2.1 Safety Precautions
•
The Kona Micro Outdoor Gateway must be installed in a restricted access location (such
that touching of the Gateway by non-service persons is not likely).
•
The Kona Micro Outdoor Gateway may become hot to the touch during normal operation at
elevated ambient temperatures.
•
The Kona Micro Outdoor Gateway has no internal field serviceable parts. The Gateway
module must only be opened by an approved TEKTELIC service center.
•
All installation practices must be in accordance with the local and national electrical codes.
• Do not work on the system during periods of lightning activity.
•
The Kona Micro Outdoor Gateway is considered permanently connected equipment. The
Protective Earth Ground connection (that is, the two-hole lug to chassis ground) is always
required.
• Ensure the Kona Micro Outdoor Gateway Protective Earth Ground connection is properly
terminated prior to the connection of any other interface.
•
The Kona Micro Outdoor Gateway contains primary lightning surge suppression on the
Direct DC power port, the Copper Ethernet port, and the LoRa RF antenna port. The primary
lightning protectors have the ability to bridge the interface to chassis isolation boundary
during over-voltages. Ensure that the Protective Earth Ground connection is always in place.
•
Ensure that the Kona Micro Outdoor Gateway is secured to eliminate any physical hazard to
people or property. The Gateway must be securely mounted according to the mounting
instructions prior to any cable connection and operation.
•
The Kona Micro Outdoor Gateway does not contain a power disconnection device; a readily
accessible disconnection device must be incorporated external to the Kona Micro Outdoor
Gateway.
• The direct DC powered Kona Micro Outdoor Gateway shall be supplied through an input
overcurrent protection device rated not more than 10 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 Kona Micro Outdoor Gateway DC
supply.
