2.1 Safety Precautions
•
Installation, operation, and maintenance of the Pearl Gateway must only be performed by a
trained person who is aware of all hazards involved.
•
The Pearl Gateway must be installed in a restricted access location (such that touching of
the Gateway by untrained persons is not likely).
•
The Pearl Gateway may become hot to the touch during normal operation at elevated
ambient temperatures. The surface temperature of the enclosure may reach 90°C.
•
The Pearl Gateway has no internal field serviceable parts. The Gateway module must only
be opened by an approved service center.
•
All installation practices must be in accordance with local and national electrical codes.
•
Do not work on the system during periods of lightning activity.
•
The Pearl Gateway is considered permanently connected equipment. The Protective Earth
Ground connection to chassis is always required.
•
Ensure the Pearl Gateway Protective Earth Ground connection is properly terminated prior
to the connection of any other interfaces.
•
The Pearl Gateway TTU contains primary lightning surge suppression on the RF ports. The
primary lightning protectors have the ability to shunt lightning energy to earth ground
which includes the chassis. Ensure that the Protective Earth Ground connection is always in
place.
•
Ensure that the Pearl Gateway including the TTU and its antennas and supporting structures
are properly secured to eliminate any physical hazard to people or property. The Gateway
including the TTU must be securely mounted according to the mounting instructions prior to
any cable connection and operation.

The Pearl Gateway does not contain a power supply disconnection device; a readily
accessible disconnection device must be incorporated external to the Gateway.
•
The Pearl Gateway shall be supplied through an input overcurrent protection device rated
not more than 20 A. The overcurrent protection must have the appropriate current
interrupt capacity for the power source and must be incorporated into the non-earthed
conductor(s) of the DC supply.
