2 Installation
2.1 Safety Precautions
•
The Kona Macro Gateway must be installed in a restricted access location (such that touching
of the Gateway by non-service persons is not likely).
•
The Kona Macro Gateway may become hot to the touch during normal operation at elevated
ambient temperatures.
•
The Kona Macro 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 Macro 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 Macro Gateway Protective Earth Ground connection is properly terminated
prior to the connection of any other interface.
•
The Kona Macro 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 Macro 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 Macro Gateway does not contain a power disconnection device; a readily accessible
disconnection device must be incorporated external to the Kona Macro Gateway.
•
The direct DC powered Kona Macro 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 Macro Gateway DC supply.
•
For the direct DC power input, the DC positive pin must be at positive potential relative to
the DC negative pin. If the polarity is reversed, the unit will not sustain damage but will not
operate until the connection polarity is corrected.
