a damp area, such as a basement.
■
Never cover or block the ventilation holes on the chassis or
telephones. Proper ventilation is required to ensure normal operation
of each component and to avoid component failures.
■
WARNING:
Never push objects into ventilation holes on the chassis or
telephone. Electrical voltages in system components can cause bodily
harm.
■
Do not use the telephone during an electrical storm. Lightning poses
a remote risk of electric shock through any telephone system.
■
Never use a telephone that is near the source of a gas leak to report
the leak.
■
Each NBX system and chassis is equipped with a three-prong
grounding plug. Do not defeat the protection offered by the plug by
clipping the grounding prong or by using an adapter to connect the
system to a two-wire power source.
■
Do not staple the power cord or otherwise attach it to building
surfaces.
