Connecting to Power
Connecting an NV8144 router frame to power is fairly simple. The router frame is connected to a
15A AC power source sufficient to power the PS8100 modules installed in the frame.
Connecting an NV8140 frame to power is nearly as simple. The NV8140 frame has two C19
power connectors and requires connection 20A plant lines. The cable supplied in North America
has a NEMA L5-20P connector at the other end. For customers outside North America, we ship
these power cords with the NEMA end cut off.
For the NV8280, NV8576, and NV8576-Plus that require an external NV8300 power supply frame,
additional power connections and precautions are required. In addition, power supply moni-
toring and alarm connections can be made.
The NV8300 power supply frame has two DB25 connectors located at the rear. The connector
labeled
Power Supply Monitor
carries alarm and temperature signals to the router. The router,
through its control card, sends this information to the router control system.
The other connector, labeled
Alarms
, presents isolated alarm signals that can be connected to
an external alarm indicator. See
Alarms
on page 109.
Recommended Protections
The following recommendations are not necessary for connecting a router to a power source,
but are strongly encouraged:
•
Connect to separate branch circuits.
For added protection in a main power failure, connect the main and redundant power
source connections to the NV8300 power supply frame be connected to different branch cir-
cuits.
•
Label the line-side power connection (near your facility’s power outlets).
Accidental disconnection of router power at the outlets can cause a disruption in your on-air
signals.
Normally to remove power from an NV8140 or NV8144, you pull its power cords.
Normally to remove power from an NV8280, NV8576, or NV8576-Plus, you pull the PS8300s
out of the NV8300 power supply frame, one by one.
Note:
For the NV8576-Plus, there are 8 or 16 PS8300s to pull out. This takes a significant
amount of time.
•
Connect the ground lug to earth ground.
Each router has a ground lug on the back of the frame. You should connect the ground lug
to earth ground. Failure to connect the ground does not affect normal operation. However,
grounding helps protect you and your equipment in case of a power anomaly such as a
lightning strike.
