Maintenance - Kona Macro Gateway Installation

For Kona Macro Gateway

Written by Support

SAFETY NOTES

  • 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.

  • Although the Kona Macro Gateway can be powered through either the direct DC input or the power over Ethernet (PoE) input, simultaneous application of power to both inputs may result in unexpected operation and shall be avoided.

  • The Kona Macro Gateway power source must meet SELV requirements.

  • Always ensure the 3G/4G Modem SIM card access port is properly sealed after installing a SIM card.

Unpacking and Inspection Notes

The following should be considered during the unpacking of a new Kona Macro Gateway:

  1. Inspect the shipping carton and report any significant damage to TEKTELIC.

  2. Unpacking should be conducted in a clean and dry location when possible.

  3. Do not discard the shipping box or foam inserts as they will be required if a unit is returned for repair or re-configuration.

Required Equipment for Installation

The following tools are required to install the Kona Macro Gateway module:

  1. A 6 point metric socket set and torque wrench drive.

  2. Anti-oxidant compound (NO-OX-ID, Penetrox, Noalox, Ox-Gard or equivalent).

  3. A small wire brush.

  4. A clean cloth.

  5. Weatherproofing tape kit for the RF connector (Scotch Wireless Weatherproofing Kit, WK-101 recommended).

  6. Appropriately sized pipe clamps for pole mounting or appropriate screws or bolts (four sized M8) with any required anchors according to the wall construction for wall mounting.

Mount the Kona Gateway

Kona Macro Gateway is designed to be mounted to a vertical pole or wall using the supplied mounting bracket which attaches at the four screw locations on the back of the module (Picture 1).Ensure that the structure to which the Gateway is being mounted is secure and able to support a dead load of at least 136 kg (300 lbs). The areas illustrated below must be free of any obstructions to cable ingress.

Wall Mount

  1. Bolt the wall mounting bracket to the Gateway module using the supplied bolts and washers.

  2. Install 2 site supplied M8 bolts into the wall at 139.7 mm (5.5”) center spacing, leaving the bold heads protruding with a 2mm gap from the wall surface.

  3. Hang the Kona Macro Gateway with bracket from the two bolts by inserting the keyhole slots at the top of the bracket onto the 2 bolts and tightening the bolts.

  4. Insert and tighten two additional site supplied M8 bolts through the holes at the bottom of the bracket.

Pole Mount

  1. Bolt the wall mounting bracket to the Gateway module using the supplied bolts and washers.

  2. While temporarily supporting the Gateway with bracket, install the two site supplied pipe clamps, one through each of the upper and lower slotted clamp mounting points.

Install the Ground Cable

The Kona Macro Gateway is considered Permanently Connected Equipment and requires a permanently connected Protective Earth Ground (PEG) conductor. The Protective Earth Ground connection is made through a 1/4 x 0.75” on center double hole lug to the ground termination point illustrated in the attached picture. The recommended ground cable gauge is #10 AWG.

The Kona Macro Gateway grounding system shall follow local and national electrical codes. The Protective Earth Ground conductor terminated at the double hole lug point is mandatory and must be the first connection made to the Kona Macro Gateway during installation. Proper routing and termination of this cable is key to robust lightning withstand performance; in high susceptibility installations, every effort shall be made to minimize connection inductance and ground bed resistance.

The ground cable installation steps are as follows:

  1. Lightly abrade the surface of the casting ground area with a fine wire brush to remove the oxide layer.

  2. Use a clean cloth to remove any debris from this surface.

  3. Immediately coat the contact surface with a thin layer of anti-oxidant compound.

  4. Install the ground cable through its 2-hole lug onto the chassis ground point using the two supplied 1/4 - 20 x 1/2” bolts with flat and star lock washers, torqued to 10.4 Nm (92 in·lbs).

Install the RF Cable

The Kona Macro Gateway installation requires connection to a LoRa RF antenna. The RF cable attaches to the N-Type connector located on the bulkhead of the Gateway. Torque the connector to 1.7 to 2.3 Nm (15 to 20 in·lbs). The N-Type connector interface to a cable is not water proof and must be taped to be used outdoors. TEKTELIC recommends taping with Scotch Wireless Weatherproofing Kit, WK-101. Follow the taping procedures outlined by the supplier of this tape system.

The 3G/4G modem antenna is internal to the Kona Macro Gateway.

Install Copper Ethernet Cable

The Kona Macro Gateway Ethernet port may be used on a temporary basis for commissioning and maintenance or may be permanently connected for backhaul. When the port is not in use, the weatherproof protective cap must be installed. When the port is permanently connector for backhaul, the proper water-tight mating connector specified in Table 2 must be used.

The Ethernet cable must have minimum 24 AWG conductors and shall be rated for outdoor application according to local and national electrical codes.

Proposition 65 Statement: This product can expose you to chemicals including lead, beryllium & nickel, which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

Install a Micro SIM Card

To install a SIM card:

  1. Remove the SIM/USB cover. The SIM holder is above the USB port.

  2. Gently push the micro SIM card into the holder with the cut corner to the left and the SIM contacts facing towards the USB port as shown.

  3. Reattach the plastic cover and tighten to 10.5 lbf.in (12 kgf. cm).
