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.
This product must be grounded. In the event of a short circuit, grounding reduces the risk of electrical shock
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 electrical connection 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. For details and 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 DataMetro II 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.
