Power and Grounding
! 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.
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.
