PRODUCT COMPATIBILITY
While every effort has been made to verify operation of this product with many different communications products and
networks, P-Com Corporation makes no claim of compatibility between its products and other vendors’ equipment. It is
assumed that users have thoroughly evaluated this product’s performance in the communications environment in which
it will be used.
SAFETY
The following general safety precautions must be observed during all phases of operation and service of this product.
Failure to comply with these precautions or with specific warnings elsewhere in this Manual willfully violates standards
of design, manufacture, and intended use of the product. P-Com Corporation assumes no liability for the customer’s
failure to comply with these requirements.
Thisproduct must begrounded. Inthe event of ashort circuit,grounding reduces the risk of electricalshock by providing
an escape wire for the current.
We recommend that you use preferred power—a dedicated power circuit with an assigned circuit breaker.
The product’s AC power cord ends in a three-pole grounding plug. Do not use a three-pole to two-pole adapter with the
plug. Verify that the outlet you intend to use is properly installed and grounded; the outlet used must comply with the
National Electric Code (NEC) NFPA70 (1990) in U.S.A. or other local and national or international applicable code.
Do not install or operate this product in the presence of flammable gases or fumes. Operation of any electrical instrument
in such an environment constitutes a definite safety hazard.
No user maintained or adjustable components are present within this product. Do NOT attempt to open this unit. Do not
attempt to service this unit except under the direction of Customer Service. Only P-Com-authorized service personnel
should service this equipment. The potential for electrical shock exists within the enclosures at all times unless they are
unplugged.
Do not install substitute parts or perform any unauthorized modification to the product. Return the product to the factory
for service and repair to ensure that safety features are maintained. Prior to returning any product(s) for repair, contact P-
Com at the telephone numbers or address located in this Manual, and obtain a Return Material Authorization (RMA)
number.
Changes or modifications not expressly approved by P-Com Corporation can void the user’s authority to operate this
equipment.
SYSTEM GROUNDING
Direct grounding of the antenna, mast, and tower serves as protection from lightning strikes and static buildup. A direct
electricalconnection should be made to a suitable grounding rod at the base of the tower or mast using at least #10 AWG
ground wire, or its equivalent, and non-corrosive hardware. Fordetailsand safety standards,consult the appropriate local
Electrical Codes or a similar document. Use lightning arresters in appropriate places.
TOWER CONSTRUCTION
Compliance with local zoning and tower construction regulations is recommended when AirPro Gold®systems require a
tower. These regulations generally mandate that permits be obtained before any tower construction begins. Check with
local zoning and aviation authorities for more information.
