Power And Grounding - Lucent Technologies MERLIN LEGEND Release 5.0 Pocket Reference

!
CAUTION
For the control unit, do not use an AC outlet that is controlled by a wall
switch or some other switch.
Use an approved ground (AC receptacle for 3-prong plug).
Do not install the control unit outdoors.
Do not place the control unit near extreme heat (furnaces, heaters,
attics, or direct sunlight).
Do not expose the control unit to devices that generate electrical
interference (such as arc welders or motors).
Do not place anything on top of carriers.
Do not install the control unit under any device that may drip fluid, such
as an air conditioner.
Each auxiliary power unit requires one outlet.
Do not expose the control unit to moisture, corrosive gases, dust,
chemicals, spray paint, or similar materials.

Power and Grounding

Proper power and grounding are essential for correct and safe functioning
of the system.
Power Specifications
The system control unit plugs into a 117-VAC outlet. To avoid accidental
disconnection of the system, this outlet should not be controlled by a wall
switch.
Each carrier unit requires its own power supply. Each power supply
requires a maximum current of 5.4 amps. Therefore, if expansion carrier
units are added to the system, extra AC outlets may be needed.
Grounding Requirements
Proper grounding of the installation site protects the system against the
following:
Lightning
Power surges
Power crosses on outside lines/trunks
Electrostatic discharge (ESD)
The local telephone company is responsible for providing protection of
outside lines/trunks at the entrance to the site. The protection should
consist of the following:
Carbon blocks or gas discharge tubes connected to an approved ground
Adequate bonding of the outside line/trunk protector ground and the
power company ground
!
WARNING
An improper ground can result in equipment failures and service outages.
Verify that the AC power uses an approved ground for its primary ground,
that all voltage-limiting devices are grounded to an approved ground, and
that the ground is one of the approved grounds listed below.
