3 Installing the Base Station
Base Station User Guide 27
We recommend that proper AC line conditioning and surge suppression be provided on
the primary AC input to the power amplifier. All electrical service should be installed
with your national electrical code in your area, any applicable provincial or state codes,
and good engineering practice. Special consideration should be given to lightning
protection of all systems in view of the vulnerability of most transmitter sites to lightning.
Lightning arrestors are recommended in the service entrance. Straight and short
grounds are recommended. The electrical service must be well grounded. Do not
connect the unit to an open delta primary power supply, as voltage fluctuations could
harm the unit. Branch your circuits. Do not allow your lights, your workbench plugs, and
your transmitting equipment to operate on one circuit breaker. Each transmitter should
have its own circuit breaker, so a failure in one does not shut off the whole installation.
Shelter Security
The FCC requires that the transmitter be secure from entry or control by unauthorized
persons, and that any hazardous voltages or other dangers, including most tower
bases, be protected by locks or fences as necessary to protect personnel and prevent
unauthorized tampering or operation. Security of the building further implies that it be
secure from wildlife. Use sturdy construction materials, including sheet metal if
necessary. Holes around conduit, cable, and other similar entry points should be stuffed
with steel wool and caulked to prevent entry of wildlife. Other features of security for
your shelter may include its location with respect to the prevailing wind conditions. A
location leeward of some natural topographical feature will prevent wind damage and
snowdrifts. Check the soil runoff conditions that may slow or hasten wind or water
erosion and other concerns that may be unique to your location.
Unpacking and Inspection
Check the outside of the container. Carefully open the container and remove the
contents. Retain all packing material that can be reassembled in the event that the
equipment must be returned to the factory.
; Note: Exercise care in handling equipment during inspection to prevent damage due to
rough or careless handling.
Visually inspect the contents for damage that may have occurred during shipment.
Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or
extraneous packing material in connectors or fan failures. Inspect all connectors for
bent connector pins. If the equipment is damaged, a claim should be filed with the
carrier once the extent of the damage is assessed.
